DOLMY repaired

Swiss made DOLMY Stopwatch has completed safe and successful so much!
It's far from ugly work but like professional one.
Because I have no experience on this kind of work, I wanted to send it to the professional person in Kanto area, he refused to do that if the movement is included being afraid of fracture in transits.
Such kind of accidental destruction might happen while transports especially on the precision devices, have I once on a German Synchro Comper mechanical shutter from Tokyo.
This is why I determined to do the work by myself without disassembling the chronometer.
I must appreciate from the bottom of mind  Mr. N**ai in Sagamihara city, but for his help to share me a precious parts, a shield glass for DOLMY, the work could not be accomplished at all.

Main wing construction

The main wing weak part is connection portion in Pegasus, according to my experience in the former model Pegasus ST, 100 flight invited some irreversible backlashes at the connection between aluminum pipe and holding holes because of the vibration of motor combustion including the stress while maneuvering, both phenomenon occurred, enlarging holes and thinness of Aluminum pipe.
The holding holes should be fitted tight with keeping some smoothness for insertion and disassembling, so to speak contradictory conditions must be satisfied.
I just imagined to apply Microflon, micro grain Fluororesin powder, in the wooden holes intending reduction of  sliding friction.
2 mm nutters would be invested in flying tail Horn portion to make them tightened firmly.
These kind of trifle attentiveness and ingenuity are indispensable for the better maneuver flight.
As Dr. Peter K. Thomas in UCLA said, "A trifle thing might be trifle, on the other hand, piled trifle things are not trifle but worthy enough!".

Escape habit

Swiss made stop watch DOLMY is on the way to be repaired in few days, because found I the replacement parts in Yahoo Auction while Net Surfing, Wind Shield Glass. The seller had huge amount of replacement parts and his advice to me was so warm and kind, also without any intention to earn more money as a merchant. Probably he must be an experienced craftsman with robust craftsmanship philosophy judging from his description of the items, also the prices he shows are not unreasonable rather than contributing in the field.
Some precious descriptions are scattered in his explanatory texts that cannot be written if he has not enough experiences and does not establish his precise technology and contributing phylosopy.

By the way, the Stopwatch is not mine but is committed to be repaired by the retired professor in the Agricultural division a few year ago.
From the beginning I thought it impossible to find out because of so specific and rare item, so it has been throwing away for long time before seeking the parts so consistently, but made a effort, did I a bit. Physical property innately I have, escaping habit might be a reason, I don't deny.
Consequently, I could come across with the seller in the Web Site the day before yesterday, as I have received an information to send me a precious part, it would arrive me at hand tomorrow. Probably, the professor must have forgotten the fact to have given me the item or he might regard me as an unreliable person?
I would like to be recognized by him the truth that there exist a strange person wearing persistent commitment in the world.
Any way I hope he would receive the repaired Stopwatch with surprise, pleasure and smile tomorrow, because he is the very person for not only me but for all his graduates of the University to be loved with the deepest admiration.

Confusion

TOYOTA Caldina AZT241W has covered 150,000 km and she makes me feel some problems in motor and trans axle mounting rubber insulators. Bounce shock stress is conveyed relatively directly. The advantage of this condition is surer steering feel because the heavy masses of the motor and the trans axle is connected directly on the nose portion. I can discern the noise of valve hitting movement while driving meaning the loose of the insulating effect.
The time is come to be replaced as the periodical replacement parts on the motor mounting insulators.
Then what will happen if the necessary maintenance is not performed?
Direct stimulation would be transferred onto the strut upper mount and rubber part would be torn off leading to the dangerous result.
Remember that all the wheels are replaced into new ones costing 100,000 yen the other day, huge expenses. I should use newly replaced tires more two years covering more 50,000 km to meet with the value for the expense.

On the other hand, my son is going to sell his VW Golf GTI model without any problem because he bought HONDA Step Wagon for his convenience to carry around his motor bicycle while long trips.
As an another choice for me, I might use Golf instead of Caldina as a matter of fact.
Now, I'm at a loss how to chose the way standing on the cross roads.

Pegasus Acro on the way

The fuselage and stabilizers, vertical and horizontal were completed for newly building YOSHIOKA Pegasus Acro.
As mentioned before, the designing of main wing is modified to be available for both original aileron style and Flying-Wing, the parts, 4 investing ultra thin radial ball bearing 15-21-4, #7602 and two pieces of 15-13-400 carbon tube.
Considerable expenses make me satisfied.
So, my idea for Flying-Wing in ordinary stunt model is going to be tried on Pegasus Acro. Mixing procedure on the transmitter might be complicated but interesting. The fixed horizontal stabilizer without elevator should be newly fabricated in addition.
I hope I'll enjoy several attempts on the newly constructed model airplane, because this is my own world not to be invaded.
The motor to be introduced would be OS 46 LA with YS fuel pressurized regulating system and the servos would be E-Max 9258 metal geared digital.

A new Idea!

Considering about Flying-Tail construction in Yoshioka Pegasus Acro led me an inspiration the trial on Flying-Main Wing. Recent carbon pipe central connective main wing construction might show me the possibility of FMW idea!
Looping and rolling are done only by the main wing instead of elevator and aileron, interesting! don't you think?
Also sophisticated Radio might it possible set up Flying-Wing program!
Eliminating moving part, ailerons on both side the main wing themselves move and change the angle of attack independently, the fixed horizontal stabilizer loses elevator leading to the elevator servo elimination.
As I'm keeping 50 years old trainer airplane Ikuta Flying Tiger low wing model but fuselage and stabilizers only, the main wing for this would be newly constructed inviting upper idea immediately, motor would be 32 or 25.
An abstract of designing is already rosen up in my mind, I will start immediately to draw the mechanical construction now.
If the result of this trial attempt were favorable, the idea would be introduced in F3A competition models in future.
I wanna see what'll happen ASAP!

Flying-Tail in Pegasus Acro

Yoshioka Pegasus Acro invites Flying-Tail design as it does, the supporting construction is very important, durability, accuracy and 3 dimensional backlashes.
Original designing is 8 mm dia. inner & outer sleeves Aluminum construction, it won't last 100 flight under 45 class grow motor vibration however some grease lubrication might be done well there, destructing energy caused by combustion phenomena should not be made little of even model small motor.
Because of the upper reason, I made up my mind to apply miniature ball bearing on the necessary portions.
Though I tried to follow the original design following instruction manual, only this complicated part was modified as my own. Weight increasing by the changing is very slight not to affect the original performance.
Stabilizers would be completed soon and a residual work is main wing construction, paying the best concentration not to distort at any rate.

Pegasus Acro started

I started to construct YOSHIOKA Pegasus Acro today, and initial step for fuselage is glued up. Wooden parts are well cut by means of LASER system.
Strength and redundancy system are well considered by the professional designer, many small parts are scattered everywhere intending weight reduction.
Very gentle handling is required by some experienced and trained pilot after completion, so this model airplane is not for a beginner but for adequately experienced one.
Pegasus Acro would makes a certain promotion to be controlled well as to participate in the future stunt contests. Very light and relatively large wing area design shows incredibly specific flight.
Because have I several suitable 40 class motors prepared for Pegasus ST model, I'm looking forward to try them on new model.
By the way, Pegasus ST was destroyed after 3 years using by my trifle mistake, vertical, low altitude and motor stop lacking fuel supply, I should not get riding well too much. Loosing power with low altitude leads to a critical crash, this is the same as an actual airplane.

Solex 34 PICT 3 main needle

I've realized that the main needle angular position on Solex 34 PICT 3 carburetor has some sharpened difficulty that has some relations with automatic choke control. As the 3ird party manufactured carb. used Bocar is mounted in my VW 1302 Super Beetle, a principle to adjust the original position 2 and a half turning back from the tightened angular position is not always meet with mine.
Probably, former user of this Bocar might have tighten too much in, so the needle valve hole must have been enlarged illegally.
Consequently, the angular position of main needle valve should be decided by my cut & try method repeatedly, very small and keen adjustment is required under this condition, not impossible but available. 470 degree turning back position of mixture control screw is my setting as a matter of fact.
Though the procedure for it relies on my sense and experience, mainly rely on exhaust smell, too much lean mixture produces excessive Hydro-Carbon and too rich Oxidized-Carbon instead.
Of course, spark firing timing and timing acceleration construction, both vacuum and centrifugal has much to do with the motor's combustion.
Because have I a struggled experience on Weber 40 DCOM side draft  twin carburetor as long as 10 years originally embedded in Peugeot Talbot 205 Rallye, the single carburetor adjustment is not so difficult task for me.
With mechanical Weber side draft twin carburetors, Regular Government Continuity Inspection had been passing instead of Private.
Experienced mechanic servicemen should know how difficult it had been on Earth?
I always say to myself and to my son, only experiences make a man.
Asking anything to others means being stolen precious and indispensable treasures by the others.

Precious rubber cup parts

Ordered brake rubber cup parts arrived from Tokyo for my VW Super Beetle 1302 costing 5,292 yen including Tax. Judging from ordinary common sense for these parts, ten times price, however they are unlikely as 45 years production air-cooled Beetle, how come?
I must inquire the rusting phenomena on the brake cylinder inside wall first, though I didn't neglect to change brake fluid every 3 years, occasionally, honing procedure must be done if the wall might have substantial oxidized deficiency.
Considering conscientiously, the cylinder inner surfaces should be processed by means of Chrome plating technology in to like a mirror, don't you think?
Because I touched everything, imagined I some fine omission work before I begin to change rubber cups into new ones.
In order to  prevent brake fluid leaking, I do insert a DIY 1 mm thickness round rubber pert between the rubber cup and the bottom of a sliding pusher part, counter-measuring 2-step stance.
Let's see what will happen, reporting later.

Used YS 60 FS

Arrived YS 60 FSH motor disappointed me a bit, that was made successfully bid in Yahoo Auction at 2,980 yen without competitors.
There exists no worn away evidence outside probably with very short period of time operation, but the ringed piston has apperent shinny spot at exhaust angular position also at opposite side meaning that the motor had been operated in very critical condition, too lean mixture loosing main needle valve setting. As a common sense, Ringed Piston has enough tolerance between the cylinder wall compared with ABC or AAC, in spite of the advantaged circumstance, the piston has shinny spots around the ring at higher position?
Probably, a former user must be failed in the initial break-in stage and a miserable YS 60 FS motor has been thrown away because of poor performance.
Crank shaft supporting main bearing has uneven ball wear not because of ordinary use but because of operating in the critical condition.
Now, I made up my mind to save this motor and to survive acquiring the original performance as designed by Mr. Yamada.
Removing concave surfaces on the piston wall caused by over-heating handling would be carefully reshaped avoiding unnecessary slipping resistor, piled carbon and sludge would be removed and the main bearing # 6903 would be replaced.
Following the Physical principle these kind of task is not always difficult.
Hoping this weeping and beaten-up motor would fly into the blue sky like a Phoenix in very near future.

OS 40 LA main port

Modification has accomplished on OS 40 LA forming the Schnierle main port successfully. The procedures were done on both cylinder sleeve wall and forming gas way inside the case. Keen concentration and special tools such as Carbide cutter were required to carry it out.
Because this modification is experienced on OS 25 LA motor last year, the task on 40 LA was not so difficult one but not so easy.
Later investigation about 40 LA models proved that the end stage production model has main Schnierle port, that has one piece rear cover plate with the needle valve body, not an independent metallic holding stay.
As I have formed the main port with oblique angled gas way to grow plug direction, manufacturer's design of it is horizontal parallel to the piston top surface.
I'm looking forward to compare my modification with originally 3 ported 40 LA model.

Troublesome wheel cylinder

Very slight stuck feeling just before stopping obliged me to investigate the reason, right rear wheel was the criminal. Though a rear wheel nut loosening procedure required some muscle work, I did it without hesitation.

Finding out some break fluid leak there at leading side sliding pusher portion, cleaning was done on the cylinder inner wall and pushing part on both sides. 

Any anxiety in break system spoils a fun to drive my VW Super Beetle, so the rubber repair kit was ordered to FLAT 4 VW shop in Tokyo before long. Ordered part might be expensive, small and tiny rounded rubber sealing and covering boots cost as much as 1,000 yen?

Anyway, fully overhauling including fluid replacement would be done while the holidays, the end of this year and a new year vocation.

Evasion is worse?

Is it worse to escape or to run away from something?
Is it better to fight or to confront to anything definitely?
Is there any fear to be isolated or to be a village odori?
An inquiry by some 13 years old girl, " Why is it wrong to escape, any beasts go away from things unpleasant or dangerous?" moved me so much.
The cultural society has a tendency not to recommend evasion, for example, a soldier who escaped from strategy front is easily killed by rife shooting done not by the enemy but by friendly force.
Are we obliged to obey blindly the unexplainable manners and customs in peaceful days here now?
Of course I know that, in order to keep some group in peaceful condition, there must be any decisions to be followed, person who cannot accept the Law would be isolated or be bounced off.
We often stand on the point to choose, stay or escape.
A safest way of living in a group is obeying and following the Law, thinking, saying and behaving the same as others.
A person who do not accept decided manners and customs should leave the group.
Incidents and conflicts happen in a Family Society in the World.
Probably, he or she would see another comfortable world outside after that.
So, we don't have any reason to deny to run away, to leave or to escape however difficult to do that in a settlement society.

Oil deterioration at low temp.

Now we got into winter season in Japan and the temperature outside became lower than zero centigrade.
Following the circumstantial change, the physical property of materials changes also especially the viscosity of oils in a car.  As the brake fluid is not made from mineral one but from vegetable one, deterioration and degeneration of liquid material sometime causes clogging in a mechanical constructions, among them operative brake cylinder inside is not be ignored at all.
My VW Super Beetle has drum designed brake systems on 4 wheels, 5 years interval  from the latest maintenance needs periodical checking if the systems keep working, a possibility of one hand operation would be doubted, leading side or trailing side.
I'm going to proceed to a muscle working on the break system maintenance today, but it's relatively convenient for me to do that because the temperature is low and I need some athletic training these days.

Wondering in the Web site this morning, I happened to come across an interesting lecture about Emotional Condition, the comparison between the ancient nomad people lasted for 10,000,000 years till the agricultural race appeared and the settlement ethnicity, lasting for 10,000 years. The influence in people's mind caused by the Settlement Restraint is very impressive and moved me so much and I would like to dig this title a bit more.

Detuned OS 40 LA

I have realized the truth that OS 40 LA motor lacks a Schnierle main port but only side ports aside, how come! ? Instead of 46 LA motor's 3 Schnierle ports?
I understand that the lower graded motor should not have some similar performance and potential with that of higher graded ones from the manufacture's standing poiint of view.
According to the manufacturer's strategy, important and indispensable machining prosess must have been eliminated intentionally.
But, I hear a deep shout by 40 LA motor, " I have much more potential if I'm machined the same as elder brother motors, probably you can do that!?".
So, I determined to do that, with contrary to the maker's speculation, the same procedure had been done on OS 25 LA motor previously and it's performance came to the same revel or more as OS 25 top models.
The original case designing has convex shape for Schnierle main port and the thickness for a main port is enough to be engraved inside.
In order to establish the port on a cylinder wall and engraving gas way inside of the case, keen and fine technologh might be required if it might be done by an outsider manually.
Breakthrough chilidish strategy is one of my exciting pleasure!
The result would be prooved in some model airplane competition scenry.
Reporting about this interesting affair later.

Detonizzato OS 40 LA

Ho realizzato la verità che il motore OS 40 LA manca di una porta principale Schnierle ma solo le porte laterali a parte, come mai! ? Invece di 46 porte Schnierle del motore LA?
Capisco che il motore con un grado più basso non dovrebbe avere prestazioni e potenzialità simili a quelle di quelle di livello più elevato dal punto di vista del produttore.
Secondo la strategia del produttore, un processo di lavorazione importante e indispensabile deve essere stato eliminato intenzionalmente.
Ma, sento un forte urlo da parte di 40 LA motor, "Ho molto più potenziale se sono lavorato allo stesso modo dei motori fratello maggiore, probabilmente puoi farlo !?".
Quindi, ho deciso di farlo, contrariamente alle speculazioni del produttore, la stessa procedura era stata già eseguita sul motore di OS 25 LA e le sue prestazioni sono arrivate allo stesso entusiasmo o più dei top model di OS 25.
Il design del case originale ha una forma convessa per la porta principale di Schnierle e lo spessore per una porta principale è sufficiente per essere inciso all'interno.
Al fine di stabilire la porta su una parete del cilindro e l'incisione del gas all'interno del case, potrebbe essere necessaria una tecnologia appassionata e raffinata, se potrebbe essere eseguita manualmente da un estraneo.
L'incredibile strategia infantile è uno dei miei eccitanti piaceri!
Il risultato verrebbe dimostrato in alcuni scenari di concorrenza di aeroplani modello.
Riportando su questo affare interessante più tardi.

OS 40 LA & 46 LA con sistema YS

Sono stato sorpreso di aver smontato OS 40 LA e 46 LA, precisamente la tecnologia di precisione, inclusa la precisione e la finitura del getto di metallo, le boccole di bronzo sono state inserite mediante il metodo di fusione simultanea nelle parti necessarie nel caso, supportando l'albero motore. La bussola del cilindro è più sottile al massimo con il metodo di taglio, ma in seguito viene sostituita con il metodo Flange Flange.
Sebbene non abbiano i cuscinetti di supporto dell'albero motore, secondo la mia percezione, non sono sempre necessari per l'uso normale se il motore viene utilizzato 12.000 giri al minuto, piuttosto che essere rilasciato da alcune fastidiose cure di manutenzione dei cuscinetti, progettazione dei motori più leggera e sottile è preferibile se gli spostamenti sono uguali.
100 gr di peso sulla parte del naso fusoliera influenzano una progettazione di aeroplano fondamentale che si riferisce al rapporto momento naso e coda, posizione CG.
L'impostazione di un raccordo di pressione sui carter del motore è uguale a quella menzionata prima della scanalatura della larghezza dell'impulso dell'albero a gomito e della modifica del tamburo del carburatore. I carburatori sono sostituiti da quelli originali a OS 2C per le corse automobilistiche con diametro della gola di 7,0 mm, non solo per la massima potenza, ma hanno il meccanismo di spremitura del carburante all'operazione più bassa.

OS 40 LA & 46 LA with YS system

I was surprised to have disassembled OS 40 LA and 46 LA, precisely fine machined technology including metal casting accuracy & finish, bronze bushes were inserted by means of simultaneous casting method at necessary portions in the case, supporting crank shaft. Cylinder sleeve is thinner utmost by cutting method but later changed into Flange rolling method.
Although they do not have crank shaft supporting bearings, according to my perception, they are not always necessary for ordinary use if the motor is used under 12,000 rpm, rather than I would be released from some troublesome bearing maintenance cares, lighter and thinner motor design is preferable if the displacements are the same.
100 gr weight on the fuselage nose portion influences a fundamental airplane designing relating on the nose & tail moment ratio, CG position.
Setting a pressure fitting on the motor cases are the same as the manner mentioned before including crank shaft pulse width grooving and carburetor throat drum modification. The carburetors are replaced from original ones to OS 2C for car racing with 7,0 mm throat diameter, not only for ultimate power but they have fuel squeezing mechanism at the lowest operation.

ENYA 45 CXL modification

A pressure nipple was set on ENYA 45 CXL with the same manner as ENYA SS 35. Fully disassembled as usual and the crank shaft on intake port was engraved to establish adequate pressure timing for 105 to 160 ATDC pulse width precisely.
Without this modification for YS fuel pressurized regulating system, this motor would lose the opportunity to be used for F3A P19 maneuver pattern purpose.
The mechanism in ENYA G type carburetor with fuel squeezing makes it possible to invite YS system.
Special designing, Aluminum-Chrome plated cylinder and Aluminum piston would  make a good performance and it's longer life.
So, any ordinary motor with fuel squeezing construction carburetor could be possible to operate under fuel pressurized condition.
The throttle barrel throat lower hole was enlarged to prevent orifice effect, this is an indispensable modification for motor stable operation at the lowest speed.
Any main needle valve setting with deception under natural aspiration is not required, because pressurized fuel supply amount would be kept so stable in any attitude of airplane, rising up or coming down, from the beginning to the end of the maneuver. Also, any fuel tank burdening position in the fuselage is acceptable even at tail end, most of the time very near CG position.
It is not notified the true potential and capability of the motor until it is actually used under fuel pressurized condition, once the fuel mixture is decided, the supplying fuel condition does not changed, no matter how rising up or downing phase or the beginning of the maneuver pattern or the last stage.

TETRA Rookie 20 Refreshment

Refreshment of TETRA Rookie 20 is completed, motor replacement from OS 32 F to ENYA SS 35 and fixed nose gear to steerable one. No movement of CG occurred as a matter of fact. Though, 35 motor might be recommended that too much for the 20 class trainer, just overpowered leading to an unable woman, F3A pattern maneuver on windy condition requires unbalanced motor power.
Probably, precise motor controlling technique might be obliged to keep stable flight.

I wanna ask to myself that do I do my works more conveniently, more quickly!
Do I make myself in a comfortably warm spring bathing?
A trifle person like me has a tendency to lead a life with eating full, oversleeping and  wasting time, especially a dragonfly living in a Paradise, in Japan country with no aggressive fighting, no starving, no dangerous circumstances even in the middle of the night.
Situated in Far West US Strategy Front as Japan country is, we are keeping a peaceful daily lives here, is this phenomena brought just because of Japanese Peace Constitution? Or, because of US military air bases scattered all over Japanese land, 84 in number?
Should we Japanese nation recognize the fact and truth that the occupation by US has been long lasting since the end of WW2?
Remember that a cleared up blue sky also exists in a biggest Typhoon Core Center!

Throttle modification for YS system

The most important requirement is often lost to modify ordinary motor to YS fuel pressurized regulating system. Orifice effect in the throat while low speed operation should be removed to obtain stable rotation.
In order to do that, lower part of throttle valve must be opened freely when drum type throttle construction is invited, otherwise YS system would not demonstrate it's performance enough. So, the throttle valve must accept some irreversible modification, no return to natural aspiration.

Replacement parts

ENYA SS 35 was disassembled only on the front housing portion for the purpose of setting up pressure nipple, in combination with YS fuel pressure regulating system.
The bearings for main crank shaft supporting is #6901 and for front is R4A inch size promptly. The capacity of their road is adequate design for this 35 motor.
Careful scaling was performed to establish the most suitable pressure withdrawing timing, nipple position and crank shaft engraving point both are very important requirement for proper performance of the regulator, between 105 and 160 degree value ATDC is the key to success.
As for an original carburetor, 6,5 mm throat diameter is designed for the use under natural aspiration condition, but judging from an actual scaling the port gas way in the crank shaft, 7,5 mm diameter, more 1 mm wider throat wold be effective for the ultimate performance if operated under fuel pressurized condition.
Consequently, ENYA GM type carburetor with 7 mm diameter throat is invited for the upper purpose. The mechanical construction of GM carburetor makes it possible to adjust mixture as to attain the best low rotational condition not only natural aspiration but fuel pressurized conditions.
The reputation of SS 35 among the modelers is not so favorable because of narrower in take gas way in the crank shaft, but my modification would thoroughly wipe out such kind of rumor, YS fuel pressurized regulating system is the only way to do that.

Rookie 20 maintenance

Long awaited modification is not on the way on TETRA Lookie 20 trainer airplane.
Because the surface condition of flying place is flat well, fully plated with dubber mat, too much distance the airplane goes without stopping.
So, steering function on the nose gear is indispensable at all. This is why I made up my mind to apply TETRA Nose Gear S type on Lookie 20 in stead of fixed one.
The performance of OS 32 F could be understood enough in combination with YS pressurized fuel regulating system, so the motor would be exchanged into ENYA SS 35 that is light enough to meet with OS 32 F. A pressure nipple to withdraw pressures for pressure signal activating the regulator in adequate timing.
Indirect mounting mechanism should be fabricated again utilizing L shape cross section Aluminum Alloy material by myself.
These modifications are very simple as described, but they are relatively complicated and time consuming task.
It became cold outside, so now is the time to be spent for working table tasks rather than going out for flight.

ASO 88th Regular Concert in Fukushima OSAKA

We enjoyed utmost Classic Concert this evening, Ashiya Symphony Orchestra 88th Regular Concert, also ASO 50th anniversary special Concert was held at Fukushima The Symphony Hall OSAKA. And it was successfully performed as usual under the conductor Mr. Kazusi Yamashita. Additionally, beautiful vocal encore was done for the sake of the spirit of disaster in Tohoku area a few years ago, actually the made a concert tour at Ishinomaki on 3ird in November, at Sennan Art and Culture Center on 4th November, and today.

We are longing for the next ASO Concert next Spring.

Accidental affair

I was disappointed to know that OS does not supply the part of 7DV carburetor spray bar any longer because of old model. As I have been suffering from stuck feeling at the fuel squeezing construction from new condition. This strange phenomena should be caused by some low manufacturing(poor quality control) by the manufacturer. So, I tried to establish the centrality of spray bar inclination by inserting metal rod inside, applied stress damaged splay bar slit portion by chance and incredible breakage happened along through the slit miserably as a matter of fact, Oh my God!  Fuel squeezing mechanism in 7DV carburetor has lost completely, how come?
The carburetor should be brought to OS service front asking any countermeasure before I did poor action on it, then they must have done well with it as usual.
This destroyed part had been thrown away for long time because of the reason.
Just I imagined the way to rescue this lonely one by myself imitating the fuel passing ways in YS 60 FR motor, yes, engrave the sharp triangle passing way on the throttle valve and carburetor body inside.
Deeper consideration should lead me to do that because have I a good control in front of me.
Several precise modifications must be required on the way of machining procedure, but I'll do that once the idea comes in to my mind.
Wanna I fulfill my ambition, it is interesting, don't you think?
Of course OS 61 RF rear exhaust port type motor would be operated in combination with YS fuel pressurizing regulator system.
Reporting on this interesting trial attempt would be done later.

Super Beetle brake maintenance

As I felt some strange feel at the state just before stop, inspected I front wheels of
 Super Beetle by lifting up, then unacceptable rotational resistance was observed in right side wheel, so to speak stuck feeling.
Following the natural countermeasure for this inconvenience, the brake drum was removed, no problem was found out in wheel bearings, inner and outer.
Careful checking on the operative cylinder, the sliding pusher for the trailing side was cohesively stuck. This kind of banish like material might have come from gradual leak of brake fluid or denaturing of silicon grease applied at assembling stage.
Removing all the banish there and reassembling the construction re-obtained the natural function again.
Whenever we start the brake maintenance work, some dust sheet under the wheel must be prepared, otherwise, the pit floor would be spoiled as shown in the picture.
I felt the necessity to check brake construction periodically, the maintenance sheet by the constructors is not prepared unreasonably.

YS pressurized fuel regulating system

Though the performance and stability in actual use is already proved by the manufacturer, their regulator system is available or not on another motors by different constructors except Yamada under the natural aspirating carburetor fuel pressurized condition. According to the opinion(probably scientifically proved by actual measurement by the company) The pressure value of the first stage compression in 2 cycle motor crank case is the same no matter how the displacement value might be different, meaning that the first stage pressure value is the same in the smaller motor as 10 cc motor. We might regard it smaller in a smaller motor, but they are the same value, even in L.M. Cox 010 cu inch motor. So, my curiosity to prove the fact if it is possible or not, to apply the system on another motors, it is a simple but long lasting reason why I have been advocating on this point.

The way of experiment
The pressure nipple was set on the front part of crank case for the purpose to pull out the first stage presser that compress the fuel tank to supply pressurized fuel to the carburetor and controlling the fuel amount adequately and supply stable amount according to the motor speed under some changeable burdening condition in the maneuver scenarios. YS regulator is mounted on somewhere nearby the motor independently.

The requirement for operating YS regulator system in steady state
No pressure leak in fuel line and pressure line including one way valve and fuel strainer and regulator such as small grain dust or fiber material from the textile.
Pressure nipple(pressure extracting point and duration) should be properly between 105 degree and 160 degree ATDC. The pressure extraction angle value is very important to obtain the most effective controlling avoiding pressure fluctuation caused by fundamental 2 cycle piston valve construction. The stable pressure supply contributes not only to the tank burdening position, most of the case it is near CG point but also to the linear carburetor action in combination with the diaphragm regulator system. Requirement of the carburetor YS fuel pressure regulator does not have the capability to control the fuel amount at the lowest throttle position. The diaphragm control is not so linearly at the throttle closest position.
Consequently, it should be controlled by carburetor construction by means of fuel squeezing mechanism such as an additional opposing needle or slit closing spray bar designing. Air through controlling screw is not always necessary here. ENYA G-type carburetor is available if the fuel way should be closed utmost following the groove engraved on the throttle valve drum surface.

Gnathologisches Instrument
Gnathologisches Instrument Bedauerlicherweise geschah eine elende Angelegenheit.
Ein kostbares und teures articulater, Charles E. Stuart entworfenes völlig justierbares Gnathologic-Gerät im zahnmedizinischen Feld verschwand im Museum, das Fall zeigt.
Ich fand es zufällig in der Lagerstätte im Zustand des Verlustes der Schneidezahnführung und des abgetrennten oberen Gipsverbandes.
Als ich fragte, wo es sich um den Chef des Zeuges handelt, antwortete er, dass es irgendwo ist und er es später suchen würde, wie lange ich auch den ganzen Tag warten könnte, die Zeit, den Ort zu schließen, er bereitete sich darauf vor, nach Hause zu kommen. zu ihm, dann bring es mir morgen.
Wahrscheinlich dachte er widerstrebend, er bediente die gebogene und verzerrte Führungsnadel mit der Entschuldigung für den Fehler, der von einem der Dinge verursacht worden war. Aber er hat nie erklärt, wer es mit Namen getan hat.
Fallunfall war der Grund, den Artikulator zu verbergen!
Laien oder Laien verursachen manchmal solche Fehler, weil die oberen und unteren Bögen in Arcon-articulater getrennt sind, nicht im Scharnierbereich.
Er hat sich entschlossen, die Strafe durch eine gemeinsame und multiple Verantwortung zu bedecken, es ist nichts anderes als eine japanische Denkweise, als ob er eine Person mit warmem und sanftem Geist wäre.
Er versteckt die Beweise für immer oder bis es offensichtlich wird?
Auf der anderen Seite habe ich eine andere Art zu betrachten, dass ich und betone den Punkt, die Bedeutung ist, wie wir den Unfall entgegenwirken können, reparieren oder ein neues Teil an den Hersteller bestellen.
Sich zu verstecken oder sich anzuziehen, als wäre nichts geschehen, ist nicht der richtige und faire Weg. Sorgen in seinem Kopf ließen ihn das tun?
Ich missachte oder bestrafe niemals irgendeinen Fehler, wenn es nicht absichtlich geschehen wäre.
Die Wichtigkeit ist die Gegenmaßnahme unmittelbar nach dem Unfall!
Wir sollten gemeinsam über das Problem nachdenken, wie das geht, es hat nichts mit der Bestrafung einer bestimmten Person zu tun.
Ich muss das mit einer sanften Ablenkung, etwas schwierig, einer anderen Generation von Jungen und Mädchen beibringen.
Erinnert an meine Vergangenheit, bestrafte mich mein Chef im Institut der Graduierten-Universität am meisten, wenn ich nicht allein, sondern allein getan worden wäre, ich habe die schlimmen Umstände ertragen, weil diese Art von Entbehrungen Energie und Kraft sein würde, um mich selbst zu leben. diese Zeit. Und ich stellte fest, dass ich niemals die Person wie er sein würde.

Gnathological instrument

As a matter for regret, a miserable affair happened.
A precious and expensive articulater, Charles E. Stuart designed fully adjustable Gnathologic device in Dental field disappeared in the museum showing case.
I happened to find out it in the storage place in the condition of being lost of  incisal guide pin and separated upper plaster cast.
When I asked where it is to the chief of the stuff, he replied it's somewhere and  he would seek it later, however longer I might wait it all day long, the time to close the place, he prepared to come home, and I said to him, then bring it to me tomorrow.
Probably he reluctantly thought, he served the bent and distorted guide pin with apologizing the fault caused by one of the stuff. But, he never declared who did it by name.
Falling down accident was the reason to hide the articulater!
Layman or laywoman cause such kind of mistake sometimes, because the bows upper and lower are separated in Arcon type articulater, not jointed in the hinge portion.
He made up his mind to cover the punishment by a joint and multiple responsibility , it's nothing but a Japanese way of thinking as if he looks a person with warm and gentle mind.
He keep concealing the evidence forever or until it becomes obvious?
On the other hand, I have different way of regarding that I put and emphasis on the point, the importance is how we can countermeasure the accident, repair it or order a new part to the manufacturer.
Hiding or dressing up as if nothing happened are not the correct and fair way to go. Sorrowfulness in his mind let him do so?
I never scowl or punish on any mistake if it had not been done intentionally.
The importance is the countermeasure immediately after the accident!
We should think over about the problem all together, how to do that, it has nothing to do with the punishment applied on a specific person.
I must teach about that with some gentle distraction, a bit difficult, to a different generation boys and girls.
Remembering my past, my Boss in the institute of the Graduated University punished me utmost if it had not been done by myself but by himself, I endured on the sever circumstance, because this kind of hardships would be some energy and power to live myself at that time. And I determined that I would never be the person like him.

40 years old ENYA 60 X

A radial mount for ENYA 60 X was fabricated with wooden plate to be burdened on a flying motor testing airplane, Sukhoi 31.

Though the radial mount  is set on the bulkhead by way of 4 points rubber insulator, I designed to support with rubber plates in addition for the purpose of avoiding combustion knocking vibration. This kind of mounting method might spoil the true maximum and ultimate performance of the motor, but the effect of prolonging the lives of potentiometers in the servo's construction as well as of all the moving parts in the airplane. 

Rubber insulators for the motor mounting take effect for silent flight, vibration and combustion noise including that is produced by propeller's cavitation in the sky and that is similar with combustion noise. Most of the noisy air plane amplify both noises on main wing and fuselage surfaces, in short, they play a part of noise amplifier in the sky. This is why the method to separate the noise causing origin with airplane body at the point of the first bulkhead by means of setting any insulation materials, rubber.

But, remember here, a slight fluctuation on the motor thrust line affects on the flight, most of the pilot might feel some funny reactions to every direction.

Considering the physical property of the viscoelasticity in rubber material, below JIS #70 coefficient is not  recommended for the purpose here. 

This motor had not been operated as long as 40 years just after once testing operation with Tuned pipe on Curare 60.

As a secret information, the main crank shaft supporting bearing is a very seldom one, the outer lace diameter is 2 mm wider than ordinary #6903, so the engraving on the front case for supporting bearing does not accept #6903 so far as the space here should be fulfilled, a ling spacer must be required if popular one is desired.

This is why ENYA 60 X has not been used as my first line fighter's motor, however deeper I might love the specific character of ENYA 60 X, good performance producing stout construction and Aluminum alloy-Chrome plated cylinder design.

שריר עבודה על VW חיפושית סופר

בעיה קריטית קרה במחשב הראשי שלי הבוקר, איך זה קרה? זה לא מתחיל בכלל, AD-Aware ותוכניות Spybot SD רץ אמש, כי היו הסיבה לתקלה? עכשיו אני יודע כמה אני מסתמך על מערכת אינטר נטו לחיי היומיום שלי. אני לגמרי מחזיק מעמד המצב!
התקנה מחדש של מערכת ההפעלה ב HD החדש פתר את הבעיה הפעם, אשכול התנגשות עשויה להיות הסיבה.

רדיו אתלטי אימון הבוקר נזכרתי על העבודה שריר על שלי VW סופר חיפושית אתמול.
אם לשפוט על פי שיטה ראו דרך על גלגל קדמי חזית במצב ine, ערך רב מדי נצפתה, ההיסטוריה הבלתי נשכחת בעבר נקרא שוב, הרס מוחלט של השיחים התחתונה זרוע התחתונה, הייתי חייב לעבוד שרירים הגדול ביותר!
תגובת ההיגוי מוזר תוך כדי הסתובבות, התנגדות מכנית קלה מאוד רק כאשר היא מפסיקה בלי בלימה המבצע, הרגשה נהיגה לא מוסברת רע, יציב היגוי עמדה מרכזית, כמה אי הנוחות שנצפו.
למעשה, אתמול נאבקתי, למעשה, החלטתי לפרק את בניית הצירים הקדמיים כדי לבדוק את מצבם של שיני הצירים, שברי הגומי בהם.
לא היתה בעיה מוזרה נמצא שם אחרי הכל, אז מה גרם אי התאמה על ערך נגרר, 11 דקות ערך זווית?
כנראה לדמיין אותי כי הלחץ המתמשך מכיוון מסוים עלול לגרום ללחץ אלסטי קבוע של התכווצות חומר גומי בין השיחים, זה סוג של תופעות כמה פעמים קורה.
זכור כי משקל הנהג על המושב לא צריך להישכח בעת מדידה והתאמת על יישור ההגה ואת בניית סרן, שהוצג לעיל, 3 מקרים פולי מלא מים 18L נקבעו במצב.
בכל מקרה, הנוהל של dis- הרכבת ועקב מחדש הרכבה של בניית סרן הרכב גורם לי להרגיש עייף כל כך, זה נגרם על ידי הזדקנות?

Muskelarbeit am VW Super Beetle

Kritisches Problem ist heute Morgen auf meinem Hauptcomputer passiert, wie kommt das? Es startet überhaupt nicht, AD-Aware und Spybot SD-Programme liefen letzte Nacht, das war der Grund für die Fehlfunktion? Jetzt weiß ich, wie sehr ich mich für mein tägliches Leben auf das Inter-Net-System verlassen habe. Ich bin völlig in Aufrechterhaltung!
Die Neuinstallation des Betriebssystems in neuem HD löste das Problem dieses Mal, Cluster-Clash könnte der Grund sein.

Radio Athletic Training heute Morgen erinnerte mich an die Muskelarbeit an meinem VW Super Beetle gestern.
Nach einer durchsichtigen Methode an den Vorderrädern war zu viel Wert zu beobachten, eine unvergessliche Vergangenheit wurde wieder aufgerollt, die komplette Zerstörung der vorderen Unterarm-Gelenkbuchsen, ich war zu einer größten Muskelarbeit verpflichtet!
Seltsame Lenkreaktion beim Wenden, sehr geringer mechanischer Widerstand gerade wenn sie ohne Bremsvorgang stoppt, unerklärliches schlechtes Fahrgefühl, instabile Lenkzentrierung, einige Unannehmlichkeiten wurden beobachtet.
Ich wurde gestern tatsächlich gerungen, ich entschloss mich, die Vorderachsenkonstruktion zu demontieren, um den Zustand der Scharnierbuchsen und den Bruch von Gummi in ihnen zu untersuchen.
Es wurde schließlich kein merkwürdiges Problem herausgefunden, was machte dann eine Diskrepanz beim Tow-In-Wert, 11 Minuten Winkelwert?
Stellen Sie sich wahrscheinlich vor, dass die andauernde Belastung aus einer bestimmten Richtung die dauerhafte elastische Spannung in der Gummimaterialkontraktion in den Büschen verursacht haben könnte, diese Art von Phänomenen passiert manchmal.
Denken Sie daran, dass das Gewicht des Fahrers auf dem Sitz nicht vergessen werden sollte, während Sie die Radausrichtung und Achsenkonstruktion messen und einstellen (siehe oben). 3 mit 18L Wasser gefüllte Polykoffer wurden in Position gebracht.
Wie auch immer, die Prozedur der Demontage und des Wiederzusammenbaus der Achskonstruktion des Fahrzeugs macht mich so müde, dass sie durch Alterung verursacht wird.

Muscle work on VW Super Beetle

Critical problem happened on my main computer this morning, how come? It does not start at all, AD-Aware and Spybot SD programs ran last night, that were the reason for the malfunction? Now I know how much did I rely upon Inter net system for my own daily life. I'm completely in holding up condition!
Re-installing operation system in new HD solved the problem this time, cluster clash might be the reason.

Radio Athletic Training this morning remembered me of the muscle work on my VW Super Beetle yesterday.
Judging from a see-through method on frontal wheels toe-in condition, too much value was observed, unforgettable past history was called up again, complete destruction of front lower arm hinge bushes, I had been obliged a greatest muscle work!
Strange steering reaction while turning, very slight mechanical resistance just when she stops without braking operation, unexplainable bad driving feeling, unstable steering centric position, some inconveniences were observed.
I was wrestled at all as a matter of fact yesterday, I made up my mind to disassemble the front axle construction to inspect the condition of hinge bushes, rubber fracture in them.
No strange problem was found out there after all, then what made discrepancy on tow-in value, 11 minutes angle value?
Probably imagine I that the continues stress from a specific direction might have caused the permanent elastic strain in rubber material contraction in the bushes, that kind of phenomena some times happens.
Remember that the driver's weight on the seat should not be forgotten while measuring and adjusting on wheel alignment and axle construction, shown above, 3 poly cases filled with 18L water were set in position.
Anyway, the procedure of dis-assembling and following re-assembling the vehicle's axle construction makes me feel tired so much, it is caused by aging?

OS 40 FSR

OS 40 FSR schnuerle motor is one of the most popular over 35 years ago. Schnuerle scavenging combustion system, good case designing and precise finishing made it's reputation unmovable, also it's carburetor had fuel squeezing mechanism and it was operated so stable and so smooth well not only on ordinary flying models but also on stunt maneuver contest scenery. 
In spite of the holding of crank shaft main bearing is not fully covered, the thickness of front case mainly supporting crank shaft is stout with no vulnerability leading to some certain operation.
Crank shaft bearings F/R are R6Z and #6902 proving enough gas port area grooved in the shaft and sophisticated designing carried out to establish a perception as the first class operating product.
So, ultimate performance could be obtained not only by an experienced flyer but also by a layman pilot so far as the rust is avoided unexpected appears in the bearings, piston ring.
ABN P/C model could be chosen in later model, the difference between a ring piston one is not be distinguished, on the other hand operation noise of  ABN model is higher than the former model.
The technology for producing this kind of Schnuerle motor must have established at that period, though one piece case technology and machinery precision have remarkably advanced these days.
Noisy performance operation is not accepted by ordinary inhabitant these days because of Noise Pollution, the quiet and calm operation is desired except some specific field such as Pylon Race and Rat Race. Probably, this is why 4 cycle motor or Brushless motor source are accepted including breaking effect while downing phase.
