Dealing estate in vain

The dealing estate for my son's new house has broken off the other day. The price we presented was exactly the same as that of the recommendation price by the seller's real estate agent! But, the seller insisted 2,000,000 yen higher one, so the result was that. The agent has enough information about current market price and they served the price to the seller, of course that is nothing but the higher price seller concessions advantage, and the dealing should go well with buying and selling established, our price is more reasonable than ordinary dealing without any price cut negotiations. The seller suspected the secret agreement between the agent and us, because the prices were the same from a common-sense standing point of view. Any way, all the the efforts exerted this time were in vain. Becoming emotional is worse for a big dealing, not for us but the seller. 

Criminal found

Removing the rain guard boots, I found out the criminal to have caused dysfunction on the rear door locking mechanism in B-Vectra just now. Killing the function of the outer handle there was considered in the beginning, repairing this circuitry would recover the original function.

Broke

The door lock system of right rear door became out of order, it closes but without locking. This kind of inconvenience must be brought by any disconnection of wiring on the moving portion in show with arrow. Removing inner door cover and reconnection procedure would be required. This work has risen up as a complicated one, it would be done soon otherwise B-Vectra cannot be used if left unlocked outside.

NHK TV program early this morning showed how to think about historic cultural heritage, it is regarded as the way to connect the ancient persons with us living now. The connective bridge between old time and sensitivity are the indispensable property of heritage.  I have learned about this fact from a great leader, Professor Kiyomi Sakaguchi.

Low Life VW Meeting

Today participated I in a event held at Yamazoe village in Nara Prefecture, Low Life VW Meeting. All of the car gathered together have been modified devising deeply, though the way of thinking is different from me at all.

Maintenances

AC power controller was fabricated by myself with making use of Wonder Kit PC-16A printed circuit plate. This kind of semiconductor circuitry is indispensable for precise rotation control of a grinder and sharpener devices.

The air duct fixation was performed in VW 1302 Super Beetle engine room that was necessary but left undone for long time, because it fell down so often after a long driving. As the duct was set in different way from the original design because of a cooler cooler compressor equipment retrofit, that caused some tendency to fall down, remembering the past, the duct was not found from the beginning. Heat and vibration must have brought this inconvenience. Now, such kind of anxiety would be eliminated thoroughly, butyl rubber self fusing tape applied the portion and Ju-Billie band would make the fixation surer from now. Hitting and slipping noise discerned from outside that caused by fallen duct and crank polley resembles that caused by lack of lubrication grease in the generator main shaft supporting bearings.

Steering gear box backlash

Elimination of backlash on worm gear steering gear box in air-cooled VW1302 Super Beetle has far progressed it's behavior, urging me of re-consideration on the rear axle compliance mainly on the trailing arm rubber bush hardness. Special lubricant was applied inside in addition, well kneaded Microflon powder was added at the same time preventing gear wear. Though I thought that some unstable steering reaction must have been brought by the lack of lateral stiffness of the arms, I realized that the backlash in steering linkage also has much to do with this kind of inconvenience. I am going to try deeper on this point with more experiments.

Winter season soon

Typhoons are coming across to Japan main land one after another these days, #27 and #28 are about to be near to us. The weather condition this week end would not be favorable for any Autumn outdoor affairs and this winter must be cold for those with no warm memories. Canyon Kurobe was now in the moment just before winter season, Autumn Leaves were not yet there last week when I visited.

Street view camera?

I came across with a specially modified SUBARU Impreza in Southern Eastern part of Kyoto the other day. Thanks to the desperate and continuous efforts by the company, we can easily recognize Google Map Street View any time we want. A few cameras are set on the ceiling of the car and the shots would be obtained in different shooting directive angles from the same point.

Also MD100-200 on EOS

Riding on the momentum of Minolta lenses modification, did I the same also on MD Zoom 100-200 without getting tired yesterday evening. No anxiety on innate 0,50mm shorter flange back discrepancy was not to the point in actual adaptation work as the same reason with MD 75-200. This lens had been produced for a long time from initial announcement with just changing the outer shape of barrel designs, so MD and MC 100-200 have exactly the same optical design for long period of time, in another words, Minolta had not been obliged to change it because it has good enough physical performance to go well further more without any dissatisfaction in actual specifications. It looks longer than the later model, MD75-200 but with less weight. This old designed but with good performance lens would be one of my enjoyable one from now.

MD 75-200 on EOS

0,30mm step on the outer circle of the flange surface and removing the lens-back adjusting sim 0,2mm could have eliminated the discrepancy of flange back difference between Minolta, 43,5mm and Canon EOS 44,0mm. So, no complicated lens element or lens mount case length adjusting were not required on New MD Zoom 75-200. Following my selfish and fixed perception on the magnification of focal length, the less magnifying F/L, the more physical property and performance of zoom lens would attain, this 3 times variable F/L MD 75-200 might have superb performance on earth. I'm looking forward to try this tomorrow.
As shown in the upper descriptions, lack of flange-back value of 0,5mm makes it impossible to focus on the infinity point if used on 44,0mm Canon EOS Digital mount, so most of superb Minolta SLR lenses while silver salt film period are deserted as voids in the market, but actually they are all available if tried to adjust for matching the different construction on flange-backs each other. This kind of hobby works on lens adaptations are not guilty, because the work itself is not destructive but constructive to survive the lives of wonderful industrial products like a phoenix. I should not be denounced but be appreciated.

Iga-Ueno & Shigaraki

I happened to come across with a wild fox in the mountain at Iga-Ueno city, it might have been nourished and fed by someone because it didn't try to run away if it recognized me at a distance. It was an unexpected good opportunity to meet with a wild animal, I did not have such a chance if I didn't get into deep in the mountains.
On the way of Western Meihan Road to Iga-Ueno at Kashiba parking area, a very rare historic old sports car, TOYOTA 2000 GT was there, even now it looked so sophisticated that may be available. Shigaraki was not crowded because of week day. Heavy rain fall the other day carried much dust on the artificial pond "Amagase" along with Route 307. Basically, prefer I a natural circumstance in the country side to artificial ones in the city.

Differences

What is the apparent difference between the conditions before adjusting and after establishing "Zero Thrust" in a vehicle?
The frequency of steering adjusting by the driver remarkably reduces to keep straight running.
Running direction is not changed by an ordinary noise stimulation from the ground rough condition.
The centricity of the car and that of the driver match firmly each other leading to an ultimate fun of driving.
As an only drawback of "Zero Thrust", the driver must be caused drowsiness as a matter of fact, probably because some lack of concentration to keep straight running, the vehicle goes straight without adjusting and a fundamental character to keep the continued stable condition.

By the way, we should know the difference between the rough ways to spend plenty of money relying mainly on debt and some elegant lives with principles.  Such kind of dignity as a human-being is nourished in a short period time in US, however worthy in bulk there might be?

Thrust precision

Plus 1,190 minutes of thrust angle discrepancy in VW1302 Super Beetle was corrected into zero condition after several hundreds km break-in of rear torsion arm rubber bushes replacements. Only an initial adjustment of wheel alignment and constructive axle geometry is not enough to establish a good alignment condition for all the vehicle on earth. According to my experiences, several times of adjustment should be repeated till all the deformable parts would be completed their plastic deformations promptly.
It goes without writing that the scaling and the adjusting procedures should be performed under the same condition with actual driven phase, so 60kg weight as a driver's body should be put on the seat position if the actual probability is so. 

Adjusting compliance

As I mentioned before, additional 3mm thickness rubber sims would be applied into the IRS construction of VW1302 Super Beetle to prevent too much lateral direction compliance, red marked positions as shown. This kind of trifle idea to set rubber sims here should be effective to attain natural steering reactive performance especially on the very initial beginning stage of the action. In another words, the displacement of the rear axle construction does much harm on the steering actions, makes it muddy, sticky and dull. Preventing this inconvenient displacement of the construction to lateral direction, some astringent, cool and comfortable steering reaction would be acquired. The rate of compliance and balance is the most nervous point and the most important proposition from the old days for the factory designing engineer. It must be the truth that the compliance application onto the points are the key to success to accomplish a good and comfortable ride of my Super Beetle.
JIS #70 hardness with 3mm thickness rubber material would be tested as an initial attempt for my interesting experiment.

IRS lateral displacement

VW1302 Super Beetle has been operated on IRS trailing arm bushes on both sides inner and outer and the steering action was far improved comparing with before operation. But, I'm not fully satisfied with this improvement because the very initial phase of steering action is still dull and muddy for me, this phenomena is not caused by the tire profile 80%, weak spring and shock absorber, narrower tire tread but the lack of the resistance to an inconvenient lateral displacement of IRS trailing arm. #70 JIS rubber standard 3mm thickness round doughnut shaped parts would be applied between trailing arm bracket and IRS bush outer end surface promptly. This method for preventing the arm from lateral movement is commonly used in some Motor Sports field, for example, TRD special parts for the purpose on NCP 10 Vitz Cup Races. The result of this experiment on VW1302 Super Beetle would be reported later.

VW1302 Thrust adjusted

The thrust angle was adjusted to the nearest condition of zero utilizing DIY special tool that has a LASER pointer in the level body for the checking of horizontal wheel inclination and 1719,75 mm radius pendulum device for doing vertical wheel inclination promptly. As a consequence arising along with IRS arm bushes replacement performed the other day, thrust angle adjustment is one of an indispensable procedure for me. The angle rate value of discrepancy before that was plus 2,37 minutes angle value that is acceptable value referring with European Traffic Safety Standard plus minus 10 minutes.
In order to establish "Zero Thrust" condition in Air-cooled VW 1302 Super Beetle, very special technique was required, because just loosening the axle bolt connecting trailing arm and hub bearing case loses rear body height in a few centimeter, so the supporting point should be set not on the shock absorber portion but on the tip end of the arm avoiding assembling error. Though I have been imagining that some unstable steering reaction such as wondering on a rut road should be brought by too much applied compliance especially to horizontal direction, it was proved after the adjustment that my idea was not to the point.
Basically fluffy as the 1302 genuine suspension and axle construction is, this is not the reason for unstable wondering at all, it goes straight in a great peace like an arrow flies after obtaining "Zero Thrust" condition. However hard I might try to find disadvantage to do like this, no argument occurs in my mind, a rolling frictional resistance and slip angle might be kept in the minimum conditions leading to compensating fuel consumption as a matter of fact?

VW1302 rear axle operation

I applied serious operation on rear axle of VW 1302 Super Beetle yesterday. They were IRS control arm bushes those had not been replaced from the beginning 42 years ago. Though the replacement rubber main parts, 4 pieces of bushes had been prepared two years ago, they were left undone because a very important information about the procedure could not be obtained, how much angular action would happen when the trailing arm movement stopper might be released. Also, the owner of VW shop in Takarazuka Hyogo Pref. was not so friendly as to tell me the data about that because of his selfish dealing strategy, it goes without writing here that I stopped to drop on him after that. On the other hand, YouTube movie information about the action of the torsion bar spring construction after releasing gave me an enough confidence to proceed to an experienced dis assembling procedure. Recording the original angular position of the torsion springs is the key to success, but for that, it would take time to find out some balanced adequate positions of them. And newly applied rubber parts prevented me from tightening the cover plate, the countermeasure to put new bushes on an adequate positions was preparing some longer stud bolts and nuts. Now, all the inexplicable part on VW1302 Super Beetle has eliminated thoroughly.
