Running straight, possible?

It was always something I admired to accomplish it since I was a young guy to adjust my own automobile run straight without any strange lateral bad habit. There are steering reaction habit tendency to go right or left, then there may exist to run straight keeping centricity?

However often I may visit maker's factory to eliminate bad habit with lateral steering tendency, I had never been satisfied with their reactions.
The author of famous "The actual wheel alignment adjustment" could not be performed on my requests, in spite of the adjustment by himself using Sun Alignment Tester made in US.

Because nobody could do on wheel alignment, I made up my mind to do that by myself with some serious determination, "Never turn back until I would succeed in the attempt, no matter how I might have cruel experiences were waiting for me." That was about 10 years ago.

According to getting accustomed to the construction of an automobile gradually, I could come to be capable to maintain almost of maintenance schedules by myself except a motor and trans-axle taking down works.

Uncountable trials were attempted to create the measuring devices for toe and camber scaling with repeatability in addition to seeking and deciding the unmovable scaling null measuring initial points.
Devices were tried so many time to establish the scaling repeatability and to obtain also repeatable datum.
For toe measurement Laser pointer equipped ground level meter were utilized by connecting adapters on the standard flat surface on it.

On the other hand,1719,75mm radius pendulum mechanical device was invented for scaling the wheel vertical inclination, camber value as precise as possible.
The radius should be extended without restrictions if the scaling accuracy is desired, but the height of the ceiling of the garage and the convenience to read the angle value 60 minutes per 2mm, so the radius length was decided.

The technology in model flying aircraft construction was invited on the devise for vertical inclination instrument, fulfilling the requirements that lighter as possible with adequate strength with the physical property not to be distorted for keeping accuracy.
Also the calibration technology of the devise was ultimately necessary to establish the datum repeatability.

Additionally the standardization of measurement conditions were above words of difficult, because it had been taking time jobs to find out and to perceive the cause of errors that had been suffering from scattered datum value, affecting on the reliability of the research.

The physical property of butyl rubber was the strongest enemy for me, applied every where in suspension arm bushes and insulators, viscoelasticity, deformans and hatred hysteresis.
Also, the viscoelastic lubricant grease on radial bearings and ball joints in axle construction could be some artifacts.

The datum obtained were analyzed by means of statistical methods by the professional in mathematical division in the University. The reliability of the datum should be obtained in correct sampling manners and be analyzed in adequate methods.

Just doing something is relatively easy as some single attempt, but the accomplishment of the work fulfilling several requirements scientifically, tremendous and desperate efforts for long time are required on earth.
