Accuracy in Wheel alignment




In wheel alignment adjustment procedures, the value of camber angle is difficult to be measured and to be adjusted firmly and evenly on both sides of the vehicle.
Ordinally the special tool is utilized to know the vertical inclination, camber, but the reading the buble position in convexed glass tube method is far from accurate measurment. This unreliable tool used from long time ago made it difficult to measure and to adjust the camber value on earth. In addition to reading difficulty, the fixation of the device is unstable, because magnetic construction is equipped on the combining surfaces with the wheel hub. And the distance of the measuring points, hub diameter are around 55mm, it's too short to obtain the datum with accuracy and repeatability.
I just imagined to amplify these hub diameter's two points to utmost length till actual measurment phaze, to 1719,75mm multiply 2 diameter with mechanical pendulum construction.
Deeper considerations later.

Oil reserver and filler is hand made this morning. Processes photos shows every thing without any explanations. Small plastic piece end is remolded by heating.

My girl friends hesitate to introduce me to their another friends, because suddenly I say so straight not with along ordinal common sense.
They do not want to put themselves in such a situation to be with their red faces ?
Next I'm going to consider about this critical problems.
