The device for measuring vertical wheel inclination was created by self-invention and innovation utilizing some adequate light wood material inviting the technology in Radio control model aeroplane construction with physical property of preventing distortion.
Hard disk drive plate is used as the absolute datum plane of the device.
Vertical continuation of this plane with 1719,75 mm distance is the center of the pendulum.
Horizontal continuation of the plane with 150mm distance fits on hub outer circular surface.
Though some popular coffee can is utilized as the horizontal adapter, the height with parallelism is calibrated by measuring with micrometer device at 10/1000 mm level.
On the other hand, horizontal scaler to measure toe values was prepared utilizing horizontal level meter with bubble position display glass tubes in two dimensions in addition to LASER pointer.
The level meter was recalibrated by disassembling glass tubes and by resetting firmly with accuracy in relations with own datum plane in two dimensions promptly.
Also the calibration was performed with LASER direction in relations with own datum plane by extending the scaling point to 10,000 mm.
The adapting point is not circular but two lines on 3 and 9 o'clock position with cylindrical shape, because of the convenience for keeping the device in parallel to the ground.
