So here is what I have been doing. I 3D printed a little piece that goes over the CTP which has an 8 meter sting attached to it. the other end of the string attaches to the device the MTV is placed on. Basically it is a long band of acrylic with two little things that flip up and hold the MTV. Then there is a caliper with one side attached to this acrylic piece and the other is free to extend thus creating an angle with the acrylic piece and the other arm of the caliper which remains on the center line drawn by the sting. The measurement we put on the caliper dictates the initial angle. Also, if you draw the track in AutoCad and draw a circle that touches the VSP, CTP and any desired VTP, and draw a tangent to the circle at the VSP you can measure the angle between the center line and the tangent line which would yield the theoretical initial offset angle for the interval to which the circle corresponds. Of course this is just a theoretical angle and you may will probably have to change it to compensate for over/under steering. Hope I helped.
I build. A lot.
