2dof plus traction loss platform

Hi everyone, this is my motion platform. I built a motion platform because I already had a race rig setup which is from pagnian imports. Here is the initial design, as you can see, as the build started, the measurements started to change as well, manly to get the most out the lengths of steel.

all the steel is cut and welded up(don't look to close, the welding isn't the best but it holds).

I used a old tailshaft as most people have for the pivot point. here is quick fit out.

Next is the wiring, I used 3 monster moto plus Arduino boards.
the heat sinks I had were to small, now they are twice the size and with fans.

This is the wiring diagram I followed which I copied from Andrea 1968.
Wired up and testing software and components. all working good.
Now tidy up wiring, fit plywood boards, paint, install in room and fit race rig.

Here is a test run in an F1 Renault crashing.


Ok here is some info of the equipment used.
The 3 motors are all the same(Worm Drive Motor 12V/24V 200W, 180 RPM, 20Nm Torque)
and are from motion dynamics, as used by other members. 12mm stainless fence bolt(flat head with square before thread used for attaching lever arm).
10mm to 6mm coupling, drilled out to 12mm-6mm to attach the 360deg hall sensor pot.
Rose heads and connecting rods are go-kart steering parts.
Race rig and belts from pagnian imports.
Monster moto boards from ebay user diybox. so far the 3 I have are o.k.
3 x 60Amp power supplies
3/4 inch pillow block bearing, 2 bolt for front traction loss pivot point

A couple of changes to make I think are the lever shortened to 60mm at the moment its 100mm.
Possible gearbox change to 60:1, I think the gearboxes I have are 20:1
