Partial wiring diagram showing the high-voltage cables
The big green box in the middle is the "hairball" unit for the Zilla 1K main controller, and the board to the right of that is the battery regulator. The Arduino (which might end up being a Raspberry Pi with a servo board, I haven't decided yet) will be controlling the cooling fans, cooling pump and motor advance servo.

Finally back to work with the help of my friend Jean-Pierre
He's an expert metalworker
See the installation he did for the 12V servo that controls the brush advance

Brakes and Floor Panel

Wheels are compomotive CXR 13 inch, 5.5 wide in front 6 on rear. Brakes are Hi Spec, 4 piston front and 2 piston rear. the rears have an integral handbrake mechanism on the side, with dedicated brake pads. The rear installation is a bit particular: the discs are from a citroen AX, 238 diameter, redrilled from 3x98 to 4x108. The ford fiesta hubs were turned down on the lathe so they could fit the discs, and the disc center hole was turned also on the lathe to fit the 63 mm fiesta center. The combined weight savings of using an AX disc and turning down the hub is over 1 kilogram per wheel as compared to a standard fiesta hub & disc.

belt drive assembled

Here is the belt drive final assembly, with the belt in place. It has not run under power yet but spinning it by hand it is extremely smooth with no tight spots or jolts. It feels like gears running in oil.

belt tensioner trial fit

Many thanks to Marc and Robert of the Dassault Aviation model club for their help machining this part on the lathe. It's eccentric mounted, the bolt you see is 6mm off center relative to the axis of rotation, so by setting the position of the central hub you can change the belt tension.
