Now it's summer 2024 and I am keen to
get the little red car back in shape for *this* year's
Microcar event.
I have, on hand, swingarms and a differential from a Ford Think NEV. The good part:
- same tire diameter (despite different rims, and the need for spacers)
The bad part:
- to go 50 mph, the input to the diff would have to be ~13,000 rpm (because the Think diff has a 10.5:1 ratio)
SO! The plan is this: Buy a BMW 5-series rear differential ($140 with shipping on eBay. Amazing! btw, about 3.5:1) and use my Cushman Truckster transmission (a veteran of microfurthur, my three-wheeled Lambretta conversion) and the D&D shunt-wound motor (10 hp continuous, 30 hp peak; same as before) motor.
Maybe... more later.

Think swingarms, BMW differential.
