Percy and the Driver Test

I’m nearly ready to go ahead with the “final” set of wheels for Percy. These will feature a combination of keys and Loctite to ensure everything goes together in alignment and, more importantly, stays that way. The 3D printer makes test fits unusually easy, and so, I’ve broken from my damn-the-torpedoes tradition, and made a test fit of all the parts. Disassembling the drivers will destroy the centres, but, their replacement will be a simple matter.

The “final” wheel plan for Percy includes turned tyres pressed onto printed centres, which are keyed onto split axles. Shorting strips soldered to the tyres, will provide electrical conductivity.
