Pembroke:87Percy’s New Wheels
There is a little progress each evening toward re-wheeling and re-motoring Percy. The old wheels proved remarkably robust when it came time to disassemble them. Assembled with one of the red LocTites, the only way to get them apart was to break the plastic centres. It was a savage evening!
I printed new centres, and then found the orientation for the axles that makes the two slots line up. I want to avoid solder on the steel tyres this time, and so, I’m using a shorting wire that makes a mechanical connection by being trapped in a groove against the tyre and axle.
Things were going swimmingly until I tried mounting some of these wheels on the axles. Two were nowhere near perpendicular to the axle for some reason, and a third was so badly out of quarter, it completely crushed the key. It was at that time that I decided to take a break and start the printer going for a new set of wheel centres. Maybe tomorrow I will have skills!
All the parts ready to go. The tyres are reused, as is the plain axle.A dry fit test of the shorting wire.One wheel was so badly out of quarter, I crushed the key while mounting it.
