Darwin's X-axis toothed pulley
The last gear problem for Darwin, casting a 12 mm gear to fit on a 6.35 mm motor shaft. A flat was needed to ensure no slippage on such a thin shaft. Final solution was to use the same kit used to make the Y gears (see previous post). The collar was prepacked again, but this time, becasue there was a bit more wall thickness, the hole was simply started by working a screwdriver into the capa. The collar was then put into the pot with a new blade part which fitted the motor shaft profile. The motor shaft was then poked in from the back. Worked first time.
This was then complemented with Vik's superb idea of a washer + bit of capa for the second lip.
Next: a repeatabiltiy test for the X. Though I need to solder up a universal PCB first...
