A little side project for my personal car. The CEAM push-to-start ignition switch was missing from my Lancia Flavia and I have been fortunate enough to acquire a parts car with a matching set of locks. So I set off rebuilding the ignition switch.
The original lock ring had been badly chewed up with a pair of channel locks. So we placed it in the lathe and re-knurled it.
A quick and dirty expanding collet to hold bronze retaining ring without damaging the threads.
By using a live center in the tailstock, we can apply pressure to the expanding collet.
Ready to be sent out for chrome plating.
