Fixed cup removal (with pics)

[Woz]

Yeah - that is last resort option. Haven't welded for years but could find someone in the village to do that and help.

The closest tool I found is this for old Solex front wheel drive scooters. Only in 37mm.



Now wait for it, go to the fridge first ....... this fixed cup of course just happened to be 38mm.

File 0.5mm off all the cup faces, or grind if you have a "delicate touch"

This will have the added benefit of removing some of the pointless, counter productive chamfer.
