First step was to remove the point cam and grind/file it down as round as possible. Couldn’t use a cutter on the lathe as this part is hardened and precision ground. Once reasonably round, I make a somewhat thin brass bushing and pressed it over the old eccentric area. The bushing deformed to some extent, which is what I wanted. Then I mounted the part in the lathe and turned the bushing perfectly round for an interference fit with the reluctor. Some people use epoxy to mount the reluctor, which might be perfectly functional, but you know I don’t glue things together in shop!
