That’ll be workaround number 1 until I can get some lathe time.
I’m not overly keen on doing it that way because an unthreaded sleeve will create one of two problems:
1. dig into the threads and get stuck if I use brass, copper or aluminium making it very difficult to remove the flywheel; or
2. Damage the threads if I use steel.
The other option is to make a loosely threaded sleeve that’s temporarily glued to the cup itself. That’d be much easier for me to make here than the whole nut with the shoulder.
I really should just go and see my friend with the lathe. I’ve made shouldered nuts before, it’s not difficult, just time consuming from here.
