For the bearings of a little generator/motor, the same steel as the shaft, unhardened would do, it only has to take off .001" or .002", and probably only off one bush, job done. But it would be worth hardening and tempering the reamer, and put it away carefully, and in years to come you can make another one "cause you can't remember where you put the first one, it will turn up just after you finish with the new one Ian S C
An open frame generator with a solid state regulator is a real technology clash.
Next thing you know you'll want to use LEDs.
And by the way, you can call it bubble, it's still big. Streisand once said; " I'm a curvy gal, it starts at my nose"

But if I do...yeah, probably a voltage regulator and an LED. Was that a decision?
I had drilled/reamed the hole 1mm undersize. Too much for a press fit? Should it have been .5mm?
