Hi, Jan!
I got the rear gears you cut for me micro-polished and coated with tungsten sulfide to reduce friction. I'm waiting on the delivery of one needle bearing, then I can put it all together with the hybrid ceramic bearings, lower-RPM clutch springs, and taller rear gears.
Shouldn't be long now, I hope.
I'll have to email you about the camshaft grind, as well.
Can you do rim fabrication? I'm going to order the sprag clutch soon, so I can mock up the rim offset... if I can't find a CNC machinist who can fabricate a new rim for me, I'll go with Christ's recommendation, buy a new rim, cut the center out of it, weld in a solid disc, and cut the holes for mounting the sprag. I'll have to hire it done, as I don't have aluminum welding abilities. The only thing I'm worried about in doing as Christ recommended is the durability of the welds. I'll also have to figure out some way of affixing the sprag center hole to the axle... the axle is a splined type, whereas the sprag has a keyway... so some sort of bushing and some means of locking it in so it can't move axially.
