I really hate it when I use a lathe as a welding jig so I thought I would do something about it.
I decided to make this with a hollow tube (88mm I.D) as it should make it quick and easy for welding flanges onto shafts,
the hole in the shaft/faceplate will be fitted with a removable bush/plug when the big hole is not required and can be made to centre small jobs.
The front and rear bosses will have 4 bolts in them to centre material in the tube in the same manner as a 4 jaw chuck,
I have fabbed a face plate that will be welded the front boss.
The tube will rotate within 8 x 6204 brgs, 4 at front and 4 towards the rear, think pipe roller, and a couple more
for thrust, rolling on a disc.
Yeah I know some will think that is rough but that is what I have got and it won't have much load on it and
it only spins at low revs anyhow.
I was just going to use a toothed belt drive reduction to the shaft with a speed controller http://ift.tt/1Mz6wI8 but it needed a bit more gear reduction as at very low rpm the motor was a bit weak, so with the change of plans it will now also get a neutral position and a shaft lock by sliding the gear set out of mesh.
I decided to make a gear reduction out of Briggs & Stratton camshaft gears, I was going to press the ring gear onto the boss with some loctite, I'm having a bit of a brain fart about this ?
Both parts are machined to 3.700", I wanted a light press fit but now I don't think that is a good idea as the ring gear is CI and
could crack, so what is the consensus about how much clearance I should give it in order for the ring gear to be slid onto the boss and be retained by loctite alone ?
