I'm fixing up an old Starliner GEM.
It came with a 5 1/4 " worm gear on the shaft, but no external clutch/brake attachments(just a pair of threaded holes on the top and bottom hubs of the gear itself).
I'm thinking of anchoring 1/2 of a 2 piece shaft collar to the hub of the worm gear with a bolt or set screw.
I could then clamp the worm gear with fewer, more accessible set screws or shoulder screws with plastic knobs attached.
Q1: I was thinking of drilling the pilot hole in the collar 1st, then using that as a guide to drill pilot hole in the gear hub itself, with both collar and gear clamped to end of the dec shaft. Sound like a plan?
Q2: Do I need(and how) to shim the "fixed" half of the collar so there will be clearance to rotate freely when disengaged?
Q3: Obviously, I'm not an experienced machinist, is this plan feasible?
Thanks
