Steve, thanks for the part numbers.
Google turned up zip on the worm gear, but found a Union Gear catalog online and the BWG-1120S listed:
Bronze gear, single turn ratio. 20:1 gearing
http://www.traceygear.com/UnionGear/Unio...atalog.pdf
1/2" face, 20tooth, 1.666" pitch diameter, 1/2" shaft, 1.25" hub diameter.
Gearbox... I used 90W, but have some OLD (like 40 year old) bottles of magic stuff (Molybdenum Disulphide) gear additive that I squirted in. Yep, bought four bottles for my '67 Datsun Gearbox... still have some sitting around. Never realized it would be a lifetime supply! :)
