Well, I'd certainly like to get a hold of a 47 and 53 tooth
combination!! I'm not even too fussy on bore hole size, I'll just make a
bushing.

these gears have TAPERED center holes; approximately:
1 7/16" - 1 11/16"

about 1" thick

as an example the 47t was about 6 1/8" OD, the 53t about 6 7/8".

Sounds like those are diametrical pitch 8. Those are BIG gears!

An even Better combination is a 80/63 combination, easily made from
smaller gears in a compund train.
The 80/63 breaks down to a 20/21 * 4/3 combination. Finding 20,21 4:3
tooth gears set might be easier, and is More Accurate.

47/37 = 1.27027
80/63 = 1.26984 Much closer to 1.27 !
