Dave forgot to send this to the list when he replied to me so I'm forwarding
it to anyone who's interested

Dave,
I just measured the ID of my old timing gears with vernier calipers - I
don't have an inside mic and my shafts are in the engine.
Crank gear ID is 1.375 inches,
Jackshaft gear ID is 1.105 inches.
I'm not sure what you're looking for with the 0.561 inch measurement. If
you mean the thickness of the gear I got 0.612-0.614 depending on which gear
I measured.
Let me know if you need more. If I get a chance next weekend - won't happen
this weekend - I can mic the nose of Woody's shafts. Wow, that doesn't
sound good does it? Anyway, his engine is apart and I've got a set of mic's
if no one else has come up with the measurements by then.
By the way, this came to me without the list being cc'd.
Hope that helps,

Subject: Re: Timing gears..get the calibers
Bingo!!! thats just what you need to search the available hardware in the
industrial world.
Can someone tell me the shaft diameter of the jackshaft which the 2
jack sprockets go on and the diameter of the crankshaft where the
crank sprocket goes on?
A 3/8 pitch chain is a #35 chain
Both my Martin and Browing catalogs list the sprockets with a minimun
bore. (Like a sprocket blank with a minimal hole in the center.)
The catalogs area listing these sprockets as 0.561" wide from outside of
tooth to outside of tooth. Can someone verifiy this?
Can someone communicate with me who has a used set of sprockets
and calibers to read dimensions?
If the crankshaft diameter is less than 1.3125", all but the cam sprocket
may be relatively easy to machine from stock sprockets.
Thanks,
daveS
