Is there any compatability among other sb lathes? My series and size ( 1928) seems to be fairly rare, if not could someone help me with the specs so i can cut my own? Heck it would be a great project for my new indexing head :)
Thanks!

You can tell us and yourself what you have

Any change gear known to be for your lathe you do have can be measured

Count teeth

Add two to the count

Measure OD with mic

Divide that O.D. in to the count plus two

Example:

32 teeth, 2.125" O.D.

34 divided by 2.125 = 16 diametral pitch - often written 16 DP
 
I have an 11” 1922 27-B that I’m in need of some gears also. Are you looking for certain ones or all of them? I know that mine have an ID bore of .625 and keyway is .19 wide. Thickness is also .625 but that is as far as I’ve gotten on figuring things out.
