    Default change gears for series O 11 inch?

    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.

    Keyway is more likely .1875" wide, or at least started life as such.
