I don't know if anyone has a 3D printer on this group, but in case you do (or know someone that does), I modeled all of the gears, the keyed hub, banjo, lathe handle, and a transposition gear for my Craftsman 109 lathe and posted them on Thingiverse:??
I have included all of the STLs, DXFs, and Autodesk Inventor files for each model in case people want/need to edit the files.? I licensed everything under a Creative Commons - Non-Commercial - Share-Alike license meaning anyone can share or use them but cannot sell them:??
Enjoy!
