Most vintage K & T Horizontal Milling Machines are missing the all-important drive gear for the vertical/universal head. The drive gears are rare to find just like K & T Model 2D collets. My K & T Model 2CH Horizontal was no different.
Ramsey1 was gracious enough to machine me a 30 Tooth helical drive gear for my universal head with quill adjustment. It was only the gear without the drive lugs. After careful analysis, I decided to reverse the drive lug concept and make special spindle drive keys and mill slots into the gear. Please see the attached photos.
The drive gear, round plate, and threaded lock bolt, were mounted to a NMTB 50 Taper tool holder. The special drive keys were mounted into the spindle. So far, the gear fits, locks into place, and appears to rotate without much runout.
The next step is to mount the heavy universal head, test the gear mesh, and actually run the universal head spindle. My 2CH does not have a parking attachment, so mounting the universal head will be a challenge. I still have to finish one (1) spindle drive key for the head spindle.
