The final frame prep is complete for Alex’s dirt jumper. Made the arbor in the shop to accommodate the cutters and the lathe made easy work of the process. This cutter is for a 44mm headset.

Some recent goings on in the shop and in the craft room.
Practice Tubing Prepped
Dialed in the BenchMaster Mill and made a few practice pieces for Tig experiment. I am sure these will not look so good after the Tig experiment but looking forward to that just the same. These are 4130 straight gauge tubes 1- 1/8″ .035 wall notched at 90 degrees to to mate with 1-1/2″ .083 wall.

Sputnik Fixtures Dialed In
Sputnik Jig Setup
Experimenting with slotting tubing for dropouts on Sheldon Horizontal Mill. Vise allows pass through for stays and keeps various diameters centered on slotting saw. For tapered tubes the vise can be tilted to compensate and a round wire on the top of vee block makes for rigid setup.

Another view of slotting setup. Cut a bunch of straight 4130 to dial it in.
