In this video we start the machine work on the threaded screw and three nuts needed that are used to hold the vertical head onto the parking attachment. I use some 1141 Stressproof cold rolled bar stock to machine the screw. We'll be indicating, turning, and threading in this one.
In 14 Part 2 we'll finish the threading, and mill the hex. We'll also do some modifications to some NOS brass hex nuts from my old shop stock.
