    I decided to make a couple of square head bolts for the clamp bolts on the stop instead of using commercial socket head cap screws. This video covers order of operations, working with multiple parts and turning and threading the shank. The next video will cover the work on the head, including cutting a radiused bottom groove, a large spherical radius on the ends and squaring the heads. I’ll also show how to heat treat the bolts to Rc60 to make them stronger and more durable.
