That turned out nice rleete. Was the socket a bugger to machine?

Not really. I think only the socket end is hardened. The worst part of machining off the drive end was the square hole and the interrupted cut. It parted cleanly and easily.

The side hole for the handle was drilled with a center drill. When I went to enlarge it slightly with a regular drill, it chewed up the bit. I think the hole hit the edge of where the socket was hardened. The center drills are just enough harder to work, whereas the cheap twist drill was too soft.
