With the nuts and all-thread mounted in the chuck, we're ready to turn
down 0.200" of the end until it just fits in the head. Notice that the
slits in the nuts are between the jaws. When I got within 0.004" of the

advancing by 0.0005" (which reduces the diameter by 0.001") and checking
for fit each time.
