The most common methods use something that expands into the HS bore,
attached to the actual handcrank. One style uses a diagonally cut
piece that expands into the HS bore when it's tightened; exactly like
a bicycle handlebar adjuster. The other style uses a double-
expanding concrete anchor to grip the bore. You'll want about a 6"
lever arm with some flavor of knob. If you can get one, an old valve
handwheel works nicely, as does a defunct ball joint in a piece of
flat stock.

Does anybody know a procudure how to make a handcrank? A while ago
I ran
across a procedure on one of the lathe/minilathe/machining
websites. But I
do not remember any more which website that was.
Thank you.

The handiest threading accessory you can make is a handcrank!
Particularly on short, shouldered pieces turning the lathe by hand
gives more torque & much better control.
