Hand spindle crank for 9x20 lathe wide shot of the hand crank installed into the spindle of a 9x20 lathe.
That's a ball bearing assembly used as a speed knob for turning the hand crank with left hand.
Manually turning the lathe spindle for turning short sections of threads near a shoulder, where power threading may lead to a crash.
Shop-made project cold rolled steel and a cast aluminum handwheel locks into the spindle by carefully tightening the nut at the center of the handwheel.
I got the idea for this sort of locking joint when I recalled how my old bike handlebar stem was secured in the forks tube.
