I think your 'Count Scapula' handle is very hip. More pressure to make ss could be had with a hydraulic press. Using a hinge on the die is ingenious. Bottoming taps have flat ends and are manufactured specifically for chasing threads but being super hard can break off and cause heartaches and headaches. Also, an old socket on the end, instead of the handle, would let you use a breaker bar/t-handle, or even a ratchet. Thanks for sharing your ideas.
