@specallez - I used a brass air fitting and drilled the center to the right size for the crank, then I used a die to create a thread. I then drilled and tapped the hex/nut part of the fitting for a lock screw and ground off the old tapered thread from the fitting. It was a male Jamec Pem air fitting
I've done some fine tuning to it now and got at least another 100 RPM, tacho on its way!
