Had little down time this last weekend. I am still waiting for some tooling and parts for my other projects so i thought i would tackle this small project for another future build. crank started out has a hssk crank like my other project build,but i thought i would go one more step with this crank or i really should say multiple steps...lol . going to make a electronic ignition crank into a points crank.
first thing i want to do is just make sure my tapered angle was going to be correct by machine a piece of steel rod as a test run.
then clean up a old points hs50 flywheel and then some valve lapping compound on to the tapered end.
run the flywheel back and forth to see how it turn out. looks good. has a nice gray pattern on the end of it.
chuck up the crank and off we go.
finish taper. next step i will give it a quick polish.
next step i will cut down the old threads for the new smaller threads. yes the taper and the threads are smaller on the points crankshafts....nice. makes it easy.
cut the new 7/16-20 threads.
grab the old nut from one of my rupp cranks and thread it on to the new crank.
ready for some points action.....
