I just received my new acme thread from Roton I machined one end for about 4" till the threads where gone. I then took a piece of 7/8 stress proof shaft and bored it slightly smaller. I then heated up the stress proof shaft untill it expanded enough to slip over the now machined threaded shaft after it cooled you would have to machine it to get it to come off but to be safe I drilled and reamed for a tapered pin. I then machined the whole thing down to the proper dimensions. I will now cut off the screw to the proper length and machine the other end.
I will then make up a jig so I can cut the keyway the full length I will keep you updated. Ray
