We are in process of reverse engineering the taper on the end of the crank. We are building a electric start conversion and belt drive system for CNW.
We have used our CNC machines to get accurate (well pretty close anyway) measurements of the taper. We plan to make tapered blanks and "blue" the fit to insure correct taper angle and depth before starting production on the prototype sprokets.
All this being said, I was wondering if anyone out there had print dimensions of the taper (preferably the sprocket female taper, and not the crank male taper), both included angle and ID's at beginning and end of taper.
It would be nice to compare print dimensions (if anyone knows the specs) to what we get in our metrology analysis.
Thanks in advance
