Re: A new shift concept for the engineers....
I did manage to get over to the metal drop center today.
I bought a small sheet of 11 gauge, (.115"), 304 Stainless Steel...enough to make 9 sprockets of various sizes.
I sheared it up into the appropriate size squares for sprockets.
I had planned on getting them into the machine today, but ran out of time.
Tomorrow I should have the three clusters finished. (2) 52/48/44 & (1) 44/40/36 for my own use.
Even if I have to make some sort of deraileur type mechanism...I'm sure this is going to work.
Practical? Affordable? I seriously doubt it. If the sprockets could be made cheaply...it might fly.
I have tried both a waterjet, and a laser for cutting sprockets. Neither process is accurate enough.
A wire E.D.M. would be accurate enough with the benefit of being able to stack and cut 20+ at a time.
Cutting steel sprockets on the mill is just too slow to be practical. I cut all of the sprockets for the Spoiler build...It takes 3X as long to cut steel sprockets of the same tooth count in Aluminum.
