It's Alive. Have resurrected the belt drive rickimbili.
nearly gave up and bought a GEBE kit, but my stays
are too narrow for the kit among other issues.
Sooo... I hand tooled a new shaft and reconfigured
most everything which, to my delight, performs better
than i could have hoped. The stealth tour bike rolls
once more.
Looking at the picture of the Whizzer or Whizzer Clone type sheave on the rear wheel, I was wondering if I see where you cut and rewelded to widen the rear stays.
I have my home made pulley split as it was just a cast aluminum washing machine pulley and forgot that 40 years ago the same part was of pressed steel.
I ended up getting a Whizzer sheave clone part as it is made of steel, but the thing sticks out side ways so much it needed the stays widened.
The kind of smaller pulley that the way I mounted it much closer to the spokes and has more clearance to the stays, I looked and could not find in steel any more.
Cast iron is strong, but my method of cutting the bore out and bending the arms just slightly to match the cone shape of the spokes only works with metal that keeps at least some of its strength when bent and does not crack.
Cast iron is brittle and would crack unlike steel.
I found that people can cold bend or just spread the stays each time and use a longer axle. Just there are limits to how that would work. It was OK with my old setup as it only needed about an extra inch.
Now I think I have to cut and re-weld to spread the stays properly. Other way I thought was just to make a rounded notch where needed and leave the axle the same length. Then the sheave , belt, and the tire will clear the stays.
Any thoughts, also maybe such as that I could modify the clone sheave to be closer to the spokes.
