Found this video about printing 3D parts for a motor etc. But having no access to a printer I am hoping some one here can tell me where to have it done? And are there any plans for a large 7 to 10 inch belt pulley that will bolt onto a hub, already available? The hard part would be to make sure it will fit in the right distance from the hub. And it would need to be printed in four parts then bolted together, to get around the brake rotor mount.
Note how this bike has no rear brakes at all:
This does not seem to have what I would need: https://www.thingiverse.com/thing:16627
I assume that I can buy small factory made pulleys for the motor.
If I could have it fit this sprocket holder, every thing would be copacetic. http://www.mmbikeparts.com/Sprocket-Ada ... l-only.htm
Actualy I don't think that adapter will fit my hub. So the pulley will have to bolt onto the back side of the rotor mount.
The newest windows 10 has a 3D builder, but it does not already have the right shape. And I have no idea how to make it. Some one should make a file of a 3D timing belt pulley. So people could change the size to fit their need. But I think this 3D builder is only for playing with the 3D effect.
