Reg, do you think plastic sprockets could hold up for use with the #35 roller chain based tracks? I can design and print them on my 3D printer in ABS plastic or PLA plastic, which is a bit harder than the ABS. Will sand, etc., just wear them away prematurely?
I think I am going to give it a shot and see. Can always convert to aluminum if it is a no go.
My aluminum extrusion is due here any day.
Thanks for your help,
Ben
