4 Hour Bruder Dozer

[Ben1272]

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
