Ursa,
While not convenient, I think you can still buy the parts needed to build the older style 8" AM mecanums:
- 1 bag of
rollers for the 4 wheels
- 8
plates
- 4 sets of
spacers
- (24) 1 /4” stainless steel washers, 0.04” thick per wheel
- (12) #10-32 x 3.0 inch-long screws per wheel
- (12) #10-32 nylock nuts per wheel
- (6) #10-32 screws and nuts to mount hub of choice - length depends on mounting
You could look into
this vendor as well.
Have you considered the
VEXpro mecanums?
Hope this helps. Let me know if there is anything else I can do.
