Re: Engineering Project on Mecanum Wheels-Please help me gather input
We have built mech wheels using 3/4 HDPE, Rubber stoppers, long 1/4x20 bolts, and brass bearings. We cut the HDPE (high density poly ethalene) close with our ban saw, than lathed it to round. We than set up a jig and using a drill press we first drilled at a 45 using a 1 1/8 paddle bit around both sides and than drilled though with a 3/8 bit for the bearings. If you use a long 1/4 x 20 bolt you can bottom the nut out just shy of the rubber stoppers.
