Did you have any video how to prepare the polyurethane? I need to make a 75 duro split neep for a feeding machine in yellow urethane, is something that you can do?
what turning tools did you use? i'm making 38mm diameter and 13mm thick wheels, and it's a nightmare... i'm using a polished carbide cutter, used by the automotive industrie to cut plastics with... now i'm thinking of mounting the cutter in a routher and the router in the toolpost... so i rotate the material and mill it with the router... it's giving me nightmares :D
