Contact wheel... help in Knife Making Posted December 4, 2009 Alright, I need a 10" contact wheel for the grinder that I am working on, but I am pinchin' pennies. Does anyone know of a cheeper alternative with close to the same quality? I've checked out polyurathane, but I am afraid that it will melt or wear to quickly. I've also looked at the grizzly 10" contact wheel, but I need one with bearings. So, I would love to hear your advice!
