6201 Pillow Block Low

I don't know how useful this is going to be for you but I find 6201 bearings fascinating as they are very low cost and can be easily made to fit a 1/2" shaft by reducing the ends by a very small amount. I've built an attachment to my angle grinder that takes off the smallest amount and locks the shaft in place. If I need more strength I double these up. Someday I'll remake these out of metal but right now all I have is a 3D printer and some basic hand tools.
