Has anyone used UHMW for their homemade plastic nuts. It seems to be about twice as slippery as Delrin, but is it strong enough. I'm going to try using 2 start 1/2-8 acme rod, and I'm thinking the lower the friction the better. Or what about Teflon filled Delrin. Although it's 3 times the price, this might be the way to go. Any opinions?
