I'm looking for a 3/4 or 1" 10 turn acme screw 6' and an anti backlash nut. I just don't want get into ball screws prices for acme gear. Mcmaster-carr isn't too bad on the screw, but I was hoping to find a source of anti backlash nuts in the price range of dumpstercnc or cncrouterparts. Does anyone have any recommendations? If not a cheaper source just knowing you are happy with a particular anti-backlash nut would be useful to know. Thanks!
