I would like to put cnc on my little lathe as well and there I would need and encoder on the spindle and as of now I have no idea what that entails. Here is a little stunt I learned that might help someone else. I installed new lead screw on my lathe and cast a new nut from the piece of screw I cut off. Been using the screw for threading and feed for a couple years and it is holding yo well. A tiny bit of wear. I took the nut out and brushed a coat of epoxy on the thread let it harden, back to "o" backlash. Might help someone with an acme thread lead screw. :-) Just to give a little something back, Doug |
