Improving the RF-30 Mill/Drill Y Axis Take Up Nut

Paul,

Your suggestion of increasing friction on the screw is a good one. I have played with RTV many times and found it does not hold up well around movement. Using a strip of nylon is far more robust. Someone suggested using a Belleville washer between the parts and that would work too. Using split washers would not be good because of the uneven force. I'm wondering if rubber O-rings might provide enough pressure on the parts to lock in the screw. These O-rings only need to provide drag and will not see any leadscrew force.

Thanks!

Rick
