Atlas 10100 cross feed set screws for the two indicators - sp?

[Craig Parkinson]

Has anyone encountered problems keeping the set screw for the indicator for the cross slide and compound rest from turning after you have tightened the 3-32 set screw? I cannot get the set screw to stay in position due to all the oil in the screw threads. My plan is to use the weakest lock tight so it stays in position so I can zero it when needed.

Ever thought about a wrap or two of teflon (PTFE) tape on it?

An old trick used for fixings in high vibration areas. Whether it was Screws / bolts/ nuts it held them in place well enough.

I had not thought of that. I’m going to give that a shot. I have the tape. I’ll let you know how it works. I’ve got a little project coming up where I need to be able to set the dial to zero to concentrate on turing my backing plate as accurately as possible to fit my new 4” chuck.

I think I put a piece of copper wire in the threaded hole and tighten down on it for the cross slide. I don’t use the compound for anything but tapers. My compound leadscrew will start moving on its own if any resonance kicks in. So I just have a habit of holding onto it. Lol

I just tried that a wrap or two more like 3 in my case. Ill do it again with 3 wraps and a small piece of copper wire for the bottom of the hole. Thanks again.

Thanks. I did the two wrap teflon tape thing. It needs 3 wraps and a dollop of copper wire for the bottom of the hole. Thanks for the suggestion.

Thanks. I'm going to do the teflon tape and copper wire trick. I did wrap the set screw in two wraps. Neds just one more and the copper wire. Thanks for the suggestion
