Re: Cross Slide Lead Screw vs Brass Nut ?

Re: Cross Slide Lead Screw vs Brass Nut ?
A "Thread Restoring File" will do a better job of refining the threads than free-hand sandpaper. You'll need one that includes M1.0; should be available from a local auto parts store. Roy I since not

Cross Slide Lead Screw vs Brass Nut ?
As part of adding a ball bearing and more travel to my cross slide I removed the cross slide lead screw. I noted a sludge on the lead screw which looks like powdered brass mixed with grease. I suspect

Re: chuck holding power
Are you sure that it is not hardened? Some users have confused drill ROD with drill BLANKS. Drill blanks are hardened and can't be turned in the lathe. Drill rod can also be in a hardened state that

Re: chuck holding power
The chuck will improve if it's reduced to its component parts, deburred and lubricated. There's usually one jaw that binds against the body, reducing the clamping force. All that being said, drill rod

Re: chuck holding power
I was using a die. Single point is not a problem. So the chuck is simply not able to withstand the torque required for die-threading, is that it? 1/4-20 is a tough one, of course, I have no problem

chuck holding power
I tried to hold a piece of D size drill rod (.246") in the stad 3" chuck on my Homier 7x12 and cut a 1/4-20 thread, and could not. The rod would slip in the chuck, no matter how hard I tried to crack

Re: chuck holding power
If you are serious about this you could try turning a sholder on the rod in order to make the start easier. But what I would do is start the thread with single point then finish it with a die. Single

Re: chuck holding power
Hello Richard, A couple of things to look at: 1. I assume you are trying to single point the thread and not trying to use a die. Assuming that is the case start by checking how hard the drill rod is.
