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. Will a file cut it? if not then it must be anealed before threading. 2. Single point threading is done with repeated passes each slightly deeper than the one before. Your first pass should barely scratch the surface. There is a lot of info out there on threading in a lathe I am sure others will point you at some of it. The 3 jaw that comes with the 7x10 is a reasonably good chuck I doubt your problems are with it.
Regards
Bob

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 the jaws closed. Is that as expected, or do I need to do something to my chuck?
