Made a Nudger

Tony,your explanation helped. Back in the 70's,even my NOS 6" Union chucks ran .003"out,and I considered that as good as it was going to be. I couldn't afford adjust-tru chucks and the like. So,this could push semi-loose jaws a little. Good idea.

These days,my Bison chucks run VERY true,and I actually use collets most of the time on the HLVH. On my 16" lathe,I snared a Cushman collet chuck that takes #215 collets,which are MUCH larger than 5C's-and apparently as rare as hen's teeth. I have,except for 1 or 2,the whole set. I'd have to look,but I think they go up to about 1 1/2",maybe larger.
 
Well, George, I didn't want people to think that this tool was a panacea for all chucking issues. It may be good for some things, but it has limits.

Somehow, on the Acer lathe that I bought new in 97 (I think) the 10 Strong branded chuck it came with has been remarkable. I can toss virtually anything in and with a little twist as I snug up on the primary pinion, I'm disappointed (rarely) that I have more than a couple of thousandths runout. And it's been used a lot. If I carefully tap on the part with a deadblow, I can easily get it to a few tenths. But even if not particularly careful, it's plenty close for most everything I do. It's surprising. I figured they would put a cheap chuck on it, and having never worked a Strong chuck before, I was prepared for a while to replace it with a buck style chuck. Never happened. It's been an outstanding chuck. But then, I'm careful with it, and haven't wrecked it.
 
This is not a fix all for setting up in a chuck, just a quick way that I copied, and it works for my HF lathe. I dont have any new steel that I work with, mine so far is old stuff torched off of a car or another project so it is usually pretty rusty or painted :angry: So far it has helped me in setting my junk up quicker :)) Your mileage May Vary
