Don, could you give me a pointer or two on removing the 3jaw chuck? I know it screws on & it apears that I have some holes in the sleve behind the chuck but I cant get it to move. Thanks, Ron

Ron.
Remove the 2 clamps, use either a rod (the chuck wrench handle fits) or a hook spanner to hold the spindle, then use a bar in the chuck jaws to unscrew the chuck.

Hey, the pic looks just like the one I got. Have you figured anything out with the threads? I cut 1 in 16" threads last night using the 1in 18" threads setting & they worked! just a little bind at the end but not enough to hurt the threads! Thanks, Ron

We are working on the threading right now, I think we are going to have the manufacturer look into it, I am thinking the chart is off.

I had the same problem on a new 10x22 lathe. I chucked a large nut in the 3 jaw,put the handle of the chuck key in the spindle plate and pulled on the nut with an 18" crescent wrench.Bent the handle of the chuck key.
I then heated the chuck near the threads with a heat gun for about 2 or 3 minutes and the chuck spun free. I expected heavy grease that was on the ways to be on the threads. Nice and clean though,I imagine who ever installed the chuck ran it up hard.
I turn the chuck up to the spindle plate and back it off a quarter turn,then install the clamps.
