My solution to the issue of quickly centering the work piece in the chuck was to machine a steel center that would slip into the center hole of the chuck. Then it is just like centering a piece on the tail stock center or the driven center. I am quite happy with the chuck. I knew by its very nature that centering on this chuck would take extra effort.

I have a very simple lathe and did not know I could get an attachment that allowed for a turning chuck, but with the insert every thing seems to work well. I have just completed by first peppermill and found it to be an interesting project. I learned a lot and am about to start on my second. I agree that getting everything centered takes a little time, but thus far have not had any major problems with the chuck per se.

Watch your knuckles! Grips well from the outside if you leave approximately 1/4" skewed "base" on a bowl or similar. Tricky getting all jaws exactly aligned, but it does work. I have nicked my skew chisel twice requiring regrinding as those 4 jaws have a lot of "airspace" around.

I had ordered the 4 Jaw Turning Chuck and didn't know I also needed the TPI insert which I had to reorder. When it came there were no screws included to hold it together.

Are there any special tips to getting it centered? That is the only thing that has given me some problems.

It is definitely the cheapest that I could find, that way I see it, if you are going to sell the inserts and chuck separately, how hard would it be to actually include at least specs on the screws that it does not come with. The screws needed are #8-24 - 1".

What I have found works pretty well to center is first just center as best as possible by eye and tighten just enough to hold the wood. Then I mount the chuck on the lathe and stand behind the head stock looking down the lathe, I pick a spot on the lathe table to use as a reference point and slowly turn the chuck by hand, you can easily see where it is off center and make minor adjustments of the screws until centered. Before I came up with this method the first time I spent an hour centering, now I can do it in a couple minutes.
I also have to agree with Cliff, when it is spinning you don't see the outer edge of the jaws real well and I have hit my knuckles several time also, so I think I'm going to paint the outside of the jaws red. I've only had it 2 weeks, the self centering would be much easier but with a little practice you can center the work in a couple minutes.
