Z011 4-Jaw Lathe Chuck with Connecting Rod and Wrench, Self Centering Wood Turning Chuck, Power Lathe Accessory

Necessary tool to begin turning square wood blanks on mini lathe.

Not only is the description misleading that it is not a self centering chuck, the tolerances are some of the worst I have encountered. Buyer Beware this is not a good or even slightly recommended offering

so I got this to make relief cuts in 2 stroke pistons. As I got it out of the box I first realized it does not self center. so Im already mad about that. I put the piston in it, centered manually as best I could, and tried it. The piston flew out of it immediately with nearly no side pressure. Absolutely worthless. I started a return immediately. Then after thinking about having no other real way to make these cuts I decided to try flipping the jaws around. I flipped them to the stepped side like pictured in the ad. Went out and tried it and it worked flawlessly. I used a calipers depth gauge to center it as much as possible.

If this is something you are looking to use regularly, get a better tool. (even though a higher cost may not guarantee better results) The jaw slide channels had binding burs on them that I had to file off, but I did finally get them to slide properly. The worst thing about it was the adjustment screws and thread cuts. They do not line up very well and were filled with shavings. I've included a picture that shows the shavings after the second time disassembling it, cleaning it, and reassembling it. They operate somewhat better now, but I'm going to have to do it again. They are not smooth at all. This will probably work for the one or two things I needed it for, which is why I went for the cheap one, but if this is a tool you expect a great deal of quality from, get something else.

You have to realize, this is a very small non precision piece. You aren't buying a $200 Chuck for $35. Manage your expectations...Remember it's not an expensive 4 jaw Chuck. But for me, it worked fine in a drill to hold some oddly sized small pieces. It's definitely not self centering..

jaws are VERY sloppy and made of aluminum or pot metal the adjusting screws for the jaws are almost falling out. This chuck wouldn't last a week under use, if you could even get it aligned.

I must not have read close enough I bought this to put on my lathe but when it showed up it was so comically small you could use it in a drill or a drill press I don't know why you would ever want to put a Chuck in a chuck. Besides being totally useless for what I purchased it for it seems to be fairly well built

This is meant to attach to an electric drill chuck, which it does it can hold for example, an aluminum tube an inch in diameter. If the tube is less than an inch long, one can use a lathe tool to machine the end of the tube if the tube is much longer than an inch, there is too much wobble to actually machine the bottom of the tube. The tube would need a centering device from below.

Funciona bien, aunque está muy pequeño.
