AogbraAogbra 3.75-Inch 4-Jaw Wood Turning Lathe Nickel Plated Chuck and Laser Etched Jaw Set with T Bar Wrench and 6 Point Star Fasteners (1 Inch x 8TPI Thread)

I have been using this set for two months now and am very satisfied with it's peformance. I am just fooling around with wood turning and for the smallish stuff that I make it really seems to do the job. The largest bowl I have turned with this chuck netted out at 9.5" dia. 5.5" high, out of a much bigger piece of wet oak from a tree that came down this winter. The pic I provided is a much smaller bowl 6.5" x 3" from almond wood. The largest bowl I turned with a mortise and this almond bowl is the first I turned with a tenon. I used a two step tenon and easily faced off the unwanted material with the large plate attachments using the rubber jaws. It worked perfectly! If you want to turn massive stuff you might want to step up to something more professional but for hobby work this really expands the range of things I can make out of what would otherwise be firewood.Edit: I found that when using the parts identified as "Cole Jaws", you will find that the socket head screw heads, which sit above the rubber bumpers, can be pushed into your work leaving marks. I found this especially problematic when chucking on the inside of a bowl. I solved this problem buy purchasing a couple feet of clear vinyl tubing, 1/2" O.D 3/8" I.D., available at pretty much any hardware store. It is a tight fit over the rubber part but that is a good thing. I trimmed the tubing off flush with the top of the screw head and then proceeded to repair the damage done by the unprotected screws the first time through. It works great!

I got this chuck 4 months ago because my previous chuck was getting worn (one with the tightening "bars" and the holes the bars go into were getting deformed from tightening the chuck). I got this chuck specifically because of the tightening mechanism, hoping it would be less likely to strip.Immediately upon first use I realized it was not centering very well. The attached video shows the run out. It varies but is always at least 1/16" and is often over 1/8". That is pretty off-center for a self-centering lathe chuck. For the type of turning I do, I prefer something with a runout of 5 thousandths or less. However, every chuck I've owned has had some sort of run out and I've learned to not remove the piece I'm working on until I've finished turning, so I lived with it.Within 2 months of use I noticed the tightening tool was bending. I'm not He-Man; I'm 6'2", 165 lbs. I'm not sure what kind of steel this is made from but it's not hard enough to stand up to a lot of use. Sometimes you can kind of turn it and bend it back the next time you tighten the chuck, but it shouldn't be happening and is very annoying.The worst part is recently the chuck has been "sticking" when tightening or loosening it, especially when loosening. It totally locked up on me the other day and I had to smack the jaws repeatedly to get it to finally let loose. It was still very sticky, though. I pulled off the jaws and looked at the underside where it contacts the gear in the chuck housing, and there are grooves in the jaws from the gear in the housing. The gear seems to be mostly unaffected, so it would seem as though the grooves in the jaws are of a softer steel than the gear. There really isn't any fix, since you can't tap it like you might a bolt. The grooves are too big for that. So at this point it's just a short amount of time before the grooves in the jaws get bad enough that it will need new jaws or just get trashed.Really not happy with this one; $180 is too much to pay for a chuck that lasts 4 months.

First thing, I was impressed with the case it came in and the quality of the machining. I have used this chuck for several months, in many different configurations. Changing out the jaws is very simple. Ive had none of the problems some others have had (wrench bending or out of round, or run out). I would buy it again without hesitation.

Only thing I don’t like about it is lack of instructions. Easy enough to figure out but hard to tell how much torque you can put on it when tightening stock to the chuck. Very nice set and a decent case.

the case was flimsy and arrived damaged, there was a big hole in the case because the parts are heavy.I contacted amazon customer service but they said they couldn't ship me a new case and I would have to return the entire item. I decided to just keep it in a broken case rather than the hassles of retuning it.
