SCK4-3.75 Wood Lathe Key Chuck, 3-3/4inch Wood Lathe Gear Chuck with 1"x8TPI Thread & 3/4"x16TPI Adapter

The fit and functional design works well. It may be a few thousandths off but for wood turning it works well at this price point. Turned multiple handles/pens so far.The hold and adjustability are good. Solid weight and turns fine so far at speed.

Installed on an old Craftsman 12 inch lathe that I've had for many years. It was a perfect fit. I did have to use the thread adapter. I've used once and worked perfectly. I'll update if there are any issues.changes

From the description I had thought that the chuck body would be cast aluminum, it is steel! Was delivered early and packaged to survive a lunar landing! Great value for a the price. Only complaint is the minimum clamping diameter is larger than would be useable for smaller diameter work pieces.

Works perfectly on my nova comet lathe with a 1"x8 tpi shaft. I was a little worried that it didn't have the worm style key drive to expand or contract, but what do you expect for 60 bucks. It uses 2 little handle tools stuck into holes and pulled in opposite directions, but it stays put. You can see the holes in the pic.

Item arrived quickly, well packaged, as advertised, and sold at a very good price. Jaws are well-made of sturdy cast aluminum with bumper mounting holes precisely machined, and fits my VINWOX SCR4-4 Scroll Chuck perfectly. Jaw set comes with two sets of eight bumpers (short and long) and mounting screws. It happened that one of the long bumpers was missing from the set I received. I corresponded with the seller (SpeedForceUSA); they responded within a couple hours offering an entirely new set of jaws and bumpers since they do not carry the bumpers separately. I accepted their generous offer, and received the new (complete) set of jaws/bumpers in only two days! I now have several spare parts which should last me a very long time. I've used the jaw set a few times and find it to be a very good product from an excellent seller.

Can't beat it for the money, it's a good chuck , good built and works fine for small projects, works great for vases, duck calls small bowls. Love it

I've had this check for 10 months now so I am providing an updated review. Overall, it has worked very well but after a while, my wood work began wobbling pretty bad. I called the lathe manufacture and he recommended some troubleshooting. In short, the culprit was the chuck lost alignment and caused my wood work to wobble. I took the chuck apart, cleaned it, and re-assembled it. It seems to be better now but I will most likely buy a new (better name brand and reputable) chuck to replace this one.

Used it to make my first bowl. Attached it to my VINWOX chuck. You should insure that it will fit your chuck, if it is a different make.Easy to attach, parts are numbered. Now that I have used it, it's a must have lathe accessory, my opinion.
