I just acquired this chuck....

This chuck is best considered a smaller update of the original Nova, and actually has very little in common with the Compac chuck they eventually withdrew from production (and I must say I've had a Compac for many years and it has always worked well for me).
Given my limited hands on experience, I can say little definitive, but overall the chuck appears to be the only quality chuck in the under $200 range, and offers a lot of performance for its very modest price.
The up side of the chuck is that:
- it will take almost all of the very large family of Teknatool jaw sets
- it is small in size, allowing a lot of clearance on the headstock end when working with small scale turnings.
- the body itself is threaded, keeping the cost and size down, the latter giving you about an extra inch of between centers length compared to my Talon.
The down side of the chuck is:
- the body itself is threaded, which limits its ability to be mounted to other larger lathes (of course in such cases one is likely to keep their mini-lathe and keep the chuck dedicated for use with it).
- it uses the Tommy bar style of adjustment, which is not as convenient as a key style and won't generate as much force as that style of chuck (of course, for smaller work, one can more easily support the work while actuating the bars, and most smaller turnings aren't going to need or benefit from super clamping force).
There will be more to add to these lists, such as smoothness of operation, reliability, etc. that will only be revealed over some extended use. Still, right now, it offers the small size I prefer with a mini-lathe and the price is so modest that it will be hard for it not to rate highly on a cost/performance basis.
If you have more money, and don't mind giving up a little between centers space, the Talon, the Vicmark and the SuperNova 2 are all excellent chucks, but if price is an issue, I think the Precision Midi is likely to prove a very credible alternative.
More later when I can get back to turning
