Default Nova pen jaws...big disappointment

I guess I'll have to call technatool support and see what can be done.
The same problem I had with the pin jaws.
They sit straight when on the table and they come together straight with nothing clamped. But, when there is anything clamped in them it only holds at the back and the part can be wiggled around.
I even spent the better part of an hour taking the chuck apart and cleaning everything.
Since the same problem shows up on either jaws then I'm going to guess there is something wrong with the chuck.

These jaws (Pen Jaws) have a history of this exact problem. The tecs at Teknatool are helpful to resolve the issue, which is to replace defective jaws. Since you have same issue with other jaws, it could be the chuck. Call 'em.

I installed a set of the pen plus jaws tonight expecting problems. At first alignment looked a little off but I was able to back them off, loosen the screws, realign and retighten. Everything lined up well and they worked great. Happy I ended up with a good set. The machining was rather coarse compared to other Nova parts and pieces, though.

I've pretty much given up on Nova products.

16-24 lathe - Straight out of the box it was unusable. Runout isn't a strong enough word for what it did. You could chuck up a pencil and draw good sized circles/ovals with it.

16-24 lathe tailstock - Base is machined too short, luckily pieces of a pop can used as shims under it bring it up level.

SuperNova 2 chuck - Not bad, no problems yet.

Pen jaws - Same problem as most everyone else

Cole jaws - One is slightly different from the others, the other 3 sit flush and even, but one sticks out just enough to cause problems.

Customer service - Abysmal

Well, I know we are supposed to 'read the manual first'. Right...I almost never do.
Hehe, when I looked at the front of the manual, it says 'Beta test March 2013'
Gee thanks amazon. You are selling old stock and beta test product as well.

When you say pen jaws, are you referring to the Pen Plus jaws? The jaws are 1 1/2 inch long or are you referring to the shorter ones that Nova calls pen jaws?

I have been using the pen plus jaws almost since I started turning, and I have used the same pair of pen plus jaws on two different G3 chucks with out any issues. I bought a fairly pricey brilling jig for drilling on the drill press and had terrible results with it. That was when I went to the G3 chuck with the Pen Plus jaws.

No problems with these.

No problems with any of my Nova chucks or jaws. The Tech support people are always very helpful whenever I call. They seem to want to solve any problem you may have any way they can. Call them.

Thanks all.
I filled out an Teknatool online form and got an email today.
They are going to take care of this.
A fine company to work with.

I guess it's the luck of the draw. I have a Nova chuck, 2 sets of cole jaws, the pen jaws, and 3 other sets of jaws. I've never had a problem with any of them.
