Okay, here is the question. Profile or serrated edges?

Why?

Hmmm, not a lot to choose from.

There’s Chuck Norris – definite NO
Chuck Yeager – he does cut a nice jib in his uniform
Chuck Berry – too flakey

I think I’ll abstain.

I don’t think you really have to choose between serrated edges and a dovetail profile. They’re different jaws for different things. I think the serrated edges are for holding super strong onto a piece of wood that you know you’re going to turn off or part off. The profile edges are intended to hold surfaces that you want to keep.

I finally got a set of dovetail jaws for my Barracuda2 and PSI economy chucks. I used it in a recess that I wanted to keep, and it held really well. When you think about them though, there’s not really ever going to be enough material on the slope of the jaws to hold as well as a dovetail joint. They hold well, but if you put enough of the wrong kind of leverage on the piece, I think it’ll definitely come off.

I feel more secure with the serrated jaws, but have popped pieces out of them too. I got some serrated alligator jaws from PSI recently. Haven’t had a chance to try them out yet them. They have a lot more holding surface, so I’m hoping they’ll hold better. If nothing else, being further from the chuck body will be nice.

I’m trying to experiment more with different methods of holding wood. I’ve got a Beall spindle tap and have been trying to make some jam/friction chucks with it. I don’t know if I’ll ever try a vacuum chuck, but that’s an interesting concept at the least. I’m going to make a Longworth chuck soon and one of those bowl sandwich chucks, I forget if they have a name.

Have your say...
