Question: What is the center to center distance of the two mounting holes on the chuck jaws.
Document: These jaws seem to work with PSI chucks only. I tried to fit them to two chucks that I have and they did not work. Unless you have a PSI chuck, do not order this item.
I have been turning bowls with a screw chuck for about 2 years. I recently bought the PSI Barracuda Chuck and the Jumbo Flat jaws. What a difference!!! These jaws make finishing the bottom of a bowl or project SO MUCH easier. No more re-centering and no more screw holes in the bottom of your work piece! If you enjoy wood turning, you need this set of jaws with a Barracuda Chuck.
Works great, don't know how I managed without it. A second chuck to  mount it on and leave it on is a good idea. Comes with two sets of rubberized pins, short and longer, and have used them all. Solid construction and fit without any problems.
Fits perfectly on my Barracuda chuck. The post holes have been machined so well I seldom use the included allen wrenchI have used it finish the bottoms of bowls and vessels. Also performed well to turn a oversized spatula.
It's a nice addition to the Barracuda chuck. It comes with two different height "pins" that you can screw in. My only complaint is that the rubber/plastic covering the pins is a bit hard and not very sticky. I was expecting something a bit softer with more grab. I've only used it a couple of times to try to fix up some out of round bowls and each time, I've had a catch and the bowl goes flying out... Guess I need to work on my technique.
Very robust set of jaws with extra tabs as well. Highly recommend this as a add on to the Barracuda chuck.
I have recently used these jaws to reverse chuck a bowl so I could finish the bottom.of the bowl. They work perfectly without damaging the finished surface of the top of the bowl. I am very pleased with these jaws.
Got this set of jaws for my Barracuda chuck. As a new turner, I'm still looking for ways to simplify and improve my work. I turn bowls and hollow forms and I'd say that these are essential at this point for me. Well made overall.
I started finishing the bottom of a bowl using the long pins to hold it  , I changed to the short pins, then I loosened my chuck and moved the bowl 1/4&#34; away from the flat jaws and retightened , the bowl was always held firmly , I'm happy  with it !
Bought this set of jaws to use with my Baracuda II chuck for turning the bottoms of bowls. So far it works fine. I also apply a few pieces of masking tape for a little extra safety in holding the bowl. I can't see how a more expensive set of jaws would do the job any better.
Answer: yes
