I have four of the Barracuda chucks... one with a number 4 jaws, one with pin jaws, and one I swap back and forth with the number 2 jaws or a longer set same size as number 2, plus one dedicated to my cole jaws... all work for what I need them to do, don't have any problems with them, except if I open the Cole jaws too wide, over the 8 inch size, one or more of the slides will drop out of the jaws... it's my oldest chuck so may be worn a bit... also have a Grizzly Barracuda look=alike that has number 2 jaws that open slightly smaller than the real Barracudas.... also tends to slip occasionally... and jaws are not interchangeable as I had hoped..... my primary complaint and it's not a real issue, but it takes three hands to mount a bowl blank if the jaws are on the spindle... I usually mount with the blank on the ways and let the weight of the chuck set the jaws.... the tommy bars get to be a pain sometimes... would rather have the single key like the Nova or other name brand chucks. Not going to change at this stage as too much $$ tied up in the chucks I have.
