Have you checked out Penn State Industries? Lathe Chucks at Penn State Industries I have 2 chucks from them and a Oneway , one from Grizzly, and another small off brand . OneWay is the best and most expensive. The "Barracuda" chucks from PSI have served me well------they come with several sets of jaws, a screw center, tommy bars, and chuck key. Sometimes a special will include jumbo jaws. I probably use them as much as the OneWay.Looking for "decent", not best ever invented, chuck for my HF lathe. It looks to be a 1", 8 TPI. Any advice would be helpful as I have never dealt with one before.
I assume jaws are not interchangeable between makes.
