For the price, absolutely can't be beat, without getting lucky second hand, gear plate was a little rough, it binds up a little in a couple spots, but for the price it's functional and pretty much dead on for true.
I adapted this to fit an antique Southbend lathe. I inherited this from my father. The 4 jaw chuck worked for me for years but it took a lot of time to use . I had to make my own mount for this chuck and it came out great and the chuck is centered really nicely. I would have given it five stars but I had to disassemble the chuck and clean and lube it up to make it open and close smoothly.
