I am an amateur, home shop machinist. I bought this chuck with the back plate and shipping included for less than $125.00, an outstanding value IMHO. The two-piece jaw configuration was a requirement and the source of some problems that may or may not affect your decision to purchase this chuck. If you purchase this chuck, be prepared to disassemble it and thoroughly clean and lubricate it. This one was FILTHY, but I expected it would be. After cleaning, a precision 0.5000 pin ran within 0.0020" TIR. , well within spec. I trued the back plate mounted on my lathe spindle (70-year-old South Bend 9-A) and turned the register boss to 0.0050" smaller than the register recess in the chuck body. The test pin repeats within 0.00050 after assembly and adjustment. Amazing IMHO! I removed the top jaws and cleaned the interfaces with the jaw base. Upon reassembly, I could not get the chuck adjusted any better than 0.015" TIR. I reground the key slot so the top jaws would actually seat properly. I will regrind the jaw faces under clamping load with a tool post grinder when I get time. In the meantime, I'm using machinable steel top jaws to hold some 2" diameter steel discs for turning, facing and boring on both faces. The chuck repeats within 0.00050" TIR with this configuration. Again, amazing. I would purchase this item again but only if I had time to do the aforementioned rework.

Very good tool, runout was only .002 thousandth installed out of box. Very good for what I use it for. Neighbor bought a 4 inch to expand centrifugal clutches , I had to machine jaws thinner for unique tool use. The 4 inch was so nice it caught my attention so I ordered a 6 inch to put on one of my small lathes.
