  • 3 Jaws

    At a recent auction I got a nice 5" Rockwell 3 jaw chuck but it was disassembled. Small problem, the pinion (the part the key goes into) was missing. The chuck key measures .272 square and the hole in the chuck body is .500. Any idea of where I could find a replacement pinion as I have no desire to make one. The Logan Actuator Co. that advertises in HSM could not help. As I recall Logan, Rockwell and Atlas all used this same chuck and just put their logo on them.
    Also there were several sets of extra reverse or outside jaws for the same chuck. They measure .494" and have 5 "threads per inch" or another way is that the tooth spacing is .200". Does anyone need a set of these? John
