Here is a good used lathe chuck adapter plate. It is 10.5" actual diameter. The through hole measures 3" It's hard to accurately measure the od of the threads, the id measures 4.674" so I would guess the od to be about 4.875" or so. It has 6 threads per inch. The recessed part that centers your chuck on this plate is about 9" diameter. If in Michigan add 6% sales tax. Thanks! |
