#984 Denzil Hughes asks about Amana tool CO-136 Router Colet Assembly 1/2 Inch Shank for Porter Cable 690 and 890 Series Routers, Comparable to Porter Cable 42950 Oct 18, 2022

What are the dimensions of this collet at the base and of the nut. Also what type of threads are on the nut. I need a 1" nut and 12 threads per inch to fit my router (an old craftsman shaper/router). Thanks!
