Made with the help of machinist friend.  The plate is cabinet grade aluminum, and the holes were precision drilled in a mill with a rotary table.  Will work in any lathe with a 1" spindle, the distance between the holes in the arm will be 1/2 swing - 1/2",  in this case 4-1/2".  The indexing pin is tapered for a snug fit in the holes.  The arm support is oak!  It can be used with a nut, which allows use of the Morse taper, or with a chuck. 24 holes allow division into 4, 6, 8, 12, and 24 segments.
I will have a few plates for sale soon. I will post in the classifieds.
