In the beginning, I was cutting an 8 foot bar of 1.5 dia Delrin on the bandsaw in to 1.062 pieces! That was so much extra work, and a loss of much materal! So I bought a 90 deg head and a stub arbor for my Milling machine, along with a 1/6" x 6" dia saw.
Now my shop looks like a blizzard in Florida! The saw cut the parts really nice, the finish was excellent because I stoned a slight radius on all the saw teeth! The length held within .005 (due to chips on the stop), and a nice parallel cut!
Now I have eliminated a second opperation of facing the parts in the lathe, so next opperation is to set up the 3-jaw chuch on the mill to drill, Countersink, and 1/2-10 Acme tap all the Delrin blocks!
The next opperation is to screw them on a piece of Acme thread in the spindle of the lathe, and turn the flange and face slightly to true it to the thread.
Then my last opperation is to drill the 4 holes in the flange, then sell them on eBay!
If I only has a CNC MILL or LATHE in my garage!
