I thought I’d offer up a rotary table and an indexing head for discussion. That is, if they are at all interesting.
I got these from my father about 12 years ago. He had them in his backyard shop in the San Diego area since my childhood. I recall using the index head as a teenager, round about 1976. I was attempting to make my own bicycle wheel hub with a one-piece turned aluminum outer shell and sealed bearings. I had the lathe work finished and was very happy with the result. The next step was to drill the left and right flanges for spoke holes. A 32 spoke wheel would need 16 evenly spaced holes on each side. I set the index head for 16 holes and drill one side. Pulled it off the mill and counted 15 holes!! Scrapped the part because I did not run a test, marking where the holes would have gone. Rookie error. I was so disappointed in myself that I abandoned the project.
The dividing head is from Ellis in Alhambra, CA. It has a 5-inch 3-jaw chuck marked “The Cushman Chuck Co.”
The rotary table is an 8-inch diameter with “Palmgren” in the casting.
Both can use a clean-up but are otherwise in good condition.
