Just finished a set of jaws to fit on my Supernova 2 chuck. I've been trying to figure out how to make a expanding mandrel to hold the rings steady, but just no dice. So I took some pieces of aluminum and started machining on the Bridgeport and this is what I came up with. The hardest part was turning from a 1 inch square down to 0.470 round without a metal lathe. But after burning one full carbide insert, got it done. So far it's working like I expected. I never remember to take pics through the process but I think you all get the idea.
