Adam you said you got some arms. Who was your source? I have some arms that I believe are investment casting in 17-4 stainless steel. There seems to be some voids in the inside of the arms where they need to be bent. These arms have been on the market for a long time . Can they be bent safely? I dont know! Any engineers know the way to bend these arms safely? Can they be bent safely? If not can someone make a suggestion for material to machine them from solid and then bent without the need for heatreating afterwards.
