I was recently given a Lyman Little Dandy measure but I only have the two rotors that came with it. I approached a local machine shop who gave me a bid of over $50.00 each to turn me out some blank ones, and I do not have access to a lathe. The rotors are an in-between size. No bar stock that size is available. Any help out there? Will RCBS rotors work? Thanks - Goboom
