Well I am back to the 1/8" plate! I belive I can thread it and still have enough to put screws in it without it pulling out. I have a couple 2"x2"x1/8" AL plates cut and I am about to hook up the CNC mill to make the design in the base. I will probably end up making the O ring groove in the acrylic middle section or maybe not use an O ring at all and just use the silicone I usually use. Anyway later tonight I should have the cam working again and I will post some pics of what all my rambling is about.
