Thanks for the suggestions. That's one of the idea's I was considering. The side holes are REAL small so using them for mounting isn't really an option (#60 drill I think...around .04" diameter). But that top piece may be enough to clamp on to (around 1/8 of flat space before the bearing bevel).
I was thinking of cutting a block of alum to hold 4 of these side by side. Each for one of the position changes. Then I could run a program that cuts all 4 in one process...then I would move everything one step down on the assembly and start the run over again.
I also read idea's about leaving a couple tabs a few thousands of an inch thick and then just cutting it off with an exacto blade. It's manual labor, but the clean up should be minimal.
