Your attempt will surely fail unless you see a real plate!
Something inherent to the design of a trapezoidal-shaped plate like the RRS plates is that if you keep tightening it, it will eventually clamp with screw-type clamps. All I have to make sure of is that I am within the tolerances of the clamp. I cannot have the plate's base wider than the clamp can open and I cannot have the plate's base smaller than the clamp can close onto. For most instances, this is not something that requires a tolerance of 0.001", let alone 0.125"! Most screw-type clamps can accomodate plates that are a little smaller or larger than the ones designed for it. Even if the groove is not deep enough, the clamp will still hold onto the plate....but I'll probably make it "deeper" than visibly necessary.
I think I found an answer on RRS's website. Their multipurpose rails are 1.5" wide and 0.37" high..the exact dimensions I have in my original drawing, actually, haha. I'll put a light chamfer on the edge to ensure it doesn't have sharp corners like my drawing. My drawing is like that for simplicity's sake. No way would I expect any of you, let alone myself, to have the tooling to determine the radius of the chamfers.
Also, my workplace prohibits me from doing work-related projects for personal benefit (i.e. selling the stuff we make without approval). This is first an foremost a project for learning CNC. It is secondly something I am interested in and can take home and use, instead of practicing on scrap metal making worthless garbage that I don't care about making look nice. I am getting paid to make it though, which is definitely a bonus.
