Just an update where I am at. My kit arrived safe and sound from Pete today.
I have the design pretty well finished up. I did not need a CAD program as outlined below. A shop with a CNC mill just wanted the X and Y coordinates for each hole, what size were the plates and where was "0" located. They will use those coordinates to cut out the basic holes for me to finish tapping and countersinking. I will use a 1/4"-1-3/8" Unibit to get the two step look. for the 23 front and rear holes in the 3/8" plates. I am doing this all on paper but I have it just about done and will bring it to them to get the holes drilled. I just did not have the skill Michael has to be right on the mark for each hole so this should get me close. I also was able to calculate the two radius needed for the curve on the bottom of the plates with the tangent points where they meet. When I get done with the plates the shop will stack all four of them together and cut out the curve and the angle on each end in one shot. The rest will be up to me to finish. It was funny that I did it in metric and they wanted everything in decimals. I had to convert everything over. The shop was very reasonable in the price as they will load my calculations into the CNC mill saving a lot of time for them. The shop also could of done all the other machining but that would drive the price up quite a bit so this was the best bank for the buck so to speak. The full size drawings I drafted looks like everything fits well and should come together without too many problems. I also got all the switches, Jacks and LED's and fitted them in a scrap piece of aluminum to see what panel thickness, clearance hole size and depth would needed to be milled out from the back side of the plate for them to fit. The shop would be able to do both operations per hole at one time if they drilled all the pilot holes from the backside of the plate. I was able to get that included when they drill all the holes for each of the 4 plates.
