I forgot to add the photo of the part with the hole pattern in it. With the mating piece on the bike side by side you see the part start to make sense.

If I were trying to do this on the old Bridgeport, I would have sprung for the hex collet block and indexed for the hex and the holes all at once. I do have a rotary table, but just the standard faceplate and no chuck. If I'd tried doing the hole pattern with coordinates, I'd likely be out of position. This CNC, even though only two axis, is making life so much easier.
