Nice design for accuracy

Some other companies offer similar pieces which have a notch/flat surface included as part of the design. At first thought the flat is a great idea, and it does have some utility. The problem with the flat spot is the pieces are not perfectly machined from piece to piece. Using two or more to (try to) form a perfectly straight line, which is one of the benefits of the MFT hole system, doesn't work because they are off by a few thousandths each. These pieces appear to be identical CNC pieces so that variation is not an issue.
