Not in the metal, but the wooden trial-fit items. I had some laminate flooring lying around the workshop, so this was pressed into service. The "dovetail" sections are actually squared-sided for simplicity of production and also lack a gib strip, of course. It allowed me to discover a major flaw in my initial measurements such that the centreline of the pattern follower stylus was 30mm higher than the corresponding holes in the supports. The photo shows the components after applying the required correction. There is still some interference between the chuck and the left hand support, but that is exactly the sort of interaction this was intended to highlight and is just a matter of tweaking the shape of the support.
