I wasn't kidding about that- I worked up a head of steam yesterday and got some tricky fabricating done, the old-fashioned way, by hand. I needed two parts to make the transition between each side of the cylindrical RA housing (on my mystery mount) and the flat support plates. Accuracy has to approach machining tolerances because of the requirement of fitting those gaps perfectly, and that means 'sneaking up' on the correct size, very gradually, by using a cylinder of the same dimension for a form. I'm not there yet, but it is in-process, and that is better than I was doing before (its the shiny part to the side in photo). This topic helped me get it in gear. Bright comets are helpful, too.
