The bases are fairly small parts, so I’ve attempted to work in as many pieces as I can at one time. The CAD file 065 Base Setup (AutoCAD 2010) includes my layout as well as some other layers with sketches of the milling and turning fixtures I made as well.
I had some 10mm diameter 416 Stainless heat treated to HRC35 left over from a previous job. Even though most of the time was spent converting it from round to square, overall it was not very hard. However, don’t underestimate the added complexity such small parts can add to fixturing.
