Don't laugh -- it's only a humble nut! Needed a particular size to suit an old UK thread (3/8" x 20 TPI BSF). The process, for something so simple, is a bit tedious due to the several stages. The 'quick fix' is to find a nut close enough in size, and drill it out and tap it! Here we did the slow way, working from solid with a piece of 3/4" hex, which happened to be pretty hard material. |
