During the last months I’ve been helping Luke Rickert —of Elisenberg Engineering— to move forward a foundry project. I had a limited experience on foundry business that comes from the rebuilding of a cabinet saw and Luke’s project became a really interesting experience.
All begins when Luke asked me about foundries in Catalonia. He currently lives in southern France and he is really close to catalan speaking lands.
Old mechanical sewing machines are a true gift: robust, nice, effective and useful. Refurbishing them is, however, not so easy. Screws, particulary, are most of them made following old norms or simply following no norms. This is the story of a Singer sewing machine screw.

Because of reasons, I needed to cross drill some shafts with some weird diameters. I own an old imperial Reglus drilling jig but I didn’t have the required bushings. I decided to make some of them. This post shows how drilling bushings where made.
In this post I show the result of carrying a sequence of tests to the rebuild Wörner drilling press to check its accuracy. I took an Aciera 10 drilling machine inspection chart as a reference. Both machines are of similar size and Aciera quality is second to none.
