We recently received a letter about and pictures of a vintage threading machine from a New York reader who asked if we knew anything about. We don’t – nor do any of my go-to sources. But I’ll bet some of you can help. If so, please leave responses below, and I’ll print them and mail them to the reader (or perhaps he’ll see them here). And if not, well, the pictures are just interesting to ponder (click on the images below to make them larger).
Please find enclosed some pictures of an old spindle threading machine evidently made by a very adept craftsman. As you can see, there are many wooden threaded thumbscrews that allow for infinite adjustment with all components of the machine. Cutters are located at the entrance and exit of the “cutter box.” The main frame slides in and out on heavy rails and there is a separate frame that must have held some kind of additional cutters or cleaners.
I thought it might be for making bench vice screws, but it looks like it has only about a 10″ throw.
