I've been looking at the capabilities of an indexer for the ShopBot. (Mine is an older PRT96, recently updated control board). I'm not getting any younger (65) and the thought of investing in a new set up is hard to justify. I thought about buying a used unit if someone has one gathering dust, but is in good shape. I was also wondering about building my own? I'm thinking if I bought a stepper motor matching the size I have on the ShopBot now, in theory I could build my own. Is it that simple or is there more to it than that? I'm a fabricator, by hobby, and have a metal lathe, mill, the ShopBot and a few other tools to get the job done. Just wondering if there are stories of other projects like this and what the results were. Sometimes the tool build can be as fun as using the tool once it's built. Thanks.
