MakerFX was given a Prazi SD300 Mini Lathe by the fine people of the FamiLAB machine shop.Its a good mini lathe, made in East Germany (when it existed), it just needs some love and parts to become fully operational again. A lathe is used for turning material about its central axis and removing material with some form of hardened steel or carbide cutting tool. Its use can be for custom brackets, bearings, knobs, fittings, etc.
