I don't have a video that shows how it works at this time. Perhaps I should make a video. The Unimat DB200 in skilled hands equipped with the proper tooling is capable of building this Small Quick Change Tool Post. I would suggest making it from aluminum and hard anodizing it for long term use. It can also be made from steel but will be slower machining. Of course, if you have larger equipment available it will go much faster. Good work can definitely be done on the Unimat though.
