drez20001 built this CNC machine using plywood for most of the structure, all of the slides have been made using drawer slides. I have seen this done quite a few times, some of them are very tight and smooth. The only concern I would have is longevity but they are cheap and for a hobby machine it sure makes the price right. He is using a small rotary tool for cutting which should be sufficient for most small projects. Only issue with the small tools is they might heat up and self destruct if it is being used continuously for many hours.Â
