Our always-on-the-leading-edge friend Phillip Torrone over at Make just posted this sweet Dremel-powered mill a bit ago. It provides a firm, adjustable mount for your standard Dremel rotary tool, enabling you to take on milling, cutoff (pictured), thickness sanding, and sawing operations with surprising accuracy and ease.
Vanda-Lay — the manufacturer — claims it can produce work accurate to within .001″, but honestly I imagine this as more of an “interim” tool than a mini-mill replacement. Rather than questioning its ability to mill to a thousandth, I’d rather look at it as a lot more accurate than what I can do with the Dremel by hand — or with any of Dremel’s mounting tools or attachments. For example, we’ve used our Dremel in combination with a vice and other mounting tools to “machine” plastic parts on the fly. This would just make it a lot easier.
(Thanks John, for the tip!)
