Our bud Kent Barnes turned us on to this maker’s blog: Sir Richard’s Tool Kit. There are a number of nice projects here, including this sweet little micro mill made from scrap aluminum:

It was a long time in the making, but I have finally finished putting together the micro mill that I started about five years ago. It was one of those projects I started, got 95% complete, then moved on without doing the finishing touches. I made it out of scrap aluminum, some 4-40 and 1/4-20 threaded rod, 1/8″ drill rod, some pieces of Teflon and Delrin, and various screws and bolts. It was all machined on a Bridgeport mill and a lathe. The motor and chuck I salvaged from a 12 volt carving tool. It’s an import with non-standard collets, but it works fine. I made a new housing for it out of aluminum to make it easier to mount on the mill.
