[Csshop] is setting a new bar for building an inexpensive CNC mill. Not only did he complete his build at a very low cost, but it seems to work quite well too. Check out the video after the break to see the device cut out thin wood parts for a toy plane.

The majority of the build uses scrap wood for the body of the mill. The
business end of the device is a flexible rotary attachment for a Dremel
tool which takes a lot of the weight and bulk out of the gantry
assembly. Old flat bed scanners were gutted for the precision ground rod and bearings, as well as the three stepper motors used to drive the axes. An Arduino board controls the device, commanding the stepper motors via EasyDriver boards.

Once the hardware is assembled there’s still a fair amount of work to
do. [Csshop] builds his designs in Google Sketchup, but some conversion is necessary to arrive at code that the Arduino will understand. He’s got a second project write-up that covers the software side of things.

Just when you thought you had to throw away all your spare parts (and even PVC pipes), someone hits you in the head (perhaps God, Budda, whatever), and you realize that you can make an absolutely, simply-amazing DIY CNC machine.
