[Howard Matthews] never throws anything away, and because of it he was able to build this CNC mill using parts that he already had on hand. He pulled stepper motors out of broken stage light, precision rod and bearings from old dot matrix printers, and other various bits from his junk bin. We’ve seen [Howie's] handi-work before, and this project is just as fun as his Land Rover’s replacement speedometer. Some highlights include manufacturing the nuts for the precision rod, and building a rail system for the bed of the machine. The latter looks a bit suspect, as any milling debris on the rails will cause you Z-axis problems, but now that he has bootstrapped a working mill perhaps he’ll machine an upgrade.
Update: Fixed the link, added video after the break.
