Router lathe build

router lathe with internal thread carriage attached

Here's a chronological listing of posts on building the router lathe. I started in May on 2012 and wrapped up the initial build to a point where I was making parts in early June. It's still pretty rough: there's still much to do, but it works.

The end result, so far, is a wood lathe with 5.5" swing over the bed and 33" between centers, with a router mounted on a carriage that travels parallel to the axis of the spindle. Stepper motors control and synchronize the travel of the router carriage and the rotation of the spindle. The depth of cut (moving the router in and out) is still controlled manually. For internal cuts, the router is rotated 90 degrees and uses a belt to run a cutter on an offset spindle. The whole device is controlled by an Arduino Uno.
