I saw this video:

The resaw sled looked pretty cool. It was constructed from 3/4" plywood, used heavy duty drawer slides, and a weight to actually pull the material through the blade. Anyone have a link showing how this thing (or something similar) is built? I can see the major points from watching the video, but the little details (like attaching the material to be cut, making the gauge, setup and alignment) would be nice to see.
