Here is a perimeter marble run around my sons room. The track runs around the entire room near the ceiling. The supports are walnut and a majority of the tracks and other parts are birch. Gear motors are run by "AA" battery packs. The marbles are 1 inch diameter.

This is just a slide show of the pictures from my written instructions in INSTRUCTABLES.COM. This homemade M72A2 LAW laucher will launch a Nerf Pocket Vortex (discontinued product) about 100 yards.
