Perimeter Marble Run RBS

mosignose |

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.
