Now laser cutting might work...

Generally some sort of material is put inside the extrusion so that it only cuts through one wall; 233 has done this, and I believe they use a 4x4 piece of wood inside of 4x4 extrusion when they waterjet that. I'm not sure if it would work with wood when applied to a piece with only 1" thickness, but I'm sure there is something that would.

I doubt that most have done the math. And a cantilevered wheel on a 1" x 2" aluminum frame member that has been skeletonized makes me leery of the durability. Obviously it depends on the amount of stick-out, but I was surprised at the twisting forces we encountered when using full 2" x 4" x 1/8" box aluminum. Your results may vary.
