Has anyone done a JGRO or Joe build using extruded aluminum for the frame, bed, and gantry?

I’ve been a woodworker for quite some time, but have no metal working equipment.

However, looking at the extruded aluminum at this site, http://www.tslots.com, I should think you’d be able to bolt together a frame and gantry without any real metal working equipment. I have used my woodworking equipment to cut aluminum to size so I expect this should be possible.

I was just wondering if there was anyone out there that’s given this a try.
