school bus deck, etc, etc.

Still needs powdercoat, but pretty much done with the fabrication. This is a 7' x 7' deck for the top of the same school bus that got the solar panel rack. It's been fun to work on something that has some free-form lines to it. Gave me a chance to experiment with my tube roller.
I'll put up pictures of the finished deck when it's installed.

There are removable 6' posts that sleeve into receivers on the deck to make a safety railing and for hanging rope lights. When stowed, they fit under the eaves of the deck and are captivated in place by a clevis pin, mocked up in the photo with a piece of 1/2" tubing.

Other ostensibly interesting projects are a modular bike trailer for my friend Austin, who wants a set of trailer hardware that can be bolted onto an aluminum extrusion frame. Taking a leaf out of the automotive design book, we opted to use spherical rod-end bearings to allow for different configurations of the tongue.

I also finished up a quick bike trailer project for a local naturalist and ecological restorian to haul native plants and horticultural implements into the bush:

The organ trailer is nearing completion. The only major design element left to finish is a canopy to protect the rider and instrument from the sun and unexpected rain showers. I'm currently reaching out to textile experts for consultation on tensioned fabric structures. If anyone out there in cyber land has experience or inclination toward designing tensioned-fabric things, please let me know.
Anyway, here's what I have so far, just about ready for powder coat:
