Big canopy is up

factoid

We got it all rigged. It took the four of us about half an hour to get it all monkeyed together, website like this but by god, it stands – at least it still is as I write this, two nights later in peak winds of 18 mph – and the whole thing hangs together structurally as if it could stand more. How much more remains to be seen.

I think I’ll need bigger rope, in the long run – no telling how much damage the rope will take from the ringbolts it’s passing through. I wonder if I should run it through pulleys there, like tall ships do.

It just needs to be realigned around the shoulders, and it’s missing a couple of gussets at the ends, and perhaps a sewn-in draw-bar for the canopy end.

That wicked line buzz is gone. It turns out I needed to ground the mixer to the chassis, link which involved tearing apart and then sewing up the 20-foot umbilical. That took a little while.

Pay no attention to my banging. I’m just banging. But it’s sounding pretty lush. And I”m excited to show it off. Thanks to everyone who pulled up and talked to us this afternoon. It’s all good.

Just a little more wiring to go.

Fold a nine-inch wide strip of fabric (at 60″) into a strip four layers thick, seam its long edges, and then cut it into strips about six inches long.

Then seam the cut edges and voila – a little stack of stout reinforcements …

… to be sewn into place to keep the fabric all in one piece while still letting the air flow through.

Roof shade – the sewing begins in earnest

factoid

Step one, ailment attempt to throw together an enormous framework of PVC pipe to arc over the van like some demented logo for caffeinated high-fructose corn syrup ‘n’ gutbombs.

Valiantly attempt to model it.

Then, when that fails, toss the PVC aside and acquire some 1″ steel conduit and connectors for a new frame, which you injure yourself building.

Then start sewing. (more photos after the jump. Continue reading
