I haven’t posted in a while because I got knocked down for a couple of weeks with the nastiest cold I’ve ever had. I’m back in the saddle now, so I got busy building the folding spray booth I’d been pondering for a while.
I considered using wood or metal tubing for the frames but settled on PVC pipe. I’ll use 1-1/2″ for the walls and 3/4″ for the roof.
PVC is challenging to shrink wrap because it doesn’t have the rigidity of wood or metal. When it gets hit with the heat gun, its rigidity becomes about the same as a wet noodle. Shrink too little, and wind will cause the plastic to flap, which can kick up dust…not good for a spray booth. But shrink too much, and the PVC pipes contort. I didn’t do too bad with the roof and wall panels…just a little tight in a spot or two.
It was a bit windy when I set it up, so it took longer than it would on a calm day. Plus, I’m using shrink wrap strapping to hold all of the parts together, and getting all of them in the right spot was a bit of a trial and error process. Still, it only took two hours to set up.
The gabled roof should provide adequate structure to suspend plywood panels with string. That’s the theory, anyway. Time to test it out.
