DIY Solar Furnace
Day Three – More Painting, Herringbone, Braces
Today I started by making four braces for the ducting. I made these out of corrugated plastic sheet, the type used in sign making.
This will hold the unit together like a radiator. It will also make the whole thing reversible.
Here you can see the ducting in place in the braces.
If you’ve done this right, the whole unit should be rigid and move easily as one piece.
Both radiators are now in place. Nice fit, and the braces will act as baffles slowing the air down.
But like I said - reversible. Flip over and you can experiment with another finish.
..and I chose herringbone.
So one side of the collector will be black, and the other will be herringbone, leaving the galvanized exposed.
You can see in this bigger picture that I used auto detailing tape to detail the herringbone on the collector before painting it.
The finished herringbone looks really sharp. The theory being that the metallic surface on the curvature will reflect light on it’s neighboring collector
So concludes day three.
