Tell us about yourself!
I know the article says "acrylic" but in fact I used polycarbonate, which I strongly recommend. The windshield is still on the bike, fittings still look good; no issues. I don't understand why josuchav is talking about galvanized metal here. I used aluminum cookie sheets in the oven, but even if you were to use galvanized sheet metal the temperatures involved will NOT cause zinc to vaporize and "kill everyone in there". Pig iron is cast iron blocks (won't work) but carbon steel should be Ok, as long as it is polished shiny.
