Pietenpol-List: Fiberglass tank weight

Terry B. I had the tank molds at Benton 3 weeks ago. Spent all afternoonmaking the 2 pieces. What a miserable job. I would hate to do that for aliving. I can't say about the weight, but I only used half of the gallonof resin. J. Greenly of Texas(he was at Benton) used a full gallon andhad to buy more. My 4 layers are much thinner and lighter than thefellow that we went to look at his wing. (I went to see his fuel tank)Im convinced fiberglass tanks can be built very light and strong. At thecomposite forum at Oshkosh, They kept quoting Burt Rutan about gettingcarried away with resin. He says most people tend to add at least 30%more extra weight without realising it.

I learned this when I built my canoe (Prospector cedar strip). If you put on way too much resin theglass will even float on it then you have a real mess. Put on a bunch less than you think you need and then squeegee off theexcess that you just put on.
