Converting the template into an actual dimensoned pattern......
I'd like to build a trailer shell following the template, but with flat panels that are precut to shape, zeppelin-style. Undecided on a riveted aluminum skin vs foam panels to then glass over, or soaking an inflated envelope with resin, then building it up, but am leaning towards aluminum (possibly with a spray-foam interior layer to stiffen and insulate).
So far I've struck out on finding a pattern to scale up. Closest thing is these hot air balloon panels from a crafter's blog (don't laugh if you click through).
