Sometime ago someone posted a technique for making replacement engine cowlings out of plastic bottles. He said he made a rubber? mold of the cowling then made a plaster casting of the mold. Using the plaster casting and a heat gun, he shrank a plastic bottle around the mold creating an exact replica of the original cowling in plastic instead of foam. He said this process created a much stronger cowl.
Since HK won't provide replacement parts for the Big Durafly Cessna foamie, I'd like to try this process for making replacement parts...especially the cowl before I actually fly it (and crash it).
I've done many forum searches for postings over the last six months and the last year and can't come up with the original post. There were not many details in the original post and I'd like to have some more specific info about how this is done.
Does anyone remember the original post or know anything about this process.
