I have a need for some lengths of styrene sheet with a linear curve to them.I want to replicate in 1/25 th sale is about 20' of sheet metal that transitions from flat on top to flat on the side like a travel trailer roof to a flat side sheet.I am considering heating sheet styrene sheet with a heat gun then wraping it around a 1" or so wooden dowel rod then cutting to final shape.Have any of you done this with any success?I don't really want to try heating in water as I'm sure I'll burn myself(again). I don't own a heat gun yet and wanted to ask around before investing in another tool I don't really need or use.Thanks in advance
