I've been working on a Simple Scout, and got to thinking about cleaning up (tidying?) edges. Got out my trusty covering iron and grabbed some scrap pieces to ruin try. After trying a few diferent settings, it looks like 155C gives good results with Adams readiboard. This also fuses the edges as it melts the foam. See the attached pictures. I think if the iron was much hotter, the paper facing would scorch, so be careful. Also, thin edges seem to get almost brittle, so a small edge radius would be better than a knife edge. When I get it into the air, we'll see how this affects durability. Give it a try - don't get burned!
