Hello all
I had to deal with a delay, but am starting a project with a wood wing. I know the conventional wisdom is just to use T-88, but I can never leave something like this alone. Besides, I have grown to dislike epoxy from boatbuilding and have gotten sensitive a bit. And one of the things I worry about, heat, affected the epoxy in my boat project. In reality I would use epoxy and may, but I'm finding interesting stuff as I challenge epoxy. For one thing I see absolutely no reason, or even no excuse, not to use resorcinol for the spare. I've found a resorcinol that has minor gap filling ability and why wouldn't I be able to properly clamp it up. An in place repair might be a different story. I do see evidence of titebond being a poor choice due to creep. It seems like a concern with foundation. There also seems to be a cause for concern with Weldwood Plastic Resin. I am pretty much to the point of writing it off. But again, the deeper you dig the more you see that there are different varieties of all of these products. There may be better formulations of UF glue with just a bit less press and notoriety.
But the point of the post is to put this article up for view on the subject of epoxy. It's a bit old 1997 from the forest service. But it actually references aircraft construction and talks about a product that may address some of epoxy's shortfalls. For those that think erpoxy is perfect it suggests it can be made better. I haven't even started to see if it can be obtained. But I thought I'd see if anyone has heard of it and if not, does anyone find it interesting.
I apologize for posting about glue. I know it can be a real hot button.
