RE: Strengthening internal structures
The gorilla glue/elmers ultimate are GREAT arf beefer-uppers ! I always go in and reglue with them. They do look ugly after they swell up, and I know some people don't like that. Also you need to experiment with them to see how much it runs before it swells, and how far it puffs up. Once you get an idea it is a very useful tool. The nice thing is for some jobs you can run it down in to the iffyglue joints, position the plane to let it lay so the glue stays where you want it, then it puffs out leaving a tough but flexible gusset, just like adding tri-stock.
I had one friend get upset over this type of glue because he didn't experiment, he just applied a bunch of it and walked away, well it ran down and expanded in places he didn't want it..
