adapting materials & methods of homebuilt aircraft

Hello, I've been thinking about building again, and looking around for innovations in materials and methods. In the past, I bought spruce wood offcuts from Aircraft Spruce for building acoustic guitars, and while visiting the website today, it occurred to me that the homebuilt aircraft industry might be of interest to TD builders. Here's a link to 'how to' articles about the construction and covering of homebuilt aircraft. I think there are useful ideas to be found here.
