Question? If I built a body from scratch, that’s the minimum thickness I should go for? I was given a 100-year old piece of spruce planking at 1 1/4” thick and 24” wide, lacquered on the front and back. It’s tongue & groove from an old pipe organ air box. I’m building a lap steel from it but still have a 38” long section. Thought about a super lightweight bolt on, in a Tele shape, but it doesn’t leave a lot of meat for the neck joint. Thinking I might plane it to 1” and put a thin cap, and if I go that route, I’ll probably chamber it to make more weight savings. But if you think I could go this thin, it would be neat. Might have to take 1/4” off the neck heel thickness and use shorter screws to make it work. I’ll be using a Hipshot hardtail bridge I already have in my spare parts box.
