I was looking into the thermodynamic equations to try and figure out how close I can be to the wood, to start to burn it, and I realized that it's probably way easier to just build and try, than account for all the variables. I won't run it for very long anyhow, I don't want to risk damage to customer's amps.. it's just gotta work for testing.
Sure! If it gets too hot you can always use 2" standoffs instead of 1". Air is a good insulator.
