I designed the interior, and marked it out with a sharpie
This is getting a Pig Tail wraparound bridge, so I left a bit more wood in the bridge area. I left more in the tail section to help with weight, balance, and resonance. The barnwood weighs almost nothing, so the ash will determine the balance of the body. I don't want a neck diver, so this becomes important..
Once I cut out the chambers, I set up to attach the back. Lots of clamps, glue, a damp rag-- the usual suspects
I dampened the wood, to open up the pores
then applied plenty of glue
