What's the best method to clean up the inner walls without power tools?
Ive been working on this guitar for a while now and I'm in the last steps of woodwork. I want to get the inner walls as clean as possible without power tools. What are my options besides a broad chisel?
Most of the work was done with a Chisel and a drill.
I know this is late, but some more details might be helpful. Are we talking about an electric/solidbody guitar, or an acoustic? I don't know about acoustic guitars, cuz they seem like their own thing, but with a solid body guitar, I imagine a wide chisel to get the walls straight, then sanding by hand with increasing grits of sandpaper to just clean up the surface finish. One of those sanding sponges might be helpful.
