I've never used balsa as a core material, however I'm very familiar with balsa from other hobbies. I'm thinking it may be my best bet as a core that needs to be shaped. I know I'll have to drill it. What else do I need to know that is different from a cloth or honeycomb based core?

Hi drum,
Balsa is very efficient core but probably best for flat panels, it can be shaped to a degree but due to the nature of the sheets (scremed backed blocks) it may require a fare but of filling. You could go for polyurethane foam as a core as this is far easy to shape, the choice is yours! remember though the strength of a core is the sandwich itself and not the core material used! Hope this helps!
Kind Regards
