Cedar

I can get some nice cedar wood (Cedrus atlantica). Anybody has experience building cores with that?

Maybe too late... I made two pairs with cedar. Both delaminated. I accused the cedar for it although it wasn't 100% cedar in the core. I didn't do any thorough investigation, but my own suspicion is that it is somehow "oily" or whatever it contains. In my experience not epoxy friendly.

I used it only once long time ago on my first pair, and had no problem. However, wood was well dried and probably 50 years old. I experience different problem because it was quarter sawing when router for sidewall It was easily split alone grain line
