Seeing everything come together for the double top is exciting! I've been looking forward to this video.

[@RoneiRamos]

Cool! What do you think to use balsa wood in place of nomex?

[@geomariland]

also cedar? I really want to know the difference between a solid cedar top guitar and a cedar-cedar-cedar double top guitar (the core pattern depends on the maker’s choice).

[@schrammguitars]

I think Nomex sounds better. Balsa is much weaker and less resistant to tension. Once it bends it goes into failure.

David, I watch a lot of guitar building videos and have not seen anybody else using Gorilla glue. Most folks use PVA, hide or epoxy adhesives. Could you please explain the logic behind your choice?

[@schrammguitars]

I've never seen a double top with Nomex built with PVA or hide glue. That makes no sense. Who builds Nomex core double tops with those. I'd love to see their videos. Matthias Dammann told me to use Gorilla glue many years ago. Gernot Wagner uses it, Greg Byers used it, I've been using it for 20+ years. I don't use it for everything, only where it's properties excell. It doesn't add moisture and cause wood to expand. It is heat resistant for bending parts that you do not want to move when heated etc.. I use it for Fingerboards, Neck joints, laminations, rosettes, purflings, oily woods like cocbolo,...
