DIY speakers of solid/reclaimed wood?

Ok,well now I need to find out what methods are used to keep the wooden instruments and the daedalus speakers in perfect condition.
I do know for a fact that very old furniture and woodwork does require regular maintainence and repair. 

It wouldn't be my choice but I reminisce at the look of my road worn DYI birch plywood JBL 4530 scoops.

A close inspection of the underside of most every Viol table (spruce top) you'll find inlay patches holding the grain together. 100 degree heat is murder on old hide glues.

I finally sold my Pollmnn Busseto Double Bass because of the constant maintenance it required. The older it got the more it needed and I live on the centeral California coast. I'm down to the pre WWII Benedict Lang laminate and a recent Upton Bostonian.

Use a high quality water proof wood glue and screws were possible.

After googling around a bit I found out the daedalus speakers are not 100%solid wood,other materials are employed.The old wooden instruments had to have been carefully stored,maintained,and occasionally repaired.The secret to the pieces of wood used is the way it is slowly and completely dried then sealed completely.Darn,I actually had to think and learn something new today:)

Reclaimed lumber is actually a verygood  choice just liken making guitars .old lumber all the moisture and resins are dry and acoustically much tighter. Once your uusesevetal natural costs of a tongue oil , or something natural ,Not polyurethane allows the wood to breath . I prefer tongue oil in ships have been using for hundreds of years let each cost dry the finish not only is more durable ,but as a added benifit it breaths and is water resistant .
if you can get it in a natural finish you have a winner. My friend is a custom cabinet maker so I learned a lot obout the best applications.
