Getting things drawn out for my first build. Decided not to go with the cigar boxes I have. Most are cedar veneer over particle board. Kinda disappointed but they wont go to waste. I do have a couple that are or at least look solid wood. I'll save them for later. Going to make the box out of 1/8 ply savaged from an old dresser I got off the street on trash day. The neck will be 2 piece maple from the same dresser. These folks have cats. The smell will travel farther and faster than the sound....LOL The bottom of the dressers will have to go.
Here's my plan that will lead to my question.
The only structural support for the top of the box will be two long thin bolts imbedded into a small piece of wood going from the bottom of the box to directly under the bridge.
What I'm thinking of doing is using nuts and locking washers to suspend something off this assembly. The sound traveling from the tension under the bridge would travel threw the bolts and into the resonator.
My questions. If I suspend something inside the box will it make it louder? Wood or metal? The inside of the box will be 10 3/4 x 7 3/4. Anyone have a formula or idea as to how big or what shape would create the best sound?
