Alternate construction with aluminum
Hi, and thanks in advance for questions and opinions,
First post here in the carbon fiber gang from a non-guitarist, non-luthier. no other place except here and am new to acoustic guitars. Straight to the point, how about a........... Billet aluminum cnc machined soundboard? Has anyone done it yet? i had to laugh at the Martin/Aluminum glue-on soundboard patent. Think of the speed of sound in a dense material from the string, nut, bridge dense deck into the wood body, no deck string tension stress, flat and will be forever. Machined from 1/4" plate into a flight-worthy hitech lightweight aircraft type structure. (did this for years) Made to the standard dred plans. I sense that this lively group will have an opinion or two. i am here in taylor town area, eastern san diego if any locals wish to audition. Audibly distinct thanks again... https://drive.google.com/open?id=1AS...1SoZfs21TxdwQH

Interesting. In the end, the proof is in the tone and the cost to a buyer. Any vids/sound clips?

Interesting..
Don't know why it would not work, except overtime maybe problems due to the differences between aluminum and wood with expansion and contraction via temperature changes. Maybe if it was all aluminum, like stainless steel body resonator guitars.

After I catch up with my wooden guitar repair and building projects, I recently considered building a guitar with aluminum top, back, and sides. I'd use wood neck and neck block and bridge.
I think sheet metal wood be simpler/cheaper than billet. I'd use 3003 or 5052 sheet. Maybe .040" for the sides and back and .032 or .025 for the top. To preclude need for braces, I'd add shape (belly) similar to a traditional flat top with the English wheeling machine. Joining by fusion TIG welding. What benefit would you realize from machined billet over sheet metal? Last edited by JonWint; 03-30-2018 at 02:26 PM. |

Hi, no sound or video clips, the phone mic quality is not recording quality,
Just pictures for now, it is going on a tour next week. Quote:
for the expansion difference, aluminum moves less, don't leave it in the sun for the sake of the wood. Epoxy glues bond it and it has not passed the ten-twenty year test, Well, the Boeings do and they use glue (3M) Cost? I can get this off the CNC machine under $100 I want to do a real veneer on top too.

Yes they did,
There have been many attempts to do it right with Aluminum Just doing it different The history of aluminum instruments is interesting. Beer cans, boats and Boeings' Yeah some space hardware too.

No finger marks that's poly clearcoat over 320 grit brushed.
Satin UV cure on the wood. Had another player rave today....

2nd this. For a solid body electric no problems. One fixes it with the amp. Maybe I’m missing something but I had a resonator back in the day.
