So I finally getting around to building my first Ukulele. I bought a raw material kit a few years ago and all of the pieces have weathered fine.
I constructed the back and the sound board using a go go cage type of set up. No problems there. However after removing both parts with all components glued and looking great. The back and sound board have cupped?
The cupping started after I shaved down the tone bars. They are still a little rough but close to what they should be for assembly.
The cupping is happening towards the exterior mostly on the tail side.
So I ask why?
The back and sound board are Koa, extremely ugly Koa but it is my first build so I figured why not.
I am not blaming the wood
Since I was in the process of getting these panels to thickness I resawed quite a few of panels for future use. They are very close to the thickness I desire and there all dead flat after glue up.
I do not want to repeat this cupping in the future so any help would be great. Thanks in advance
