Any thoughts as to whether this is a terrible idea? I tried applying downward pressure and sure enough the wood glue joint separated at the end grain joint. Then I put some CA glue in the joint and now its not budging when I apply similar downward pressure. I think the CA glue is pretty effective on the end grain joint... String tension will pull it the other way and strength should be fine. Only risk is how well it handles an accidental drop or something. Don't ask how I got to this point... Total headstock thickness is 0.55". Base wood is .26" maple with the .29" top sandwiched on.
