Dan, I've got an aftermarket case for Ovation deep bowls. No idea where I got it or what guitar was in it. It's empty now.

You can have it if you want it.


Thanks, Paul. I'll take it! I don't need it right away. It'll be for the 1111. Bring it with you the next time you come over.

Did some detailed analysis of the bowl today. Suffice to say it has "issues" Quite a bit of warping has occured along the top edge. Cannot be flexed out with pressure. Going to take an awful lot of work to get this right.Close to 1/8 in a couple spots. Hmmm, is it worth the effort? Especially with the busted bowl work?

Since it's a hand-laid bowl, you can perform a bowl-bend to fix the warping.

Basically, I would clamp the bowl as you've done, then apply heat in the form of IR heat lamps or a heat gun. I've done a bowl bend with a heat gun. IMO IR heat lamps would heat it more evenly.

It's going to have to be heated to ~250° before the epoxy reaches its TG temp. (TG = transitional glass temp = temperature where the epoxy becomes rubbery, once it cools it will take the new shape)

Hi Dan,
Yeah, I have done warp removal before. Pretty time consuming, especially with the multiple warps and other problems. I am considering the time effort of repairing this run of the mill Balladeer vs the sale value after it is done. If I was dealing with a higher level Ovation, or a rare model it would make a difference. With the multiple warps there is a chance of loss of correct shape, so i would need to build an outline form. More time lost from other money making projects. I had a form years ago, but gave it to another luthier who was getting a lot of O repairs during the eighties. I had backed off of doing O work to concentrate on vintage other brands. Not doing as much now, getting older and lazier. LOL Guess I will have to make up my mind one way or the other. I do love my Ovations but can't keep every one I repair.
