I've noticed my guitar soundboard seemd to be belling up a little. It's the one in this picture. Not that much - it's still playable, but I'd hate to see it explode on me. I'm very fond of the guitar, which I found in a fairly bad state in a charity shop a few years back .

So I'm thinking what I could do to sort things. One idea is to fit on a tailpiece, so that instead of pulling up on the soundboard the strings would be pushing down.

Anyone ever tried doing that, and did it work out ok?
