Sorry sorry sorry to hear of your troubles!
BTW - what glue will you use for the bridge?

I think titebond, 'cause I had twice a loose bridge wing with HHG. Never had that with titebond. The short working time is really an issue with hide glue.

Herman, if it's a torrefied top you may want to try fish glue. I use it exclusively on torrefied wood now.

Thanks Tim,

I wrote several companies if they would share their view on glue choice, when it comes to torrified tops.
A soon I get a decent answer, I'll post.

I once made a phone call to Bourgeois Guitars and talked to one of the employees about this. I related to him that fish glue had been recommended to me and I wanted to know if that was their practice as well. He answered "Yes, among other strategies." He did not tell me with what those 'other strategies' were.

That being said, I"ve read a number of reports of successful TB original use on torrefied wood. I'm looking forward to hearing what other companies say.

FYI, all of my glue failures with torrefied tops came using TB original. I wish I knew why but I don't. Since my last failure I have used fish glue exclusively on torrefied wood (tops and braces) with no further failures.

That's good info. I've had a partial bottle of fish glue in the fridge for 2 years, I"ll be using it for bridge gluing on this torrefied Sitka top. I should have used the glue for the braces as well, I suppose. Live and learn.

Stewmac:

"If refrigerated, Fish Glue has a virtually indefinite shelf life. The cold prevents bacteria from forming, but also causes the glue to thicken. It needs to sit at room temperature for about an hour to return to normal viscosity."

If ever in doubt about a glue's freshness, test it on scrap to be certain that it dries hard.
