Epoxy Man Strikes Again

[Farrell]

1. Other stuff is easier to use.

OK. Maybe. But I have a relationship with epoxy. You can understand that.

2. Somehow, It ended up in the wrong place. No time to figure why, but
it needs to be fixed and cold hide glue is thermoplasty and water soluble.

Ouch, that smarts! Hmmmm. I see your point, but how hard is it to make a new soundboard? I guess I would just say measure twice, attach once.

3. Future removal.

Why would you want to remove a bridge? And if you did, I can only assume the board is going to be replaced - so cut the darn thing out.

4. Tone killer, as reported by a friend who used epoxy glue for a bridge (as an adhesive).

Hmmm. Anyone know anything about this? Or is this an offshoot of the "circle of sound" theory?

I have never glued a bridge to a board. I will be doing so soon. I know that you need good even clamping pressure when using hide glue or Titebond. I have fear that I won't get good pressure everywhere. Epoxy would eliminate that concern. Anyone in the mood to convince me that I will get a good bond by running a few screws through the board back into the bridge? Or convince me epoxy is not a good choice - haven't seen good evidence yet!
