This is a first for me. How would you guys approach removing a damaged bridge plate that was glued on with fish glue? |

Closed instrument? Bridge on? Does it really need removal? There are ways to fix string ball damage without removing the plate If it's a top not on an instrument yet, I would just plane it down to the glue and scrape. Is the center seem fish glue? Fish glue should turn loose pretty easily w/ moisture. I've had great success with hide glued maple by sitting a moist sponge cut to the size of the plate with the instrument face down. I put a piece of plastic on top of the sponge so more of the moisture goes into the plate instead of evaporating out the other side. I don't let the sponge contact any surrounding braces. leave it all day and check every few hours to see if you can slide a thin spatula or feeler gauge into the glue line. I might take 8 hours or more. Thanks to John Hall of blues Creek for this method. If that's not enough, I break out the hot chunks of plate shaped aluminum screwed to a bridge clamp and the excitement begins. |

Thanks David. John was actually nice enough to share that technique with me on the phone yesterday, and it worked a treat! Sponge overnight, heat blanket this morning at 150 degrees, it pried off in about 2 minutes with no damage to the guitar whatsoever. Now I'm going to let everything dry out fully, scrape any residue and get a new plate in there. Big load off of my mind! |
