Larrivee glued their bridges with CA/superglue?

[dermot]

From UMGF;

That Larrivee glued their bridges with CA/superglue directly over their polyfinished / catalyzed tops is neither false, nor a rumor.  Larrivee, & several Asian import makers use, or used, this method.  This has been discussed here some time ago, on MIMF, as well as the Larrivee sight. It has been both confirmed & denied by Larrivee themselves. I gather that Larivee used to use this method, but stopped some time ago.  I believe that Mario Proulx  took part in some of these discussions.  My situation would tend to support the feeling that this method doesn't hold up very well.

What I can't verify is whether MY specific Larrivee Parlor's bridge was glued directly to the poly finish with superglue. Assuming that it is (better than a 50/50 chance) - I simply want to find the BEST way to remove a bridge that has been glued directly to the top's poly finish with CA/superglue. I need some direction from someone who has actually done one - or better yet several. Cutting off the bridge with a router is not an acceptable option.

Anyone heard of this?

I've never seen it or heard about it.

Cyanoacrilate would not be my first choice since it does not have the best shear strength, but it is not an unreasonable choice for gluing over a poly finish.

pics from the forum III build, maybe helps explain the current process anyway.

A picture is worth a thousand words...nice Forum III pic.  That's enough for me.  Why must we always over-think things?  If I could tell the parlor owner myself, I would; "Just play the darn thing and quit obsessing over it!  If your bridge is coming up, have a good repair guy (or gal ) get it off and reglue it."  Done deal.  That's sounds easy enough to me.  CA glue?  That's a new one to me.  It makes no sense to use it for this application.  In fact, it would be stoopid to use it to glue a bridge unless you were making a FirstAct guitar from China for a 3 year old to beat upon without mercy.  OK, rant over

Having handle Larrivee's for over 10 years now and having reglue about a dozen or so out the hundreds I've never een one glued with stupid glue.Its very hard to get stupid glue to glue wood as the wood absorbs so much and then it doesn't even hold up to the tension.I just did a glue up on an Olympic which was held on with stupid glue to the finish.It took about 30 min just to remove that thick a** finish from the top of the guitar and another 30 min just to get to wood on the bridge that was covered with the stuff.

maybe a stupid question, but does the finish adhere to the wood enough to stop the bridge, stupid glue and finish together from becoming detached under tension?

I have no idea! But it is a good question. Jeremy, Uncle Rob?

Ben not as long as wood to wood with wood glue.Wood to wood in most case's will lift slowly.Stupid glue had a clean break from the finish popped right off as the guy was playing,in his case minimal hand and guitar damage occured.

  Good posts, and I never use stupid glue for wood to wood like a brace etc. Just the tiny cracks or special touch up stuff. I'm learning a lot from the forum and then putting it to use with some of my projects.

If you are asking whether a bridge glued on top the finish can tear the finish off... it's more likely that the glue will give before the finish releases from the wood because both the finish and glue should adhere to the wood better than each other(which is why gluing to the wood is generally preferred).
