I know I said htis before, but I am a novice at reapir etc. I do it to my own guitars as a hobby, so my questions may be rudimentary to you guys.

Anyway I have an acoustic that a number of the top and back braces were knocked off in a fall. I just thought I'd clean up the residue glue and re-glue. Any tricks for holding the drying braces in place other than long clamps?

Also, any idea why those old Gibson LGO's - I think they had ladder bracing - all have the bridge pulling up. I have one where I re-attached a new rosewood bridge (the braces seem fine) but under normal tuning the bridge pulls up the top. Is there a fix to this? More braces -- but don't I then change the sound?

Thx

I have a couple of these:

They work very well in places that you just can't get a regular clamp.  The biggest 'secret' to regluing, IMHO, is getting the old glue cleaned out of the joint before re-gluing.  Getting your hands on Dan Erlewine's "Guitar Player Repair Guide" is a good place to start.

Never messed with old Gibson's so I can't help out there.

thanks guys

It is an x braced Signa (Martin import I think - Canada). What kind of glue was used I really don't know. The braces that came off were the 2 X's and one shorter brace.

Thanks Jim I will tell you how it comes. But since I have you the fall created two 4-5 inch cracks down teh sound board on the lower bout - below the bridge. Do I need to do anyhting else there besides put the braces back below the cracks and drop some glue in the crack?

Dennis--

Michael has brought up a very good point.  If you are willing to look at this as a learning experience and no one involved has too big of an emotional attachment to the guitar (just in case things go south).

With the Sigma (and I have to go with a shaky memory here), I believe that the back is not bound.  If the damages are such that you need unfettered access to the bracing, I'd consider removing the back with heat and palette knives.  You can then have relatively decent access for the repairs.  Spend some time out at Frank Ford's site http://www.frets.com to see pictures of these types of repairs to see if this is what you really want to do yourself.  Its probably not economically feasible to have this done to a Sigma by a luthier, but if you are willing to risk the guitar being turned into a wall hanger, its worth the effort in learning some of the skills.  You may want to consider getting a $25 Harmony from e-Bay for a practice run when it comes to removing backs or tops.  Good luck -- repairing this stuff can be fun when you are not under the time restraints of trying to earn a living!

Thanks guys. The guitar was given to me and I am doing the work simply for the experience - so however it comes or not is OK. I would never touch a really good guitar.

Anyway, it was only really one full cross brace and half of the second, then a ladder brace in the front ahead of the soundhole. I was thinking I would scrape out all the old glue and use titebond. To hold each brace in I was thinking of a combination of clamps (I have 2 bridge clamps) and then making  a few 1in square supports about the depth of hte body - a bit shorter - then attaching a small light spring to the end - I think I saw something like this in Dan Erliwines Guitar Repair book.
