Thought I'd run this post through the board for a second time as it previously had no responses.

~*~*~*~*~*~*~*~*~*~*

A few minutes ago I opened the hardshell case of my near new concert Kala Cedar top uke to rehydrate it's humidifier. To my horror, I saw that the bridge had popped off. OMG ! Fortunately, the damage caused by the seperation was restricted to only the wood directly under the bridge - a paper thin layer of cedar was stuck to the bottom of the bridge. Apparently the glue was stronger than the wood.

Although I won't be attempting this repair myself, I am wondering if I should have my luthier not only glue the bridge on, but somehow also pin (or rivet) it back onto the top. I am worried that, with just glue, if it should ever pop off again it would pull even more wood off.

I am wondering how this type of repair will affect the sweet tone & tuning of my Kala. I'm also curious about the cause of this problem so's I can prevent it from happening again.

Any input or opinions will be most gratefully recieved.

Hey Jerry,

If you can get the bridge back on "exactly" where it was, including the wood that ripped off with it, go for it.  Pops off again, take it to a luthier.

Not a uke expert, but, 4 nylon (?) strings can't exert a whole lot of tension.  Use a good carperter's "yellow" glue and see if you can get a C clamp into the soundhole to clamp gently (using a cawl so as not to damage the bridge and to apply even pressure across the bridge)  while the glue is drying.  I'd leave it clamped overnight.  Not too much pressure, just enough to squeeze a bit of glue out from under the bridge.  Clean this up before it drys.

But, if attempting this makes you uncomfortable, or if you feel it should be screwed on as well,  take it to a pro.

Mike

Thanks for your response, Mike.

I've decided to let my luthier (Palm Tree Ukulele in Colorado Springs) reattach my bridge. I will also leave the descision to them of whether or not to pin the bridge to the body.

I've had a very reliable source (who I shall not name) tell me that the Kala Cedar top models may be going to a "screwed system" in attaching the bridge to the body. Makes me wonder if this seperation isn't a more common occurance. A set of very short (3/8"), light and wide screws will not add enough mass to the bridge to stifle the volume.  

BTW/   I reposted my query to the "General Ukulele" forum where it got several responses -    http://www.ezfolk.com/forums/forum19/4889.html

Thanks again,

:dance1:
