Center Seam Separation

[kaspforeva]

I have a guitar with a center seam separation occurring on its top. I am trying to find information on the proper way to repair it. Do I use cleats? Do you re-glue it, and if so, what type of glue to use?

The first thing to do is hydrate it. Many times the seam closes on its own once it is properly hydrated. Once it is hydrated, I would cleat it to stabilize it.

I don't think hydration is the cause for the problem. The guitar has just come from Japan where the climate is humid.

Pics would help a lot.

Steel string or classical guitar? Is the crack through the bridge? All the way to the tail block? Across the bracing? And so on...

Hydration is always the cause of a signification seperation in the top behind the bridge.

To much or too little will split that join every time.

Once its split you cannot just simply clamp it back together you need to climatise it correctly, this allows the alphatic glues that hold the braces in place to creep a fraction and allow better alignment of the book match join.

If after stabilizing it is still split then you have to conduct a thing called a splint repair, which is where you insert a piece of wood in the gap
