Classical guitar repair, Vincente Sanchis, model 29, made in Spain.





Yet another Peg head break that has been previously (and poorly) repaired.

I took a pair of tweezers and carefully removed all loose shards and splinters of mahogany
from the break. There was a deposit of hide glue on all the surfaces
that needed to be chipped off as well.

The neck was given the same treatment. Most of the Hide Glue was deposited on this side of the
previous repair.

This is the weekest point of the classical guitar neck. Sapele Mahogany is not particularly
strong in this application. The way the neck was cut from the balk of timber meant that the
grain ran across the weakest point

Though the label gives no details, some research on the net showed me that this is a
Classical Model 29 from the 1970's.

Work begins on the repair. There were several splits in the surface of the peg head that
needed to be glued before I could repair the main break.

I have a pine wedge that serves as a caul for the sash clamp which puts direct pressure on the
broken joint

Here you can see the sash clamp pulling the break closed.

Close up of the peg head with cauls and clamps to prevent the peg head from splitting under the tension of the sash clamp.

I glued a piece of Burl Sapele Mahogany over the peg head to conceal the ugly glue line.

The break is already hard to see.

3 coats of acrylic clear lacquer and tuning pegs fitted.

A reasonable result.

Guitar looks like new again.

My guitar doesn't need repairing but that burl covering the glue line is so good I might have to think about doing that to my Sanchis 29 for the beauty of it! Great job.
