- This guitar had several cracks in the top, back and sides. They all needed attention at some point, but we chose to start with the ones on the soundboard. This video primarily shows the work we did on the ugliest crack, which was not only long, but it had an area that had been severely compressed by some sort of blunt object The compressed area had to be pushed back up to the surface of the soundboard with a little loss of wood splinters as possible. After some experimentation and dry runs, we ultimately used a small scissor jack to push the damage up from the inside of the guitar.
sound like a very nice work environment
It is!
Excellent video. Very informative.
Thank you!
This is interesting. May I ask; my classical guitar has a similar crack, but I've been warned against using lateral force with a similar clamping technique. Would there be a difference between my rather slender classical and this country-and-western guitar in this respect?
@hni7458 You need some way of pulling the piece together and i think clamping works quite well. The important thing is knowing how much clamping force to use. Whether it's a steel string or a classical, you want just enough pressure to pull the pieces together.
The gap in that crack seems pretty large. Stuffing a bunch of glue in the crack won't do very much if you can't close up that crack. It doesn't seem like those clamps will close the gap.
The clamps did close the crack completely, and the area that was pushed inward was stabilized by the large patch on the inside. If the crack hadn't completely closed up, I would have put in a splice of wood because you are correct, we don't use glue to fill a void.
@@zimnickiguitars311 ok. At the end of the video it didn't look like it was going to close up. I guess i had to wait until the next part.
