Guitar repair Harmonic bar crack
Hello. It seems bar at the bottom of the sound hole is broken.
Yeah. Where the grain of the bar is distorted, it has cracked.
Can you repair?
I can do it.。
Since the direction of the crack is perpendicular to the sound board, the adhesive only does not have the strength.
There is a need to reinforce after adhering cracking.
I’m begging you.
At first I sharpen the harmonic bar after having glued together.
It is to glue a reinforcing structure.
I put sandpaper on the board which I put together and make a grinder giving a plane exactly.
Polishing the bar in the tool, create a plane.
plane came out. Be aware of the polishing Works too. Since the strength is reduced.
The cracked part we can see that there are many tar component.
All you need to do now is to bond the reinforcing material.
Thank you for your request to repair.
