Workshop: Targets Acquired

I use my long soundhole clamps to "feel" around the bracing inside a guitar (using the feet of the clamp to feel it come in contact with the braces) and find places I can stick cleats along hairline cracks.

Then I mark them like this with painter's tape... and each time I get one glued in place, I take the tape off.


Hi, I bought a guitar ( cheap ) because the bridge had detached.
So, I cleaned off the lacquer that was preventing a good joint and reglued the bridge back, however in transit to myself, the lower part of body obviously hit something and cracked the soundboard right by the joint to the side, can I still use a cleat and does anybody make a clamp I can A get through the soundhole and B work effectively too ?
