Location: Utah | Thanks in advance.
My 1776 Patriot has several loose braces, which explains the belly it has developed. One is loose almost the entire length from the sound hole, running under the bridge, to the far end. Two others are loose for 6 inches or so. One other may have a short segment loose.
This guitar is deep bowl, center sound hole. No access hatch in the bowl.
What type of glue is recommended? Wood glue? Diluted wood glue? Epoxy?
How would you apply it? Syringe?
Any hints on clamping?
Are the StewMac soundhole clamps the tool to use? How about the brace jack, anybody recommend it instead of clamps? http://www.stewmac.com/shop/Tools/Clamps,_support_tools/Brace_Repai...
Should I loosen the truss rod until I get strings back on?
Am I nuts to take this on? Is it more complicated or tricky than it looks like it should be?

Location: Upper Left USA | The truss rod is fine.
Clamping is preferred and white glue or cyano but the access issues are the real issue. |

Location: Pacific Northwest Inland Empire | I just put a dab of Woodbond on the end of my finger, work it under the brace, then use a long-reach clamp, with a bit of waxpaper on the contact pad, to avoid sticking the clamp to the brace. Do them, one-at-a-time. Don't know if that will eliminate the belly, though. You may need to remove all the electronics, bridge saddle, & anything else, dampen the tone board on the inside, and put some weight on it, for a few days, BEFORE you attempt to reglue the braces. The wood has a memory, and may return to it's original plane, with a little encouragement. |

Location: Pacific Northwest Inland Empire | FYI, the clamps I have, look like these, except they have about an 8 inch reach.

Location: Thredbo, NSW, Australia | When I had to repair my 1614 I made a clamp out of a small turnbuckle.
I cut one end to fit around the brace itself and slipped a rubber foot on the other end. It's easy to adjust with one hand and worked very well.

The soundboard has returned to flat after 24 hours with no strings. Good news!
Using a thin feeler gauge I was able to verify 2 of the braces have separated from the sound board along almost their entire length. I am optimistic repairs will be fully successful in reversing the deformation which appeared over the last couple of months. |
