Last night I broke a scrap of maple and glued the broken pieces back together supporting them with a patch of linen soaked in hide glue. This morning, the glue set, I could not separate the crack try as hard as I could. SUCCESS, this old luthiers technique works.
So today SOAGB is lashed to the operating table and the treatment is about to begin
The operating tools are assembled, An inspection mirror with lights, a glue brush extended with a long dowel, a long pair of tweezers, scissors, Titebond hide glue, and a swatch of linen from the fabric store.
Now we survey the injury. you can see the new crack just above the old circular patches from the earlier break. It extends to the right ending at the vertical side brace. You can also see the dark hide glue put into the crack a day ago from the outside. It oozed through the crack and hardened, a good sign that the crack is sealed.

With the long brush, hide glue was painted over the wood surface. linen patches were cut and set in the wet glue and then more glue was brushed onto the linen saturating it with glue. It isn't very pretty but I think it will be very effective and Son Of A Gut Bucket will play again.
