I've got what I call tear out because I can't think at the moment of the right term - when I bent my side (well, fwiw, we're actually talking about an a-style mando rim), I did so slightly too agressively in a couple of places and small sections of grain tore loose from the surface - not full- on cracks or breaks, but I've got to do something with them. My instinct is to use CA and then sand down. I've got plenty of thickness in the rib to do so. Is that pretty standard operating procedure? |

I assume this is maple, yes? And it sounds like what I call flame lifting. (though that is probably not even close to the real name) Yes, you can lay it back down but I'd recomend using white or titebond glue. CA might sort of highlight the lift. HHG will also work very well. |

What Paul said is the right thing to do, Jay. Also, I would clamp them with hardwood cauls shaped with the same radius as the side where the break is. (inside and out) Wrap them with wax paper and clamp them pretty dern tight. You probably wont have to sand very much at all. long |

use Hide glue or white glue not CA, and clamp them back into shape. Sand them and you should not hardly notice it. If you use CA on Maple for this it will stand out horribly. CA works well in this situation for dark woods. edit..I just noticed I just repeated what others have already said...oh well.. |

It's actually sapele. This is my mando-out-of-what's-laying-around project...basically all mahogany. |

CA will still show way too bad in Mahogany...go with hide glue for the most invisible repair. |

Any chance commercial liquid hide glue in a bottle will work similarly to regular hide glue in terms of effectiveness and invisibility? I typically use white glue for my builds and am not set up for hot hide glue. Thanks for all the advice, I really do appreciate it!!! Jay |

NO. the "liquid hide glue" stuff is not good at all. Use your white glue. Make sure the peeling closes all the way up so the glue line won't be noticeable, and you'll be fine. |
