Hey guys I have 1930 Harmony guitar that plays and sounds amazing absolutely love it. I found it at an antique store in southern Oregon it has some pretty big cracks along the back of the guitar and to get it fixed at a luthier would be pricey. Any advice on home repairs would be awesome. Someone told me to get hide glue and mix a little bit of sawdust in with it and clap it down for a couple days while it dries. Anyone have experience with this?
