Put the piano up on its side. Look for any soundboard to rib separations and draw them together using screws as others have described. Vacuum and dirt off the top of the ribs and around the soundboard rim. Spray CA accelerator along all the rib joints and around the rim. Wait 20-30 seconds (this lengthens the glue set up time allowing a little time to absorb into the joint). Then apply thin CA to all the same joints. First, do the rim joint at the top while your bottle is still full. Squirt the glue vertically up into the joint. The capillary action of the glue will actually suck it up into the joint if there are any voids. Then apply at the top of the rib/soundboard joints and allow it to run down the rib. You will see the glue absorb in where there are voids. You may even see it run all the way through the rib and come out the bottom side. If that happens spray accelerator directly on the spot to form a dam and allow the joint to fill with glue. Make sure the glue runs all the way down the rib to get the entire length covered. Do all the ribs, then the rest of the rim. Let the piano set for a few minutes, then spray accelerator over everything to make sure all the glue is set up before uprighting the piano. Otherwise if the glue has pooled somewhere you may get a surprise. The entire job will take one to two ounces of glue. -- Dean Dean May cell 812.239.3359 PianoRebuilders.com 812.235.5272 Terre Haute IN 47802 -------------- next part -------------- An HTML attachment was scrubbed...
