John, Is the piano strung or unstrung? Use wood doughnut screw grommets that hold the bridge as a benchmark to locate new holes for screws to hold the bridge in regluing it. try to align the new screw holes so that the screw will go into the rib. Counter sink the screws so that the string does not make contact with the new screws. Apply glue and use the screws to clamp the bridge back down. Joe Goss ---------- From: John M. Formsma <jformsma@dixie-net.com> To: PianoTech <pianotech@ptg.org> Subject: separated bass bridge Date: Sunday, March 07, 1999 2:08 PM Greetings, All. I have searched in the archives, the PTJ's that I have access to, and the Reblitz book; but have not seen instructions on how to reglue a bass bridge that has separated from the soundboard. The piano is a BOU (big old upright), and the bridge is completely separated from the soundboard. The only repair procedure that I've seen that comes close was described in the Reblitz book for repairing a loose soundboard rib. 1/4" holes are drilled thro soundboard and rib, into which are placed threaded rod with washers and nuts (to act as clamps). After glueing, the bolts are removed and dowels are inserted to replace the rods. Would a procedure like this work for a bridge as well??? Any other ideas? Thanks in advance. John Formsma P.S. The piano may not be worth the repair, but in its present condition, if I botch it, it is no great loss either.
