This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Thanks for the pics. Don't need more, was just curious. Interesting, for = sure. I see you've changed the entire rib pattern. I wonder what is was = they were after with the original ribbing? I see where you are going = with it. Seems logical. I don't know that there would be any reason to put a dowel through the = panel and bridge - why would you do it? On a compression-crowned board, = a dowel is OK through the rib if you wish because you are not relying on = the rib to have the strength to support the crown - the rib only needs = to be strong enough to resist stretching by the panel. On the = rib-crowned soundboard, you don't want anything going through the rib = because that would create a weak spot on the rib - unless of course, the = loss of strength was engineered somehow into the plan. My method of attaching the bridges, modified after Del and Ron N., is to = simply run a bunch of sheet-rock screws through the panel from the back = into the bridge. I made up a bunch of large buttons (like 30 x 60 mm) = that the screws go through first - that clamp the panel to the bridge = real nice. I get glue squeeze out all along the bridge base. Maybe its = overkill - whatever. I believe Del and Ron use regular little soundboard = buttons and leave the screws and buttons in place. I remove mine and = plug the soundboard back. Looks nice and clean. I just don't get along = well with soundboard buttons. I suppose if they are not there they will = never buzz either.
