Remember, at this point you are dealing = with a bridge that is not yet planed down to it's final height. You = prestress the board, cut your notches in a few key areas, remove = everything and plane down the bridge, mark, drill, notch, etc... On a = new board some do this with a dry fit, before the glue in the board = itself. That way the planing, drilling, pinning and notching can be = done outside the piano where there is more comfortable access.

Just use the half = with the fire hose. Clamp it to the rim above the bridge, inflate, and = there you go with measurable pressure applied all along the long bridge=20 ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
