Hi Will - Comments below: > A couple of questions, though: First, I noticed at the top of the board, treble end and just below the pinblock, is a narrow strip of wood that flares out about 1/3 of the way down from the treble end. Likewise, you have two strips of wood just above the tenor end of the bass bride curving to match the shape of the Z- bar. What is the purpose of these? > > Here is my guess: In those areas you have poor access to clamp the panel to the liner and z-bar, so these are there to serve as clamps along with screws when gluing in the panel. Is that correct, or am I out to lunch, like the dog shown below? Yeah, I think that is pretty much correct. Ultimately, it was because Del told to me do it that way! But it sure did make sense. Up the the treble area, we really chiseled out as much of the rim as we dared - to make the soundboard between the bridge and the rim (under the speaking area of the strings) as wide as possible. The piece of hard maple there makes clamping easier and also adds a little bit of insurance down the line I suppose. The pieces that screw into the Z-Bar, yes, provide clamping pressure where it would be difficult to apply pressure - one could use go-bars, but keep in mind that the Z-Bar is rather flexible down at the tenor/bass end - the screwed-in-maple pieces work very well for clamping. I guess I could have removed them, but they don't interfere with the plate, so I left them in place. Terry -------------- next part -------------- An HTML attachment was scrubbed...
