Kind of fun actually. Remember Mason & Hamlin's old >sales gimmick with the strip of soundboard material and business >card? If a board can be moved but a few thousandths of an inch it >can lose crown, I think. Sure it can, but not by moving the perimeter support, because the perimeter isn't what's holding the crown in the first place. As long as we are on demos, try that old Fandrich demo (that's the old demo, not the old Fandrich) of wedging the rim of a grand in or out a bit and see what, if anything, happens to the crown. We've been through this already a couple of times in the past, and soundboard crown still isn't an end supported arch. > it >is amazing the we don't have more flat boards than we know of. We have many many more flat boards out there than any of us know of. Actually, a flat board can still be ok functionally. What I mean is negative crowns that are supposed to be positive. If we checked everything we tuned, we'd probably be appalled at the percentage. It's just that nobody, including me, normally, checks crown unless the customer has a complaint about the sound of the instrument, or the tuner notices something awful. Even then, most techs won't check the crown, or will only check it at the longest rib ( in an area of the scale where the problem isn't ), and assume it's a hammer voicing problem. >PS Ron has installed many more boards than I (2) Right. and is brighter than me (IQ?)
