Hi John, David and Ron. This is not a one piece plate and plate bolts wouldnt work on this instrument. I could shim the back plate up but that ends being just about as much work as shaving down the bridge a bit. Its a solid bridge with no cap except in the top 30 notes. David and Ron. If either of you are under the impression that I have any objections to the RC&S methods then I dont know what to tell you. My objections get into gear strictly when people start making comparisons between methods and means that are off topic to begin with and clearly negative in character. I just got into it with one of your counterparts.... you might say one of your betters in at least one sense of the word... since the fellow is actually running a successful factory in Germany. He is on the opposite side of this RC&S vs CC thing. And his snearing at non CC boards was every bit as unproductive and inappropriate as many of the comments against CC boards I hear around this place. And, as you can probably expect if you really know me at all... I got every bit as provoked as I usually do. It gets tiresome hearing how the other guy sucks all the time when all you want is some hard argumentation for why this or that or the other thing is what it is. It matters not which side its coming from as far as I can see. Calculating soundboard deflection in this case could not account for the error David, since I ended up with more string deflection then I figured. There was a procedural problem here that had to do with a difference between the soundboard and bridge being screwed and clamped into place and when the assembly was finally glued into the rim. The thing ended up higher. Here... in this question... I just wanted some thoughts as to what went wrong with the procedure I actually did use. And what to do about it. Not a lot of need for any controversy here, not a lot of need for anything except some friendly professional advice...which is what we are supposed to be all about here IWUTI. And indeed... a few onlookers were kind enough to send me some encouraging thoughts off list. Cheers.
