Hi Richard, I haven't read all the posts of this thread, but I have read a few. Although I can't see any reason to think that the centripetal tension resonator would have any significant impact on crown maintenance, I don't necessarily think of it as useless either. In my primitive thinking, it ties together the various sections of the rim structure even beyond what the Mason & Hamlin's massive inner and outer rim and beam structure goes, making it an even stronger (and more importantly at least in my mind) more rigid sub-assembly. By tying it all together, it would seem to me that stresses on a small area of the under structure would be transfered to other areas in a "share the load" kind of thing... might even be an expanded version of the plate horn, where the horn is tied into the belly rail to add support to an already fairly strong plate structure. That's my general thought on it, and indeed opinion. Best wishes, Brian T. ===== Brian Trout Grand Restorations 3090 Gause Blvd., #202 Slidell, LA 70461 985-649-2700 GrandRestorations@yahoo.com __________________________________________________ Do You Yahoo!?
