<table cellspacing="0" cellpadding="0" border="0"><tr><td valign="top" style="font: inherit;"><div>I do agree with you, David!<br /> Thanks for all the info. I'm too fatigued to assimilate it all at present (it's 12:09 here -- AM or PM depending on whom one asks-- I call it AM) and all I further "figgered" is that a "dead" plate will, besides not augmenting partials, also not transmit vibrations itself very well to the rim. So that eliminates some factors; leaving scale, hammers, and belly design (3's plenty!) to work with....... unless I'm forgetting something...<br /> (Like I said ---it's time to go to sleep.)<br /><br />Thumpe<br /><br />P.S. I recently moved 2 Conover 77's (much like Masons) both "vintage", but one had an AMAZINGLY fat bass side (like 7-1/2" thick!) while the other was more like 5". Too bad I didn't have them both strung and side-by-side; but the 7-1/2" thick one had a GREAT
bass!</div></td></tr></table> <div id="_origMsg_">

Warm can also mean a bit stingy. I would prefer something a bit freer and I think the bridge and its size gets in the way of that somewhat. A bridge that lacks adequate height can also be a problem (though at the other end of the spectrum) and I’ve seen Steinway bridges that were very short at note 88 that benefited from being made a bit taller. OF course that requires some plate elevation changes and such but it doesn’t take much. Ron’s right, these aren’t calculations, just dead reckoning. </span></p><p class="MsoNormal"><span style='font-size:11.0pt;font-family:"Calibri", "sans-serif";color:#1F497D;'> </span></p><p class="MsoNormal"><span
style='font-size:11.0pt;font-family:"Calibri", "sans-serif";color:#1F497D;'>Heavy dead plates are good things as are solid, heavy rims. Higher tension scales can be dealt with by properly designing the rib scale. The bridge adds some stiffness and unifies the assembly and distributes the load, but it doesn’t need to be that big, at least I don’t think so. I think the tone will be improved: more expressive, wider range of dynamics, livelier and freer sound. But that’s just my opinion, others may not agree. </span></p><p class="MsoNormal"><span style='font-size:11.0pt;font-family:"Calibri", "sans-serif";color:#1F497D;'> </span></p><p class="MsoNormal"><span style='font-size:11.0pt;font-family:"Calibri", "sans-serif";color:#1F497D;'>David Love</span></p><p class="MsoNormal"><span style='font-size:11.0pt;font-family:"Calibri", "sans-serif";color:#1F497D;'>www.davidlovepianos.com</span></p><p

(I should have put "calculations" in quotes.) What I meant was "mental"
calculations: figgerin', flossiphizin', stuph like that....... (All I'm good for --- numbers scare me!) This thread just got the marbles bouncing around... but not really knowing where to go....... <br><br>So you have an ultra-dead plate, strung at a relatively high tension, over fat, impedance inducing bridges, on a CC board, on a beefy case....... and it all somehow adds up to that warm, rich, Mason tone....... (albeit with a board that splits like crazy, eventually) and the goal here is to improve on that. (Which I'm certain can be done!) Hmmmmmm... I'd just really want to contemplate all these complementary and countervailing (some, perhaps, by design) factors, before I tried anything...<br><br>Thumpe</p></div></td></tr></table><div id="_origMsg_"><div><p class="MsoNormal"><span style='font-size:10.0pt;font-family:"Calibri", "sans-serif";'> </span></p><div><div class="MsoNormal" align="center"
