Hi Barbara... and yer others what responded.

I did read the article.. and with interest... especially since I had an 
idea of my own I put up a couple years back that I'll write a separate 
post on.

All this is nice and dandy... but what about the Resonator itself... ? 
and what about that smallish 1 by 0.5 peice of sugar pine or spruce that 
connects the rim to the belly rail ?  I'd kinda like some feedback on 
the original queries as well... tho all this led to some nice stuff mind 
you.

Cheers

    Hi Ric,

    Well, you might take a look at the August issue of the Journal and test for 
    weights or riblets on the soundboard.  Or have you already tried that out?

    Remember that big 'ol Seiler grand I was wrassling with a couple years years 
    ago?  In October it's going to get at least one weight or riblet in the 6th 
    octave which is wimpy.  I tested by clamping my small Vise-Grips on the 
    bridge pins and the sound came right up.
