[CAUT] Killer half-octave

[Daniel Gurnee]

David,

I have, on my S&S O boosted the killer areas by increasing SB bearing 
by 0.001-0.003 with a wood/springcleat bridging the beams with a wedge 
between the cleat and the appropriate rib.  Another help is the adding 
of five lbs. to the equivalent of the S&S D and B bell area to diminish 
plate flexing there.
