[CAUT] Riblets: was Lack of low-frequency response

[Barbara Richmond]

Dave,

I know what you mean.  Recently, a colleague and I
did an installation, where we had to work over the action cavity --is that 
what you call it?--anyway, there wasn't much space for working.  We 
used a thumb drive of sorts to getthe screw hole made and an offset rachet 
screwdriver (without a bit, just hex drive, Pianotek, #CM-13K) to get  hex 
head screws (that I used in this instance) in.  Those tools made the 
installation possible, but it still wasn't easy.
