   David Hughes and I both drive wedges in uder each strut to compress the 
board along its entire span. We start at the central strut then first and 
last capo then bottom strut. Then the dime quarter nickel business. I use 2.5 
mm top treble 2.25mm first treble an bout 2mmin tenor tapering to 1.5 or so 
down low on tenor. Bass is set with about 1/2 degree at the top tapering down 
to 0 at the bottom.
 Pretty much the same.
