     I must be missing something here.  The bolt-in strut in a Steinway D is 
under compression,  at least, in every case that I have been privy to.  It 
appears that it's purpose is to resist the movement of the hitch-pin deck across 
that wide, middle, section.   The negative angles on both ends, and the 
configuration of the wedging action that they have says "compression" to me.  If it 
were to be under tension, the attachment would be a single-shear application 
of the two bolts holding it down, and that wouldn't do much.  
   Or, did I mis-read the first letter?
