So many people have made this, or similar, comments in this thread that I 
have found it needful to comment/ask a question(s) in spite of having 
promised myself in the past that I would not do so......
 
Does anyone have any "objective" evidence that there is significant (meaning 
tuning altering) pinblock movement after intial tensioning of the 
strings....since the talk is of "wedging" between plate flange and pinblock 
it is movement in this direction that I am adressing....any 'objective' 
evidence anyone??
 What is the purpose of "wedging" a pinblock that is itself floating?, i.e. 
not mortised, glued, doweled...............
 What is the purpose of "wedging" a pinblock that is mortised to the 
stretcher, doweled to the sides and the top back plate flange is screwed to 
the stretcher ??
If there were pin block movement in this case would there not be separation 
of the mortise joint at stretcher-pinblock joint?
 Where did this measurement of a "business card" come from? Who set this 
standard? if less than a "business card" gap is there is that acceptable?  If 
so is a gap of half a business card going to cause problems with tuning 
stability? If not, why not?........... there still is not a solid flange fit 
is there?

 Again is there any 'objective' evidence in this regard?
