 I mix the epoxy up 

according to the instructionsand add the microlight filler until it is a 
little thinner than peanut butter (creamy!!).  Spread the mixture on the narrow 
edge of the block and put in place.  Clamp it to be sure it stays where you want 
it to be and leave it sit overnight.  Wipe off any gross amounts of squeeze 
out.

 The next day - remove the clamps and teh block come right off.  The Saran 
Wrap will peel off effortlessly.  Any epoxy that worked around to the pinfield 
can easily be sanded off. >>

Greetings, 
     If there is expoxy working into the pinfield, then the block is not well 
fitted to the underside of the pinfield.  I think it is equally important 
that the block be fitted to not only the flange, but also to the underside of the 
block.  I have seen an extremely well done flange/block fit go out the window 
when the screws were tightened.  This is because the block has been "warped" 
to the underside of the pinfield and the distortion alters the flange fit.  
    If using epoxy to fit a flange, I suggest that the block be held in place 
with the screws  instead of clamps, but before any of this, make sure the 
block fits under the pinfield as well as the flange.  A poorly fitted block is 
responsible for 1 cracked plate in a Steinway B that I know of.
