Bill, Paul, I have mentioned this before on the list but it works so well for 
me it bears mentioning again.  I am not sure who to give credit for the idea 
but you can make a feeler gauge out of balance rail punchings. Two 3's, two 
5's, two 7's and so on, glue two 3's together (only overlapping 1/2) then 
glue two 5's and glue them to the 3's (same 1/2 overlap) continue to thickest 
punchings.  I then glue the row to a popsicle stick and there is your feeler 
gauge.  
I looks like this OOOOOOO======.  If need be I can send a picture.
                       
Slide your gauge between a straight edge and the key and if it fits where the 
two 5's are overlapped but not where the 5 and 7 are overlapping you will use 
a 5 !

I like to level with the stack on in the piano, using tape along the front of 
the keyframe to mark the size punching I need.  I also compress my punchings 
with a drilled dowel in the same manner that Joe Garrett described in this 
months Journals TT&T section.

I find this method fast and accurate.
