was loc-tite agraffes now plate positioning system

[Bob Hull]

I knew that and for some reason forgot.  So, it would be good
to have 2 sets of agraffes on hand.   The last couple of sets I cleaned and reamed the old ones which went back to their original positions. This piano is getting the new.   

I'm wanting to use the plate height positioning system you described and can't find my notes from our conversation.  I have the socket set screws and the acorn nut for the top and didn't remember what you used for a nut or washer under the plate for the plate to rest on.   How about a jam nut that has a low profile and loc-tite (red) it in place.  Only thing is I may not have enough room under the plate and would perhaps have to drill out the board there some.
Ok. I owe you another piano.
Thanks,
Bob

Whoa Bob! Concept alert!!! You're making it way too tough. 
Forget shims unless you want to change the agraffe height. 
Start with maybe 10% more agraffes than you need for the job. 
Spin one in, and see if it snugs up around 45° short of where 
you need it. You'll develop your own tolerance for this after 
doing a set or two. If it doesn't line up where you want it, 
spin it out and back in the next available hole. When you find 
a home for that one, grab the next agraffe off the pile and 
start at the first available hole doing the same routine. 
You'll find that there's usually an agraffe for every hole 
that fits within your tolerance, without modifying or adding 
*anything*. Make a tool to quickly spin the things in and out, 
and you'll find you can replace a set in well under an hour 
with minimal angst. That's my tool below. Actually, it's 
pictured with the wrong handle. The right handle lines up with 
the slot so I can tell the agraffe position without removing 
the tool and looking.
