Agraff Torque

[A440A@aol.com]

<<  These agraffes have broken; and, their posts will not

come out by any means thus far tried.  Professional machinists whom I have

consulted can't budge them either.  Now what? >>

Greetings, 
      You will need to drill the posts out to almost the id of the threads, 
This has always loosened them up for me, but be carefull not to drill the 
plate.  If the remnants still won't budge, the you can run a tap of the appro. size 
in there and cut out the remaining brass.  It helps to make sure the first 
thread on the plate is exposed.  Do this with the needle bit in a Dremel.
