Hello,Listers! Here is a little trick in fitting agraffes.Instead of using expansive machinist mill to remove exess of material from the "seat" of the agraffe simply do that: 1]Take hammers filing wooden paddle with sandpaper on it: 2]Drill 1/8 inch hole: in it 3]drop the agraffe and gently make 1/2 clockwise+1/2 turn counterclockwise back and forth a few times You will be able to see some brass microscopic shavings falling off.. that's enough to reduce the brass from the seating surface. 4]re-install agraffe in question and re-alighn .It woyks! Good Luck!
