A #7 drill bit is 0.2010" in diameter, huge in comparison to the agraffe hole, so I presume you do not mean an actual #7 drill. Could you explain? ( And - how modified?) Bill Simon Phoenix >> Hello Bill, et al, The key word here is: CENTER drill. This is special bit used on metal lathes to make an indentation in the end of your stock so it can be placed in one of the centers (for lack of a better term, "clamp). This can either be the drive center or the end center. The easiest way to describe the modification is to look closely at the inner contour of the hole/face in the agraffe. Take the agraffe to your favorite machinist, and have him/her grind your #7 CENTER drill to the same contour. I hope this helps. If you all can recieve .jpg or .bmp pictures, I could post a drawing of the modification. Anyone interested? Brian De Tar Portland, OR BDeTar@aol.com "NO OBSTACLES...ONLY OPPORTUNITIES!!"
