<html> <body> Hi Phil.              It will work like a dream. I reset the CNC machine in the plant late last fall. So you should be seeing the improved product on dealers floors now. You ream from the  top  through the key mortice. The reamer is not tapered, and can be obtained from Pianotech or Jurgen. Keep your finger firmly on the bottom of the BR hole to block the reamer from cutting too much material.  The reamer has a 4mm round tip, and two little blades that will cut away material from the top of the BR hole. Can some one cut and paste a pic from Jurgens site?  I am not that computer savvy.

Thank you Phil Mosley</blockquote></body> </html>
