Hey Howard, remember me? As I do an entire set I can never get them all perfectly consistent. So, I carry a $40 large/complete set (from Harbor Freight, cheap Korean set) of drill bits with me, (lettered, #, etc) and a micrometer. I mic the key pin and us a drill bit a couple/few thousands on an inch larger than the pin. I chuck the drill bit in a T handle UPSIDE DOWN or CHUCK SIDE OUT/CUTTING END IN THE CHUCK of T handle, and just go through the set from the bottom. I'm careful about entering straight. I can do a set in just maybe 3-5 minutes and know that they are exactly the same for my purpose. In Louisiana's humidity, I do this on almost every action I regulate or do any substantial work on. I've never had anyone tell me why this is a bad idea....Maybe now?

Rosen Sent: Monday, January 01, 2001 12:08 PM To: Pianotech Subject: "pulley" keys Hello Friends, I would like to air a concern of mine and elicit some response. Despite my efforts to carefully ease key balance holes from east to west only, and to perform this repair minimally to avoid pulley keys, I often get a very slight pulley action after sufficiently easing the key. It seems that I cannot get the desired easing (such that the key drops of its own weight after lifting it about a half inch or so) without getting a slight pulley affect. Does it sound as though this is to be expected? Or... am I not being careful enough? Yes, I am using the appropriate tool, entering it from the top of the key, and then turning it 90 degrees before easing. I am very careful not to ease top and bottom but only left and right. What are your thoughts?
