I had searched high and low for more of his works, and then I picked up a copy of Woodworker's Journal, and there he was ... still teaching basics. Thanks WJ ever so much for publishing Ian's work. We need periodicals that cater to the amateur as well as the accomplished woodworker. And thanks, Ian. A lot. Ken Wood Brantford, Ontario WJ Responds: You might be interested to know that many experienced woodworkers have a similar reaction to Ian's articles. Router Bit Speeds I read your article "What's New in Router Bits" (Tool Preview, February 2002). At the end of the article there was a chart, which indicated what speed various diameter router bits would have to operate at in order to have a tip speed of 130 mph. It indicated that a 2'4" diameter bit running at 12,500 rpm would have a tip speed of 130 mph. I believe that number is incorrect and should be 93 mph. In order to operate at a tip speed of 130 mph, a 2lk" diameter bit would have to be going at 17,487 rpm. Jack Legato Salem, Connecticut WJ Responds: Good eyes — and good math. The correct rpm for the 2' -" diameter bit when it reaches 130 mph should have been printed as 17,500. Musical Correction The telephone number for the American School of Lutherie was incorrect in the February 2002 issue (Shop Talk, "Back to Shop Class"). The correct number is 707-431-9530. 2'A" Dia. Bit Tip Speed 22,000 rpm = 164 mph 17,500 rpm = 130 mph 14,000 rpm = 104 mph _^ Safety First: Learning how to operate power and hand tools is essential for developing safe woodworking practices.
