To those of you who saw Chris' demonstration and are ready to try it.....What would be the advantage to using an oscillating sander? Does it work that much faster? jeannie Jeannie Grassi, RPT Assistant Editor, Piano Technicians Journal <mailto:jcgrassi@earthlink.net> mailto:jcgrassi@earthlink.net _____ From: pianotech-bounces@ptg.org [mailto:pianotech-bounces@ptg.org] On Behalf Of Jon Page Sent: Saturday, December 03, 2005 9:29 AM To: pianotech@ptg.org Subject: Spindle sander >My only concern would be that the extra motion from the oscillations would >cause the hammer(s) to move too much in the process.

How are they held? >jeannie The shanks are off the rail during the reconditioning process to be repinned, filed, tapered, tail arc'd and weight graduated. The rail sandpaper is replaced from a roll available from Klingspor; www.woodworkingshop.com; 220 grit for flat rails and fine emery cloth for tubular action rails. I usually file at the drill press with a 1' drum sander. I have two elevated surfaces to place the hammer for filing, one angled for previously tapered hammers and one for hammers with parallel sides. They're about 2" high to accommodate the rake of the bore. A reshaping takes about 45 minutes, even for really flat hammers. Sometimes a second filing with a fine paper drum puts a nice finish on them. Hammers which are not too grooved can be reshaped with the fine drum. I was just wondering if the oscillation of the spindle would cause ragged edges. -- Regards, Jon Page ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
