I'll follow myself up on this one. I spoke with Ruth McCall last week and found out that because the tool isn't built to last forever (gasp!), it requires parts replacement after considerable use. Specifically, there are *four* bearings (two for each pulley) that can wear out in addition to the drive pulley which is under tension all of the time. Ruth sells the parts ($6.50 per bearing and $26.50 for the drive pulley). I figured there must be some explanation for wasting so many belts prematurely -- especially lately. There was enough play in the drive pulley end that it was causing the belt to ride up and off, fraying the edges as it slowly worked its way off. I'm hoping the probelm will be solved with the replacement parts. Ron Torrella Assistant Piano Technician School of Music University of Michigan
