A better way to sand.
At the last national NAPBIRT (National Association of Professional Band Instrument Repair Technicians) convention in Tuscon, Matt Scott from MusicMedic.com gave a clinic and MusicMedic.com exhibited tools and supplies. Although these activities were great, the best part of the convention for us was attending other technician's clinics. One never knows where the next good idea will come from at these clinics.
While we were attending a particularly great clinic given by Dale Barton we picked up this tip. Months later we gave it a try and it's a great little time saver I thought I should share with you.
It's this simple: Put packing tape on the back of the sandpaper you use in the repair shop. There are two reasons to do this. First, the tape makes the sandpaper much stronger so it won't tear when you are ragging or sanding under key feet. Second, the tape is much less abrasive than the back of the sandpaper, and doesn't scratch the body of an instrument when you are sanding key corks. This tip has saved us a good deal of frustration, not to mention sandpaper.
Give it a try!
