      The most popular tools
           to come along in years-
               Only because they work!

     These tools are all on page 144 in your 2001 green catalog

      Z60-27 Big Disc used with wider Z60-28 Roller on a Sousa Bell

        
        Like driving a bus, stand in line with the center and hold Up with fingers. 

      Z60-25 Small disc used with Z60-29 Tapered roller on a Trumpet

     Note the Z60-29"s tapered shape provides a "Safety Zone" in side the bell.
         
      Notice the position of the operator.       It's easier to keep centered.
      When using the Power Discs we recommend standing directly in center
      with the bell as opposed to off to the side of it as with the shoe method.

      Z60-28 Wide roller used with the Medium Z60-26 disc on a French Horn


        
               Notice the Safety Zone created by the Z60-28's EXTRA WIDTH
        

      Z60-24 Sax disc used with Z60-30  Convex roller on a Saxaphone


                 
                 Move slowly due to small radii and out of balance weighting.
                 You have a lot of power and the sax is out of balance, careful!
     You CAN restore the contour of the bell if you watch what is going on.  There will be three distinct "ghost" areas on the convex roller after some use; alto, tenor and baritone.
