Adjusting Tiny Treble Bells (C#8 - C9)
(Treble 6th & 7th Octaves)
These little bells are really a trip to adjust! They use a newly designed yoke that requires a different approach.
First of all, the ball driver / allen wrench you use to tighten the cap screw that holds the handle on all your other bells won't fit bells above C8. You need a smaller allen wrench, which you might already have. Or, if you want a ball driver to fit these teeny bells, you can order one from Schulmerich on their website.
Second, to adjust the spring tension, it's a different approach than you use for lower bells. With the bells C8 and lower, you tighten a stop nut on the side opposite the where the clapper strike occurs that you're adjusting. The stop nut pushes down on the spring and restricts the travel of the clapper shaft. With the little bells, C#8 and up, you use a tiny screw driver and tighten the little screw ON THE SAME SIDE as the strike of the clapper you're adjusting. As you tighten the screw, it makes it jut out further under the rocker on that side and stops the clapper shaft from swinging as far. Loosening it (turning counter clockwise) retracts the point of the screw underneath, so the clapper can swing farther, make the bell easier (or too easy) to ring. So, you need a tiny screw driver, or a knife blade, to turn the screw that adjusts the clapper swing. Again, with these little bells C#8 and up, you're adjusting from the same side as the clapper strike, not the other side, as you do will all your other bells C8 and lower! If you want a tiny screw driver from Schulmerich for this purpose, you can get that on their website, too.
