Crow's Foot Adjustment

Author: Bill_D

I'm a beginner at clarinet playing and clarinet repair, and I don't know the proper names of some of the relevant clarinet parts.

I have a Yamaha YCL-250. Low E and F are satisfactory. I have to press harder than what I consider normal for Clarion C, and much too hard for Clarion B. When I get Clarion C working okay by bending the pad cup, Clarion B gets worse and vice versa. I seem to be going back and forth in an seemingly endless loop.

The pad cup seems to require a lot of force to bend. QUESTION: Is this a Yamaha YCL-250 characteristic? I apply a little force to bend the pad cup and nothing, then more and more force until it seems like the pad cup bends too much.

I checked the seating of the pad closest to the crow foot with a cigarette paper feeler gauge. It is tight where the pad cup connects to the linkage arm, and on the sides. The side of the pad opposite the linkage has only slight resistance with "normal" pressing of the key and can be closed completely with harder pressing. QUESTION: Does this mean that the pad needs to be re-seated or does bending the pad cup affect the side away from the linkage more? I don't want to heat the pad cup and float the pad to position if unnecessary as this might make things worse based on my limited experience (I have installed flute pads using paper shims). The pad furthest from the crow foot seems to have the same issue, i.e., the side of the pad opposite the linkage is very slightly open.
