Hi all,
One of my sophomores has a Yamaha YCL-221 bass clarinet, and the craziest thing happens with it. The register key is always extremely delayed or sometimes does not lift at all when the mechanism is pressed. I have looked at it and it looks perfectly fine; the pad is not sticky and all rods and springs are screwed in and are in working order. The really crazy thing is that one of my juniors has the same model bass clarinet and supposedly the same thing happens to hers as well. In fact, we have five of this same exact model (three are students', two are "borrowed" from a nearby middle school) and I'm concerned that this is some sort of manufacturing problem. Does anyone know if I'm just missing some simple key oil fix or if this is a bigger problem?

Check all the parts of the mechanism mounted between pillars have some end play in them as plastic bodied instruments will expand and contract causing key barrels (hollow and mounted on a rod screw) or key rods (solid and mounted between point screws) that are well fitted (with very little to no end play) to act sluggish or bind up when cold.
This can be resolved by having the affected key barrels or rods fraised back with the specialist cutting tool to give a nice smooth and square end (as opposed to being filed or sanded) to create some end play relative to their lengths (longer key barrels/rods need more end play than short ones).
