Hey guys... I have a small question. You know the Bb - G#/Ab adjuster screws? Well kids ALWASY find a way to get the corks under those to fall off. Now to replace it, I just cut a circle in a sheet of cork (with the appropriate thickness) and glue it on there. That works fine. But when you buy some of these horns brand new, instead of cork, they have small short tubes of rubber or cork that fits up in there perfectly. I really hope I'm describing this well. Anyway, i can't find a tube of cork or rubber that short or thin ANYWHERE!! And when you order from Allied, Selmer, or Yamaha, all that you can get is the entire screw replaced. You can't buy just the rubber or the cork. And for certain horns like cheap conns all the way to Mark VIs I'd like to have the right stuff. I certainly can keep doing what I've been doing and just glue cork onto the screws, but do any of you guys know where to maybe get the replacement rubber/cork that will fit up into the screw the proper way? Hmmm....
