Yesterday, I was working on a friend's YAS-475. He was complaining about increased resistance and decreased response. Sure enough, the timing on his lower stack keys were off causing some significant leaks. The issue was simple to fix as it just required a few strategic turns on his lower stack adjustment screws. The process may have taken 2 minutes. It then dawned on me that a similar repair on my SA80 would take about 10 times that, as there are no lower stack adjustment screws on that horn. Cutting, shaping, and gluing corks that are of proper height takes time. So that got me wondering. Has anyone ever fabricated a stack key adjustment mechanism for a horn that lacked this feature? Has anyone ever drilled into the rods in order to duplicate this feature? And mind you, I'm not looking to do this to my own horn as I'm lacking the necessary tools and knowledge of advanced metal work to even attempt this. This is purely just an inquiry.
