Hey all, so I've been working on a 1950's Pan American Alto and I need some help. This is my first time working on a horn so I am still learning.
I've replaced all of the springs which was a pretty simple task; however, pad installation is giving me some trouble.
I used shellac to put the pads in, and all of them fit just fine. My problem is, even though I have seated the pads and they all have good looking rings on them, I still get leaks.
What else do I need to do? I understand that the tone holes need to be level and they are. I just can't seem to get these pads to seal?! I tried music medic's technique of "fluffing" the pads which is where you heat the pad cup then pull the pad down with a pad prick in the areas with a leak. This seems kind of a harsh treatment to the pads in my opinion. I am seriously desperate for help and have no idea what to do. No matter what other forums I've read, nothing seems to help, so I'm hoping a very experienced technician on here can help!
This has been driving me crazy for days!
