Instructive Little Puzzler

[Sid Blum]

Backcheck leather unglued?

>Problem:  Acrosonic with a key that just occasionally sticks after a 
>hardish blow. And when it sticks, it really sticks.
>
>Diagnostics:  Keystick NOT sticking. NO foreign objects or parts 
>interference. Jack and jack spring working just swell, thank you. 
>NOT a pinning problem with any flange. Damper working correctly, 
>spoon NOT corroded and NOT digging into the felt. Hammer and butt in 
>good condition and traveling correctly. Lost motion, letoff, and 
>aftertouch (on a spinet?) nicely regulated, after some adjustments 
>by yours truly.
>
>Hint: Had to remove the @*&#$% action and practically use my xray 
>vision to spot the problem. Actual fix took about 15 seconds and 
>required a tiny drop of PVC-E glue.
