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.
