Hi all,
After playing my Hohner Piano 26 and 27 hard, I am finding that a couple of black keys are occasionally binding up. They are staying stuck in the down position, causing the note to sound all the time. I can pull the key up, but can feel the resistance, and it just gets stuck again if I press it down. If I play around with the key (tap it, wiggle it, or sometimes chant a incantation and let the melodica sit), it will start working again. I took one apart, and at least this time, could not figure out what is causing the problem.
I am sure I can figure that out, though ideas are welcome.
My real question is this. As I slowly press the working keys on these melodicas, some of them are clearly rubbing on adjacent keys, or the pivot point, or the valve shaft (if that is the right name), as I can hear squeaking or scratching as the keys moves. Is there an some sort of instrument oil (trumpet valve), food-grade oil, or other type of light lubricant that I might use to smooth out the key action or perhaps prevent sticking key/valve problems?
Has anyone tried this? Am I asking for trouble in terms of collecting dirt, gumming up the reeds, poisoning myself?
If so,
