Upright action, sticks on slow release? #2927062 12/26/19 05:43 PM

I have a couple of keys on my piano that if released slowly will sometimes not fully release. By that, I mean the key remains partially depressed even though I'm no longer touching it. If you then attempt to play the key a second time it reacts the same as when you fail to fully release a key before repeating a note (jack jams?).

This is currently occuring whilst I'm playing a number of pieces on the A#2 and A#4 keys. It seems to occur when I'm playing softer/slower passages and have released the key slowly. I can see a visual difference in the "height" of the two keys when they're "stuck". They remain partially depressed without touching them.

I've been through a number of the other keys to release them as slow, however in all cases when I've nearly fully released the key I can hear the action free up ready for playing again. A#2 and A#4 on the other hand, will regularly stick as I slowly release them.

Any idea why these two keys may be jamming? I assume this is abnormal as the other keys I checked do not react in the same way?

Be helpful to know if this is an upright or grand?
Either way, it sounds like your action needs to be regulated... When was the last time you had work done to it, other than tuning I mean?


If this is an upright (vertical)-- it probably needs a little lost-motion introduced.
You might try lifting the hammer-rail just slightly (just a hair off the resting point)- while you play those particular notes- see if the offenders repeat properly then... If so, you could place a few thin strips of felt under each of the hammer rail's resting points- between the bottom of the rail and the action bracket (there should already be some little block felts there- you want to just increase the amount of felt there about 1/32 to 1/16")--- thus raising the hammer rail slightly. This should be enough to solve jack hang-ups on those notes. The action will feel different though, since you introduce lost-motion between the keys and the hammers.

But, again, either way (grand or upright)- it appears you need a tech to do some work on it, get the piano back to proper playing spec's. It's called an "action regulation", or even just a partial regulation would help.

It's a new upright (K300) so has yet to be tuned or have any work done other than the final setup that was done at the factory prior to shipping. I received it during November and it's due a first tuning. I'll mention it to the store and check if this could be looked into at the same time.

It may just be tight key bushings, as it's a new piano.

Key bushings was my first thought as well. And/or excessively tight BR holes on those keys.

Agreed with others-- being a new piano--- key bushings are most likely

Note it and tell the technician when it is tuned. It should be covered under warranty.

Thanks for the replies everyone. I'll ensure it's mentioned when the tuning is booked.

Had a tuning today and the keys were looked at. I thought at first that the issue was resolved but after further playing tonight the issue persists on one of the keys.

Before I phone the technician to ask if he can have another look at the key, could someone confirm that with an upright, if you release a key almost fully but not quite, then release it fully, the key should be playable and the jack not jam? When I release in that way, or release the key in one motion but quite slowly, the key doesn't repeat.

To be a little clearer about what I mean, in this image the part that's labelled "back check".

If you play a key, then release the key so that the back check is almost but not quite (perhaps a few mm short) of fully back to its resting position, pause then release the remainder of the way (the back check returns fully to its rest position). The key is not playable.

I'm not sure if it's how I'm releasing the key that's the issue, or if the key should still be repeatable regardless of how slowly I release it or whether I have a slight pause during release before fully releasing. None of the other keys appear to be doing this though.

tl;dr no matter how slowly I release a key, if I have completely let go of the key, should the action ensure it's always playable again?

How you are releasing the key is NOT the issue. Could be sluggish jack flange. The action should be playable again no matter how slowly you release a key.

Thanks for the reply. Technician has resolved the issue. I'm not sure exactly which part it was, but I think it was jack related and a little bit of extra friction compared to other keys causing it to stick when released slowly.
