[pianotech] Regulation Question

[Tom Driscoll]

Backcheck rubbing on the tail on the way up or jack too forward(pianist side ) in relation to the knuckle. 
If you look at the action with the fall out the jack will tell the story or apply pressure to the top of the hammer whilst you depress the key (action out)and the check may rub on the tail.
Check the action rail screws to see if they are loose. I had an estonia where the rails were not shimmed to stabilize location and when the screws got loose ,geometry shifted and all sorts of things can go wrong,

          I was working on a Baldwin SF10 today.  On several of the keys, I could play the note if I put my finger on the key first, then lifted my hand as I played the note.  I could play forte or louder this way.  But if I struck the key with my finger, the hammer would not go up.

          Any ideas?

          If yes, what could be the issue?

  Hi Matthew,

  Instances like this is where you as a technician must learn to analyze what is happening and why. You are not working in a vacuum situation in this instance. Everything you need to figure out the problem is right in front of you.

  You state that several of the keys have this problem, which means that the preponderance of the keys don't. You, as the tech on site, should be able to do a comparative analisis of why, between those that function properly and those that don't.

  Those of us who came up prior to the internet and cellphones learned to do this, you should too!

  I'm not saying you shouldn't ask questions, I'm saying you should attempt to figure it out for yourself, this is what makes you a true technician. If you simply can't or the result was unsatisfactory or satisfactory then post with the problem and what you did to see if there are other ways to do it or how to do it.

  Mike
