    Thank you for this video. Its very helpfull demonstration. I would love to learn more about the process of fixing key weight. Im piano trained technician from central/eastern europe, studied at Petrof Factory, but there is so much more to learn about our job. Ive been doing my job for over 10 years, but i always feel like i dont know and understand enough!

    Thank you for explaining inertia so well by showing your key at the beginning. Wonderfully explained, thank you so much!

    I‘ve seen many of your videos and I am an admirer of your work, really! One thing : You can change the knuckle position without changing the capstan position. Then you just have to install the whole action more forward or backward. Of course you need shorter or longer hammer shanks then, according to the action position change. One can also change the capstan position without changing the knuckle position. Then the has to be moved forward resp. backward, too. The length of the hammer shanks also has a big influence to the touchweight. Especially with heavy hammer heads. Thanks again for your fantastic videos!

    Will putting hammers closer to strings make subjective feeling that keys are sligthly easier? I am wondering if there is a shorter way to string, could pianist play fast passages with less power to produce sound? Sorry on bad english

    Hi, love your work, moving capstan back changes key ratio. So they have increased distance from balance pin to capstan, this moves away from 2:1 key ratio. The action ratio/ geometry is all mostly same modern actions. By moving what they did requires more lead to acheive required downweight, then affects upweight badly. Result piano wont play properly

    Your device, while clever, is only demonstrating changes in the static downward force on the capstan. That has nothing to do with inertia. Inertia is created as the mass at the back of the key begins to move. The faster the mass is moving, the more inertia is created to work against the player. Moving the capstan in any direction will not change this. You must remove mass from the back of the key, and then you can effectively remove some of the front lead counterweights as well. This reduces the inertia significantly, and makes the piano much more controllable and pleasurable to play. I have a system I created to calculate and perform this process and have implemented it successfully on many instruments that were otherwise unplayable, with great success.

      Thank you for this. Almost all technicians have no idea about inertia. All they know is static down weight.

    I see you chose renner action in this case. Was there anything you didn’t like about WNG ?

    The speed of the hammer decreases this way too so the dynamics change!
