just found this by chance. I love the slowed down photos of wooden shanks. They bend! This means that they are stroking the string as well as striking. I would expect on the face of it, that this would mean less sound and maybe a softer tone. Am I right? A very interesting video.
Well done, Chris! Dave Hughes, RPT
Please don't make any more price increases on the parts please. Thank you !
Del is like a god in the piano tech world. I do wish the physics in his submitted PTG magazine articles would be omitted since most of us never had the subject. Thank God we have people like him to rethink the piano wheel, so to speak.
I wish they supported actions they made 100 years ago...
Can I come to your store with the old flanges and shanks and get help on which set that I need to purchase? Thanks.
It was only a matter of time before a device for this task went into production. Those of us out here have fabricated various mechanisms to do this work, but I think this machine is wonderful and way cool. Definitely on my wish list now. Great job WNG engineers !!
If stiff hammer shanks are superior why did market leaders like Pleyel continue to use flexible cedar shanks well into the early 1900's? Hint: the sound
Massimiliano DI MARIO why did they stop then?
We fit WNG actions as standard to all our pianos. This action is part of the piano revolution that is happening right now. We find that the large majority customers, when blind tested, feel that a WNG action is far more responsive than a standard wooden action. If you've never tried one, make sure you do!
Metal rail and perfectly molded pressed flanges, one has to wonder why so much travel paper is needed, just saying............
Great instructive video. When in doudt read the instructions!
I'm seeing a lot of flex in the joint between the shank and the hammer.
The comparison of the performance of the two wooden hammer shanks is unfair: the first one demonstrated, the "ideal" wooden shank, is a full bodied hexagonal unit intended for the bass or tenor section of the grand piano. The second one demonstrated, the "inferior" shank, is an intentionally radically thinned shank intended for the high treble section of the grand piano, to reduce mass for the purposes of improved tone (a less woody sound) and quicker repetition speed. It naturally will have more flex. The video implies the two shanks are identical, to support the position that wooden shanks are inconsistent and thus inferior to a carbon fiber shank. This could be misleading to some viewers of this video.
If I'm not mistaken then, the actual situation is different from what they represent but it still isn't 'good' - it implies that traditional pianos have systematic inconsistencies in action between bass and treble.
