It is quite unwise to lay cheek blocks, screws, or the slip rail on top of any finished part of the piano, especially on a high gloss finish such as that... Very high potential for making scratches. Put them on the floor!!! Any piano tech who showed that kind of disregard would most likely be shown the door by some of the customers whose pianos I maintain.
The explanation of the effect of tuning on the string is, unfortunately, incorrect. The *length* of the string is not affected by turning the pin, but the *tension on the string* is affected. Both would affect the pitch of the string but the length of the string in a piano does not change during tuning. It's a minor point but you mention it multiple times so it might be worth correcting.
All in all, a very informative video set! Thank you very much!
An improvement/addition would be to add another video in the series,which shows in detail how a key action works. What each part does and how it interacts in the complete sequence of events,while playing a note.
Ideally that would start with a radically simplified mechanism,and adding the different parts one by one to gradually improve on the total performance requirements.
I find it difficult to comprehend this by just looking at the complete action
My piano was made in March 1886, it's a baby grand and it does not come apart like that, my piano is so old and int great shape, but it does need new hammers. There's string bindings in bedded on them. =\
not to say keybed when talking of keyframe, wich is not is pine but in maple most of the time.
Not let the hammers push on the underside of the cavity when pulling out a grand action, enen temporarrly . The video is well sout. Interesting ideas, etc.
Thanks , indeed they are (probably) made by Renner (but Petrof une Imadegawa heads also actually).
I've seen some of that kind since then. Let me say those hammers are way too tall at 58 mm bore, (usually 48) and too little tail >> equilibrium is poor and wear is fast (much flexions on the shank) does not accept 3 years of Salsa play !!
high string plane or a choice to get that strong tone with undercentreing & and heavyness sensation.
Nice "hands on video" I was said taking out fast the action loke they do in factory was better for our back !
Key frame/keybed confusion, and the noise when brushing the hammers, you should may be say that that kind of lateral move of the hand on the heads is dangerous !
What is that instrument (are they ROnsen heads, or Abel ?)
oh no hes taking a part the piano, a grand one!!!

That would include playing a simple note and also playing a note as part of a trill e.g.
How to adjust these features,and what enables a note to be played rapily e.g..
:-)

I learned a few more things here...thanks!

The instrument is a Petrof therefore they are Renner hammer heads.
