Really cool video and interesting to watch!

Absolutely amazing skill 🙌🙌❤ Always love to learn piano repair work but unfortunately in my country there’s no any resource. Great job enjoy the video and the Haina Rani’s background music is perfect suitable. ❤

Wat een schitterend ambachtelijk werk. Petje af.

Prachtige video, en vakwerk. Petje af!

Coen - This is excellent: not just turning the 'cricket bats' for you!

Great job! I’m about to do the same on a 1963 Steinway Model 45. Abel hammers, too.

Music: Hania Rani👍🇵🇱

Prachtig Coen 👌

Great Video. I'm really enjoying these videos. As a pianist, it's great to see all the work my technician puts in to maintain my instrument. What do you use to clean/polish the white keys?

Thank you. I used Innotec Foam glass clean. It's a product that is normally used in the car industrie.

That's a Hoffmann of the 1980s built by the " Euterpe -Group (together with Euterpe and Feurich). Much better pianos than the Hoffmann- pianos built later under the guidance of the Bechstein- Group, first built in the Czech Republic, later (from ca. 2002) in Indonesia.

Some of the Czech ones are nice to. Just like Petrof, they accidently made some very good ones ;)

I was at the factory in Gunzenhausen/Langlau in 1987. Saw ever phase of production there. All first rate stuff

The staffs who glued the hammers in the Langlau/Gunzenhausen factory did not assume hammers to be glued at 90 deg but looking for the maximum clearance to the their neighbours. And the glue joint between the hammers and shanks was much tighter.

useful video!

Is missing knag in last key (05:04) part of weight balance of key, or not? ;-)

What is the music being played? It is hauntingly beautiful to hear while you work. ♥

Most of it is Hania Rani. I like it a lot.

Great video and great music, looks like quality work! Is that steam you used to weaken the key bushings? There's no chance that would warp the key slightly? Or I guess you would have to leave it there a long time for that...

Thank you. The steam is very local so it’s save for warping.

Hello sir, kindly suggest good quality complete piano maintenance tool kit. I am a carpenter & I did the carpentry and mechanical engineering work a lot so I will be able to do this as I understand each and everything very well. As I said unfortunately I don’t have resources of learning here so I will start learning by my self your videos will definitely helpful to me. Also suggest me the oil and other thing to lubricate the moving parts in action. It would be great help to me. Thank you so much for sharing your skill. 🙏
