Have you ever tried to do something similar on a grand piano? ...if it were ever possible to do so
I have a customer who did it with pretty good result. He hung a paper under his grand piano and with crayon he drawed the outlines of the beams. So he had a paper with al the forms of the holes that needed to be filled. He gave them to a company that can cut the isolation precisely. He did 6cm thick polypress and on all sides 2mm extra so it fits firm in the holes.
Thank you very much!
How long is your table?
2.5 meters
@@CoenvanDongen WOW
How much time?
I'm not sure how much time this was but I estimate 3 days of work excluding drying times of steam and glue offcourse.
@@CoenvanDongen thank you so much for replying I'm starting in my country in Latin America I am learning by myself and I wonder if I am charging too little I wish I could know
@@CoenvanDongen I Love you work and I love the professional listen you put into everything
My opinion of that product it creat low sound effect of the unit.
When does a grand piano require a full restring?
well it look nice, I guess we can only assume it sounds better
Ellerine sağlık broo
Therapeutic to watch and listen. Thank you.
What is the tool that you use to pull the key bushing cloth through the slot in the key button at 2:47? Is it homemade or a standard technicians tool? I have never seen balance rail bushings done this way.
I bought it at Jahn Pianoteile in Germany. I know most piano suppliers have these. I don't know the name.
No soundboard shimming or recrowning?
Nope, That was not necessary. It ws a fairly modern D with no cracks.
@@CoenvanDongenthen why scrape and refinish the soundboard at all, then? Why not leave it alone?
@@pearlshark1 Cosmetic reasons, The original varnish had little cracks. The client wanted to have it look like new so I renewed the varnish.
@@CoenvanDongenthank you for your explanation. During the sanding process, is much spruce material removed from the board?
@@pearlshark1 Just enough to get al the old varnish out.
Excelente trabajo maestro saludos desde Morelia México
Beh sembrano mooolto competenti ed efficaci!
Um, the title says that this is an acoustical rebuild. But one of the most important things is to replace or at least test the tightness of the bridge pins. I saw the fellow filing the pins but I did not see anyone pull on them to test the tightness or replacing them.
I agree that it can be an important piece of a restoration. But in this case the pins were tight and they did not show any signs of false beats. They were happy there so I kept them there ;) The filing was just for shiny reasons.
Very Nice I would recommend editing your final frames/pictures as the hammer line does not show proper alignment. This may be confusing to some.
But then.. what is a proper alignment. Is it straight? Knowing action ratio has small changes and ask for different blow distances? Or would you adjust them in the key depth? So many questions haha. But seriously I always set the final blow distance in the piano itself by measuring the aftertouch in the key. I agree an uneven line might confuse some people ;)
Really cool video and interesting to watch!
Bedankt, heel interessant (ook de rest van je blogs)! Ik ben bezig met het uitzoeken van mijn eerste akoestische piano en maak mij een beetje zorgen hoe het qua geluidsvolume uit gaat pakken. Mocht het een probleem blijken te zijn dan is het fijn om te weten dat dit een oplossing is! Valt er nog iets te zeggen over het verschil in volume tussen bijv. een Kawai K-200 (114cm hoog) of een K-300 (122cm)? Hoger zal meer zijn, maar flink meer?
Ik vind het moeilijk om daar een uitspraak over te doen. Bij de meeste Kawai dealers zijn deze modellen samen te beluisteren en te vergelijken.
Thanks!
Great job, as usual. Thanks for sharing
Me thanks for it's AMAZING video there. IT (THE ACTON) must SUPER goes when your has do it smart job there! regards, Max,,,
Again....great work.
This is a bluthner! Old bluthner. I know... I have to copy that block 😪
Yes! Those are very difficult blocks to copy because of the double height. Good luck!
@@CoenvanDongen I've seen many, but other techs copied them in two separated layers, like the original, but in America there are multiple choice with block wooden materials and thickness. In Europe we are a little limited. Did you choose delignit? And for caps under brass plates? I appreciate your work of precision, I live in Italy and here there are very few expert technicians. Many turners, but not really "rebuilders"...
Coen, het blijft fantastisch wat je doet. Iedere dag dat ik speel/studeer op jouw Bechstein project geeft zoveel inspiratie en energie. Mooie werkplaats en werkblad trouwens.
@CoenvanDongen I have been following you. I hope China also has PTD training.
Wat een prachtig werk!
Great work and video!
Where do I learn how to do this and where do I get those tools?
Depends on your location. Find a local pianotechnician. He can probably tell you more about the possibilities in your area.
Mooi Coen! Complimenten ook voor het filmpje en de uitleg 👍🏻
GREAT 😉😉😉😉
Nice!! De link geeft een 404 trouwens
Dank voor de tip! Aangepast.
Very nice Coen! Thanks!

amazing work
Не могу понять, для чего эта скорость? Из всего видео, полезности 50%
Wow, love these videos of Piano repair!! I've got a Cable Conover "BB" from about 100 years ago I'm working on at the moment, might have to consider doing this job?
Interesting. Do you know how many decibel the reduction of sound pressure is? That would be interesting information. Thnx!
That is different with every piano and also... The result of the decibels reduction is relative to how much decibels the piano is. 3 dB less from 100dB is much more than 3dB from 99dB. Let's say it will reduce between 10 to 30% of the existing volume.
@@CoenvanDongen thanks! I will give it a try with my new Petrof P125. It goes fairly loud…..
@@jaycee_nl Those are great pianos, but yeah also load. Let me know how it turnes out!
Indeed it makes the Petrof noticable more quiet, but it is still quite loud for my apartment….
where do you live I might know you
All my details are on my website ;)
I have the harp of my old piano after it was damaged in a storm mounted on my wall and want to refinish it to bring it back to life. What primer and paint did you use?
You'll be fine with a few layers of spray putty and spray cans with antique gold.
FYI should of placed a flat steel cill
Looks gorgeous!
Amazing work! You do it all
Grossartig, bin gespannt! 🖖🎹
Gee the repair is amazing but requires a lot skill to do correctly.
Vet!! Lekker bezig. Thanks as always voor de shoutout <3
This is a knee jerk and stupid regulation on the part of the EU. Lead is ubiquitous, inexpensive, malleable, etc. I don't support this sort of lunacy.
GRANDE!!
Grazie maestro!😉
Did this piano get wet or something? Why was the soundboard finish so bad that it needed to be redone? How old was this D, I noticed you kept the dame pin block, i assume you used oversized pins? Looks great, nice job.
I think the piano got new strings in the past with the same pins. And I think the soundboard got a new lacquer back then. But the lacquer on top of the old lacquer. I think this is the reason of the crackish look. But I'm assuming. I'm not sure. The pins were 7,10 so a bigger pin was no problem here.
This is great, thank you so much for posting! I'm impressed at how nicely the dampers cleaned up at around the 21:20 mark. What did you use to clean/polish them?
It's simple polish for polyester. The brand is Zweihorn
quick question, why if they are cheap and easy to remove you didnt replace the plate pins, the gold paint doesn't look as good as a new shiny pin, I have seen it in many restorations, same old plate pins paint in gold, sometimes the paint come off
You're completely right. I've changed this and now I use rubber tubes on the platepins while painting or I change them for shiny ones.
Dear colleague, please tell, how you control hammer tilting of angled bored hammerheads in a bass and treble sections by using this jig. And one more question, how long apromexitely does it takes to install whole set of hammers with the jig. Thank you in advance, sorry if my questions disappeared you.
It takes me about 4 hours with rolling the shanks and cutting afterwards. I don't understand your first question.
