Great work. I picked up a few tricks by watching! (Paper clip to help align front rail pins, tape on strings to give clean line for damper installation). Where did you get that hammer hanging jig? Very cool
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.
Since the hammer shanks and butts are to be replaced too, the shanks have to be glued and pressed to the hammer first and they should be tight. Then the shanks with hammers are cut into the right length and fit to the hammerbutts. And the adjust of hammer spacing and clearance to the adjacent hammers when the it is moving towards the strings, the angle and the catchers’ alignment are made by filling the bottom end of the shanks before gluing them to the hammerbutts. It is a standard practice in piano making for many years. And these procedures provide the best stability and longevity to the action. The keys are 1. Glue joints has to be tight whenever possible 2. There should be sufficient clearance when the parts are at rest or moving. 3. The spacing or the parts has to be even.
I’m not a great player myself. I will let a colleague play something in my next video. I agree that playing the instrument after rebuilding is a better closure for a video.
Pretty cool to see the action rebuild practically from scratch! How many hours do you pound the keys, typically? I use that same WNG pounder when I do a Grandwork regulation. It’s great!
Een Vlaams gezegde begint met de openingsregel: “eert wat oud is”. Coen begrijpt deze openingsregel volkomen. Als geen ander is hij in staat te herkennen of een oud instrument kans maakt op een nieuw tweede leven. Als geen ander weet hij met z’n liefde voor vakmanschap de klank uit hout, vilt, snaren en techniek nieuw leven in te blazen en tot recht te laten komen. Helemaal onvoorstelbaar is de gedachte dat je daarna op een instrument speelt dat waarschijnlijk al gemaakt is terwijl je zelf nog niet geboren was. Dat dit instrument er dankzij - zijn deskundigheid - er later nog is, terwijl je er zelf al niet meer bent!! Als pianist ben je muzikaal verbonden met een stuk historie en reist er samen mee de toekomst in. Wat die reis gaat brengen weet niemand maar dat de eigenaar heel veel plezier aan het instrument gaat beleven is zeker. Nice work!!
Bellissimo e bravissimo
Nice video's Coen, im a piano technician in Australia just wondering where you purchased the the soundboard cutting tool for shims?
There is a similar one at Jahn Pianoteile Germany from "Einhell" This is an old version of it.
Thanks checked it out. It's 1950 euro. Bit un affordable unfortunately.
@@paulknight6508 Yeah, I agree. I got lucky to buy it secondhand from a colleague.

Thank you, I made the jig after seeing the video of www.youtube.com/@Klavieratelier He has made an upgrade using magnets recently.

I bought it at Jahn Pianoteile in Germany. I know most piano suppliers have these. I don't know the name.

Yes, I have been doing it like that for years. I wanted to try it with the gluing jig this time since there was no option to get the piano in my shop.
beautiful job, are you going to play it for us?🎂

Yes, i was so disappointed not to hear the piano after all that amazing work
Great job.

In this case I did 2 hours
GOOD JOB!
Grazie mille!!

Ik gloei!
Why was it not refinished?
The owner didn't want the outside to be refinished.
@@CoenvanDongen great job!
