I am in awe of this painstaking craftsmanship. The contrast between the forceful manual labor and the ethereal musical background of the completed organ is unforgettable.
Profound marriage of craftsmanship of organ pipemaking set to Bach's BWV 659.
I really like the way at 1:51 he just knows where to mark the cuttings for the pipe foot without rulers. Craftmanship in action, they make it look so easy, which of course it isn't and takes decades of training.
Ahrend make superb organs in the North German style, perfect for Bach. Who knew their organs (some of them huge) were built out of such a comparatively modest workshop, staffed by master organ builders?
Look closely. He's using a basic jig with converging lines marked out to indicate a given mouth proportion for a pipe body of any diameter.
Very good cutting in the end, showing the immense amount of work to build a full instrument.
Yes, and that's just the pipework!
A slightly different soldering technique (rubbing the iron back and forth) than I have seen before.
Thanks for the interesting upload.
Its welding, not soldering, since the bulk material is being melted and mingling.
dear master Hinrich Manssen, you are extremelly experienced man
Beautiful work of a true craftsman.
Fantastyczny film pokazujący powstawanie piszczałki.
Muchísimas gracias por esta completa demostración artesanal. Los órganos Ahrend tienen su indiscutible sello de calidad.
Het boek, de dvd en 5 cd's zijn uit. Echt geweldig zo'n document. De meeste muziek wordt gespeeld door Sietze de Vries.
Man, this material looks so easy to work with compared to stuff I've used, cuts like butter
That is just fantastic! What an art!
Superb.
Thank you very much for this video.
Sehr schöner Film! Danke für's Posten! Ich hatte schon die Ehre bei einer Führung durch diese Werkstatt dabei zu sein :-)
Incredible.
Very informative. Thank you!
The music is Bach's BWV 659 Nun Komm Der Heiden Heiland
Beeindruckend kongenial (Komposition, Orgel, Interpret): BWV 659 mit 32' Praestant im Pedal: so klingt für mich der Gang nach Golgatha im Advent! Dazu das beseelte Spiel...
Wow never knew it was that labor intensive!! Now I know why organs arent cheap!!
Indeed. This is just making a single pipe. There is a following process where the pipe is voiced, where its mouth is cut-up, toe-hole adjusted, languid (tongue) is adjusted up and down, and the upper lip is moved back and forth so that it is transformed from a tugboat whistle into a musical instrument of a definite timbre, grouped with its partners within a rank (set of pipes within a 'stop'), and appropriately married to its venue. This process has to be repeated literally hundreds of times. One pipe for every note of a keyboard (61 for the hands and 32 for the feet), multiplied by the number of ranks of the organ. Even humble and small organs have 800 pipes.
Mooie film 5*
Nun komm der Heiden Heiland
How can i make that 😊
Ich war schon mal hier ;-)
Da sitzt jeder Handgriff... ab 3:25 der "Zinnschrei". Bei üblichen Trommelhobelmaschinen werden die Metallplatten bereits vor der eigentlichen Verarbeitung gestaucht und gestreckt, hier werden die Platten schonend behandelt, das erhält von vornherein eine höhere Stabilität der Pfeifen. Das Video "atmet" jahrzehntelange Auseinandersetzung und Erfahrung mit der Pfeifenmacherei.
WOW I never considered this casting is done by hand. Is that pewter? I really love the precision work. Those people are very skilled.
Its solder basically, lead/tin, very low melting point, but some additives for strength (antimony, as used in typemetal too). Pewter is basically tin, this is basically lead. The high density affects the acoustics of the pipe I suspect.
When a builder makes a 32' Principal, as at Hamburg, how do they roll this metal? It must be much thicker, to endure the enormous weight of such large pipes. How do they get the metal thick enough to withstand days/moths/years of time standing up there, without falling down?
usually made from zinc, not the lead/tin mix that you see in the video.
shop shop Not necessarily. Plenty of organs have 32' facades of non zinc.
Urban VIII What you don't realize is that, while yes the metal is thicker, that thickness decreases as one goes up to the top of the pipe to help reduce weight. It's not uncommon for large facade pipes to not be made in a single sheet or one piece, but several. It takes several strong workers to roll it and form it on the mandrel. The metal composition must be absolutely correct depending on if it is to be tin or lead (or even other metals. Any error will make it too soft. The metal thickness has to do with the opening of the casting trough, but the metal is then planed and scraped to the desired thickness. Like all pipes and most especially facades, they have to be amply and rigorously racked in several places of its length to prevent any sort of movement.
gibts gefähr zu den Orgelbauern wegen dem Blei und so, oder ist es einfach einer die Berufsrisiken ? ⊙﹏⊙
I feel as though they should be wearing at least latex gloves and dust masks to protect themselves from lead poisoning... just a little.
Nah ... that's for wimps!
How did i end up in this place!?
+nitramdh i'm right where you are, click on a few "related Videos" and boom
@Orgelix weißt du zufällig wer das ist?? Ich mine der, der die pfeife macht. ich mache nämlich bald ein Praktikum dort.
@Orgelix schon erledigt...der die pfeife macht ist heni und der andere gregor.
Risky Biz! Where is OSHA in GB???
This is in Germany
0:32 Is It sand?
yes
I never realized organ pipes were made of lead. I always thought it was brass or bronze.
not lead, is zinc and stain
@@alejandrodmsosa no its lead and tin alloy
