How did you make changing the rotor bumpers look so easy?! Great video to raise awareness of the need for annual cleaning and very satisfying to watch! I will definitely be showing this to my students :)
I loved how you had a brush used with the electric screwdriver. That method should really get the interior of the slides nice and clean. Speaking of which, why didn't you do the brush cleaning before putting the Horn and slides in the ultrasonic cleaner? Or, does the cleaner help loosen things up for the brush/snake? Finally, I noticed the 1st valve F slide was broken. It would've been great to see how you repaired that problem as well. Thanks for the video!
Hello, what is the solution (acid?) you used for soaking the french horn in? I mean to the liquid that was in tub in which you put all the french horn parts for removing layer that got stick to the inner sides of the french horn's tubes? Thanks a lot.
It depends on why the horn is red. If it's a large, brownish-red patch, it's probably just oxygenation in the brass. Nothing to worry about. If you have small bright red dots, that might be red rot. Show that to a repair technician. The detergent is called Simple Green.
Someone already asked, "Hello, what is the solution (acid?) you used for soaking the french horn in?..." and the answer was, "It is a detergent. The ultrasonic waves from the machine do most of the work."
Bro I honestly didn’t know instruments needed to get cleaned… I assumed the insides were supposed to look like the Statue of Liberty lollll imma clean my horn and trumpet tomorow Ig
May i know what those yellow threads are that you tie in the key levers? Thanks to your video I finally managed to disassemble the cylinders of my old F and Eb horn. I dipped the cylinders in apple cider vinegar because I can guarantee you that it dissolves the oxide in an incredible way. I also used pipe cleaners to clean the pumps internally. Tomorrow I should reassemble everything. I hope I haven't done any damage.
@@dartme18 I sometimes do it on slides with white vinegar in my ultrasonic cleaner. Just make sure you DO NOT use the heater function as it will remove the lacquer! Don't ask me how I know...
Is it safe to acid wash the rotors? Does contribute to the eventual wearing down of the rotor? Engelbert Schmid on his website explicitly warns against using acid to clean the rotors.
Quoting: _"Wipe the rotor and casing clean with a cloth. The remaining deposits and the dark oxidation should not be removed. Cleaning the rotors in an acid bath is wrong. The sealing surfaces should never be lapped, or even worse, polished."_
And he goes on further in the specific maintenance page: _"Never you should lap the inside of the valve, and also never (one million times never) put the rotor into any bath for removing the lime deposit, or even worse polish the rotor! There is no bath on the world which takes away the lime deposit and does not remove metal! Even if you only take away the oxidation it’s a loss of metal! Very quickly you reach the barely acceptable 8/100 tolerance, and next time already the not any more acceptable 10/100 mm! Be aware: If you only take away 1/100 of the material, this amounts on 4/100 tolerance in diameter already (1/100 on each side of the rotor and 1/100 on each side of the casing)! You have reached the 10/100 mm tolerance and have destroyed the instrument!"_
He has a really strong opinion on this, as follows: _"And this as a “specialist”! You should be made responsible for an replacement instrument and you should be banned from your profession! Please don´t be shocked, but think about it! At the end you will be grateful to me for this brusque hint!"_ _"Turn the calcium covered rotor in its own soup with a crank lever at the upper bearing plate taken away. This way you chafe the excessive lime deposit and wipe it away with a cloth! The remaining lime deposite is positive! It makes the rotor rounder (no turned part on the world is absolutely perfect!), the film of liquid in which the rotor is swimming is more even and the valve is running better! Excessive lime deposit you remove with a scraper tool."_
@@DementedEeyore64 2:14 Are you sure this container is an ultrasonic device and that causes the bubbling? It's hard to say, because it doesn't say anything.
Careful when using a snake. Don't use it on the lead pipe and when snaking from the opposite end don't snake past the joint where the lead pipe is soldered. If the end snaps off it's a real mother getting it out.
@@HoughtonHorns thank you.... Another Question.... I am looking for a Video or pictures about the Valves of a Lewis.(How they look like) Do you have an Idea? Thank you
После очистки инструмента внутри, я заливал в него теплое молоко на несколько часов, оно, окисляясь, дает осадок, на котором затем формируются звуковые кольца, появляюшиеся во время игры на инструменте
2:06 delicious deep fried French horn
the flavor was immaculate

Agreed: do gross cleaning before fine cleaning. That is, wipe and scrub before ultrasonic (some wiping after ultrasonic, too...).

It is a detergent. The ultrasonic waves from the machine do most of the work.
Can you please tell me exactly what liquid is it for ultra sonic , great job 🎉
PUSH DOWN THE VALVES WHEN TAKING THE SLIDES OUT
YEAH
I WAS GONNA SAY ITS ALSO ALOT EASIER IF YOU DO
Omg this, it was a little painful hearing them pop
It is not necessary and does not harm the horn in any way.
Several Asking about he model. Yamaha 871 (briefly visible on the repair ticket).
0:19 Looks like one of the Slides popped off the Tubes
Please tell me how to remove redness from the French horn after cleaning. And what detergents do you use?

Just wondering what horn was used in this video?

How did it go? Did you try ultrasonic cleaning in vinegar?
@@dartme18 I sometimes do it on slides with white vinegar in my ultrasonic cleaner. Just make sure you DO NOT use the heater function as it will remove the lacquer! Don't ask me how I know...
What oil do you use on the inside of your rotors?
Como se llama el material que saco todo el sarro dentro del corno??
Good afternoon friend, did you get the answers?
Hold down the valves when taking slides out！！！！
I had the same thought
It is not necessary and does not harm the horn in any way.
Why?
@@dartme18i dunno, but probably to let out the vacuum seal by opening them
0:19 😳 that's not supposed to come out like that
hey Mark, it should be polished, right!

No acid wash is ever used in this video. Its an ultrasonic cleaner and detergent. In other words, soapy water.

Hello, how are you? Do you also sell used horns or do you only maintain them?

Hi there! We do it all: houghtonhorns.com/product-category/pre-owned-horns/
Hi Guys.... is this an original Lewis from Chicago?
It’s a Yamaha.
@@HoughtonHorns thank you....
Another Question.... I am looking for a Video or pictures about the Valves of a Lewis.(How they look like)
Do you have an Idea?
Thank you

さすがです❗
No way a professional is taking out the slides without depressing the valves, or were they stuck... 😭
Only thing I could figure is since they are going to clean the rotors, it is immaterial?
舒服
🤤🤤 - 🤢🤢🤢🤢🤢🤢🤢🤮🤮🤮🤮🤮🤮🤮
Good video but not really satisfying 🤮
