TromboneChat

Surprised to see that there's literarily no information anywhere on the internet (please forward me if I have missed it some corner) about Nils Landgren and potentially other trombone players water key solutions.

He describes it himself here:

He states that it's, quote "a piano thread running through here"

Has anyone on this forum tried to DIY this Yamaha implementation? Interested to learn what parts you bought if you don't mind sharing.

Much appreciated.

Thein uses that waterkey design.

Thanks for the reply Bonearzt - You're right! I can see the mechanism here: https://thebrass-exchange.com/content/t ... make-fbbeb

I wonder where one could buy such parts though. For my plastic trombone I guess I could 3d print something but harder for my real Alto...

Long waterkey mechanisms have been common in Germany for many, many years. They are not exclusive to one maker.

My first teacher also has such a long water key on his Lätzsch trombones.

As an 8 year old beginner I was so fascinated by it that it was clear that I would need something like that later.

Later I had it retrofitted by Lätzsch.
A very thin tube is soldered onto the slide and a wire is pulled through it. If you then press the top, the flap opens at the bottom.

Thanks for interesting context Matthias! Cool stuff - Considering people mentioned Germany, I was able to find this: https://shop.mtp-music.de/article-detai ... 30-k1.aspx

Might give it an order. I'm more so interested in doing a DYI here. I have some soldering experience and my trombone isn't all that expensive. I do see how taking it to a renowned brand like Lätzsch could garner a great result though.

That is not the same thing. That is a device where you drill a hole in the existing waterkey lever. The string is located on the cross brace. You pull on the string to open the key. It can work, but ..

I see. Hmm. I wonder where you'd get the parts then. My search continues.

Listen to Matthew regarding the MTP/Seibold device!

Page 28 of the B&S spare parts catalogue has the parts, as used on their MS14 and MS27 trombones:

You'll have to find a Buffet dealer to order these parts for you though. And parts are not cheap these days!

I seems to me that something that pulls would be better. Pushing a rope is always a bit slow.
And soldering a tube on the slide seems like new alignment problems.
I would love one of these.

Here is my design for a remote water key. I used it for 20+ years without any problem. It's easy to dump water in outer positions without having to remove your left hand from the trigger position. It was fabricated by Wayne Baughman, a local tech at the time. The weight that it added to the slide was negligible.

For every emptying action, you have to both open and close. So push/pull vs. pull/push probably makes no difference.

I had someone replace my spit valve with a trumpet one and put a little ring (think it's actually from the spit valve mount) at the top of the slide, so it's just a direct pull. Works really well- just need to tighten the fishing line once or twice a year.
