Soldering a trumpet (brass)

One very critical point is that the mouth pipe is the most important part of the trumpet, tapered to specifications and computered soldered so there's no solder seepage blocking the air flow. IMO the pipe shortening should have been at the other end of the mouth pipe where the taper ends.

Hello, thanks for posting this but we can't see the actual soldering! Could you maybe do another one please?

I was looking at the trumpet mouthpiece in the receiver - it doesn't seem to fit as far into the receiver as it should, but I play with a man who had this problem with his trumpet, so it does happen.

Wouldn't it make more sense to shorten the instrument from the tuning slide and stockings? That way not to mess with the venturi and taper of the mouth pipe. This seems to me as if creating a gap from where the mouthpiece receiver and mouthpipe meet which would result in poor performance.

How does this affect the lacquer coating around the area in which you are working? Does it melt/burn it off? Do you have to re-coat again after you're finished?

Viron tseven If you look closely, you can see he did almost no damage to the lacquer.

+Viron tseven depends on the brand. Some brands have more sensitive lacquer. But if you get in and get out quick you can avoid burning the lacquer. If you do, you can then refinish it and spot lacquer it. It is a risk when you have to resolder braces that there might be some permanent disfigurement. Moral of the story......don't break your trumpet.

+Atochabsh +Brad K Do either of you know if this is the same steps for soldering the front and rear bell braces? It's for a Cornet though but not sure if that makes a difference. I'm good at soldering, I've just never worked with any musical instruments before.

+edoubleu52 use wire to hold the braces in place. But make sure that all excess solder is off the brace and the place on the trumpet where it was. If you do not do this, the braces will not fit flat again. You can use either the liquid flux like in this video, or paste flux. It doesn't take much to do the job. If you take your solder and flatten the end you are working with, it will be easier to administer the minimal amount and stop from getting extra solder all over the place.

@@Atochabsh Good afternoon friend, could you give me a tip on soldering flux which is the best type to solder an instrument?

I have been repairing copper for 30 years. but I have never had such a beautiful heating lamp. In Romania we are older and I don't care much! I would like something less powerful and practical.

Why to disconect that pipe joiner fully while you could live it on trompet

Did you use flux before applying solder

@snrnsjd 4 ай бұрын

no flux equals no connection. Allways use flux, liquid or paste.

What tin alloy using?

@Atochabsh 8 жыл бұрын

+macucapa Its usually 60/40, but you can use a higher silver solder for silver plated instruments. That has a higher flow temperature.

Thanks for the demonstration ... the camera position, however, makes it hard to see everything you did clearly, and sometimes you're completely obstructing the view of what you're doing.

Just an observation about sanding the tube. Why did you not consider taking off the valves and slides so the grit from the sandpaper does not make a gritty mess.

I'm probably wrong, but it looks to me like you are using a trumpet mouthpiece in a cornet. if you are, that would explain why the instrument played flat.

@cyborgjonny 7 жыл бұрын

Is it not the same?

@rayvignovich1288 7 жыл бұрын

No, it isn't the same. A trumpet mouthpiece is longer and has a thicker shank than a cornet mouthpiece, so using a trumpet mouthpiece in a cornet will make it play too flat.

@williama9856 7 жыл бұрын

Looks like a trumpet to me. A cornet would have a wrap around the 2nd valve slide.

@rayvignovich1288 7 жыл бұрын

The difference between a cornet and a trumpet is that a cornet has conical tubing. Some cornets look exactly like a trumpet, such as the Olds Mendez models. And cornet mouthpieces can have long shafts or short shafts and the early olds cornets had their own size mouthpiece. All that being said, to my eye, the trumpet mouthpiece in this video doesn't appear to extend into the receiver like it should. I think it looks like it's being inserted into a cornet receiver. Anyone considering making this modification to an instrument should first of all determine if it takes a different sized mouthpiece, and secondly, the extra tubing should be removed by trimming the fitting of the tuning slide. That’s more work, but you avoid problems with the pitch.

@williama9856 7 жыл бұрын

Ray Vignovich Your totally right about the conical tubing, and the silliness of this repair. I just don't see a cornet in this video. All we see is the side with the bell flare, and that's conical on both trumpets and cornets. The tubing begins to flare out as soon as it turns up.
