above: Before pics of this Besson Compensating Euphonium
This is another, old, abused and fantastic instrument. It has REALLY been put through the ringer, but I hope to breathe some new life into it. Let's have a look at it, and see where we are at right now. As always, click on the images for a larger view.
First, this horn has quite a few loose solder joints. They are noted with red circles and arrows. The specific locations are;
- 4th piston tubing leading from the piston to the tuning slide
- 3rd slide knuckle to left side outer slide tube
- 4th piston shorter tubing on the back side of the horn
- 2nd slide leg
Obviously, this sort of thing makes it difficult to play, so the instrument is going to have to be taken apart to properly repair it. How far apart? This far...
Was it completely necessary to take it this far apart? Yes, because to properly re-solder those joints, they must be taken apart to be properly cleaned and prepped for soldering. This also conveniently allows me easiest access to the nastiest dents that are in the knuckles.
Below is a good indicator of a bad solder joint. Notice how the color on the inside of the ferrule is green. This is corrosion between brass that is caused by moisture, which means that this joint has been loose for some time.
