Did my first patch job

Post by Amconk » Mon Jun 29, 2020 8:31 pm

Had some rot on the F-attachment on my project horn, when I cleaned it up it left some pinholes that leaked air. I decided to try my hand at cutting a patch and soldering it on. Not too bad... I’d do a few things different next time but it turned out looking okay. Ugly but functional. Just need to buff it up now. Valve tubing seems air tight now.

I applaud you for even trying to do it yourself, let alone succeeding. Good job!

Great job! Now you can enjoy playing that instrument again.

It seems like patching is a lost art these days. Everyone just buys the replacement part and installs it.

When I was a kid, there was a repairman near Reading, PA who did a great job of patching. He would design many of his patches so that they looked like guards that were made at the factory. For example, if he patched a hole in a trombone tuning slide, he would construct a nickel guard that wrapped around the entire tuning slide and was absolutely symmetrical. His work was something to behold.

I saw a euphonium in a community band with little square patches on it. Turns out it was screwed to the wall at a TGI Friday kind of place as wall art. My buddy looked at it, found the valves still worked, so swapped the manager a junk alto for it. The little patches covered the screw holes!

Whoever originally mounted that perfectly functional euphonium to the wall in a restaurant should be punished to the fullest extent of the law. Now wait....there might not be any laws concerning that. Shame.

Great story Kingfan!

Well the metal under the patch was so thin that it collapsed when I messed with it. So here’s Plan B. Ignore the burnt lacquer on the ferrules, I’ll clean that up later.

If at first you don't succeed ...!

Persevere. ;)

First round of buffing. (Takes forever when you use a dremel. One of these days I’m gonna get a buffing wheel for my bench grinder...)

Getting better!

Looks pretty good to me!

(This is reason #2 that I do not buff).

I did buy a buffing wheel for my bench grinder, but that grinder is still sitting on the ground rather than on the bench. That's a good excuse for me to not bother buffing right now.

Cheers,
Andy
