Do you want to leave a tip so Art can continue to make more quality videos?

I play euphonium, but I don't repair myself. I've always been fascinated with instrument repair. Getting an instrument working that has tolerances of less than a millimetre is more art than anything.
After 3 years I finally could have my own initial kit of MDRS.. I've been waiting for so long 😅 thanks for your videos!!!
How much it cost?
Where did you get it?
Thanks for taking the time to make this video. I find it facinating to see the specialised tools for instrument repair work.
Good job. "Body work" is time consuming and requires: time, money, and is an art.
Fascinating! Another great video, thanks so much!!!
One of my all time favorite videos☺
Good video, thanks!
I've always wondered if a system like this might be used to remove dents from steel bicycle frame tubing. Steel is much less malleable than brass, but with a strong enough magnet and a 27.2mm ball it might work on a thin-walled steel frame.
Well, for one the magnet would stick to the bike frame!
It works (kinda) on brass instruments because brass is 1) non magnetic, 2) malleable and 3) thin walled. Even then it's a bit hit and miss, the bigger the ball you can use the stronger the bond and the more effective the action, and a 27mm ball is on the small side even in this application.
Would it help to anneal the brass first? It would be somewhat re-tempered when it is rolled out. Any lacquer would be cooked I imagine.
tnq very much ❤️
Can you do a video on rethreading tuba valve tube?
Art how does one control thinning of the brass or when to anneal or not? I would imagine there is some visible signs that let you know it has been worked enough.
It is very difficult to anneal because the heat burns the lacquer and melts all the solder joints. Because of this, usually annealing is only done when the instrument is already dis-assembled for an overhaul. You know you need to anneal when there are serious dents that require a lot of work or when you can feel the brass getting hard to work.
@@TheBrassandWoodwindShop Thank you Art.
That is one powerful magnet. You've got some good moxie to get that ball off. I was getting tired just watching. LOL!
What is the power of those magnet and can they work with trumpets, horns and trombone slides?
Thanks!
I am not sure what the power is. They do not work well on smaller tubing. They really only work well on baritones, euphoniums, sousaphones, and tubas.
If only i was watching this for entertainment and not because i have to do it.
Why not cover the magnets with a felt so that it will not damage the lacquer finish? A spray adhesive will allow you to add a circle of felt that will protect the magnet and the instrument and not effect the magnetic properties. Plus it will glide over the instrument smoothly.
Felt will collect dirt and metal filings and scratch the instrument. I use an old drum head with trombone cream between the magnet and instrument.

Wondering, how do those dents affect the sound?
JIM 🤔
I've seen people rope calves with less energy spent than wrestling against that drum head.
Wow. How long has the dent ball system been around?
I am not sure, but I think it is around 30 years.
balls are expensive
Mister repair man.thumbs up !.
