- In this episode, we discuss piston/casing repair and how to size for a custom mandrel. Topics such as- When do you use a reamer on a piston casing? NEVER. And others discussed
Thanks for watching.
Very informative and entertaining. Thank you, Mr. Lee.
Buy an expander just to throw it away in the video xD
Great videos. Always amazing to see a master do his craft.
Incredible repair!! I love the videos look forward to seeing what’s next!!
Thanks for watching and following along
I really enjoy your videos! A great artist doing his work is a cool thing to watch!
Great job, that you are doing! I can't stop watching you! Wish you all the best from.... Romania!
I love your videos, Wes. fantastic work. thank you.
Educational as always... Love the "Groovy Gravy" comment!
Haha thanks for watching!
you got golden hands! Bravo!!
Sou um trompetista do Brasil e adoro seus vídeos.
Amazing work. Just took my son's euphonium for repair with the same problem..
Love it, Wes!
You always make it interesting Wes !
Thanks for watching!
Nice work!
Fantastic!
"Mouthpiece dent in the casing"
Yeah, I can relate.
I brought my primary trombone (King 2B, for jazz lead, and classical tenor and alto parts) into my local shop a few years ago for slide work. The local shop is Osmun Brass, in Acton MA, about 2 miles from my house. Their work is superb.
I opened up the case at home, and immediately dropped the mouthpiece on the bell. Crap.
Well, the horn is due for slide work again, so I'll point out my mouthpiece dent when I bring it in.
Que bien, y que buen Lutier...

GREAT JOB WES...BESIDES U SHUD ADD-OVEROILING CREATES VALVES STUCK
Hi Wes. Trying to figure out what to do now with my nice reamer that I happily bought from Allied years ago. Maybe use it to crack walnuts? Also, regarding your Wes's Fancy Valve Oil ... you do provide a bottle to your customers with the horn? Otherwise they'll just go back to using the commercial stuff from the music store. Thanks again :)
hi, what liquid do you use on the ultrasonic? thanks
Can you tell me what the tool was you used to get the 2nd valve slide out? Thanks!
👍
👌👍👍👍👍👍
Amazing. I’ve done a few valves myself and those casing mandrels are a god send. Quick question. What’s the chem clean solution that you use?
If I recall correctly, Les did two videos that showed the chem clean procedure. They were back a couple of years I think. If I remember correctly, the first was a "soap solution", followed by a descaler for lime. Slides and valves go in the ultrasonic then the soap solution. Rinses are in between stages. Here is the title to search for : "Chemical Flush- Wes Lee Music Repair" and "Clean, Sanitize, Disinfect- Episode 22- Wes Lee Music Repair - cleaning in the face of corona" The first one is a couple of minutes, the second about an hour. Hope this helps you.
We need to get you some new shop towels. 😄
Why you always hatin on my lucky towels?!?
@@wesleemusicrepair9820 lucky to still have those we got 28 years ago.
Hi, great video. I’m wanting to attempt a similar repair in a junk trumpet and need to know which size mandrel/s I should buy.Could you clarify a few things for me?
You measured the piston at 0.664 of an inch, however, it wasn’t clear what size the interior of the casing was. I assume it must have been slightly larger to allow clearance for the piston. You also didn’t say what size mandrel you used. Was it a 0.664 mandrel (same as piston) or was it larger to match the casing?
I should mention I’ve measured my own piston to be 0.660.
There's a chart in the Ferree's tool catalog listing the casing size per manufacturer (e.g. Reynolds/King/Holton= .660", Olds/Bundy=.665"). Search for "Ferrees Tools Catalog pdf".
Thanks very much!
Very interesting. I hope you don’t mind a question and a comment. Maybe two questions. I started on a trumpet many years ago that had springs on the bottom that pushed the pistons back up. The Yamaha trumpet that I have now has springs on the top that lift the pistons back up. Is one system better than the other?
I managed a QC department for some time. Our method of using the telescoping gauge was to tilt the shaft just a bit and then gently tighten the gauge. When the gauge stem was then aligned with the bore, the gauge was pushed slightly farther into itself. We thought this guaranteed best contact. You did not do this. Is this because the piston sleeve on the instrument is delicate? Just curious, not criticizing.
I enjoy watching your videos!
Thanks for watching.
As far as springing, there were several different styles throughout the years but they all seem to be top barrel sprung now.
Do you notice a difference or have a preference? Interesting topic for sure.
As far as using telescoping gauge, I only showed taking one measurement in the video, if I were trying to get an accurate size for making a custom mandrel, I would take multiple measurements up and down the casing. Much like what you’ve described.
Wes Lee Music Repair thanks for responding. I am not sure that I have a preference on the springing. Partly because I was much younger with the bottom spring. One thing I do remember is that if the valve got a little sticky, one could take the bottom cap off and elongate the spring. Likely not the best idea, but what do third graders know about such things.
Hey, you do what you have to in a pinch! I think everyone has stretched a spring! Ha
It looks to me like all the newer instruments, like the Yamaha you mention, have it where the spring is on top and it pushes the piston back up from above. There must be some advantage to this, but I can't figure out what makes it better (can anybody comment?). And yes, you can still stretch the spring; it's just a little harder to get to it in these new pistons ... but I would think if the piston and casing are clean and there's no obstruction, you shouldn't have to.
@@wesleemusicrepair9820 Hey Wes, do you have any ideas about why the top-barrel spring approach is so widely used nowadays? What makes it better/more efficient?
Fun fact: (although nothing to do with instrument repair) Popeye’s Chicken was not named after the cartoon sailor but the lead character in the film The French Connection. Don’t believe me? Look it up.
Nice video by the way.
Glad you threw those garbage reamer out.👏🏻😅👍🏻
Found that in a junk shop, I know it’s old but looks like it has never been used! Haha I guess the previous owners couldn’t find a use for it either!
Those reamers were ment to cut inside the valve casing when they are assembled from scratch , not for repairing a finished product
@@erniearruda8861 agreed. They have no place in repair. But I do use them in sizing parts that I’m making
@@wesleemusicrepair9820 Hey again! Somebody should inform Allied about how bad these things are ... the catalog says "The toughest valve repair job is made easy ... " and: "You will pay for this tool [I think they were trying to say "this tool will pay for itself"] each time it is used by saving time and by doing an extra fine quality job."
I have a rotary valve Bb tuba but the head of the big screw that holds the arm down is sheared off
That can be taken care of!
@@wesleemusicrepair9820 how difficult is it to remove it
Honestly, some are harder than others. A lot has to do with the threads and how well they were made.
It is not a super expensive repair though. What brand of tuba is it?

Sorry, but I have to disagree with you about the burnished/reamer tool. I used them for 42 years and never damage an instrument. Great tools.
