I repaired band instruments for 40 years and never ran into this problem! Now that I'm retired and only working on my own horns I have to solve it!
I just bought a NOS Jet Tone Buddy Morrow model 1 mouthpiece. I like a lot, bit it wobbles in my 20H. My other mouthpieces do not. What's the best way to get rid of the wobble?
Thanks in advance for any and all advice!

Buy a conn 3 mouthpiece 

i keep a roll of Teflon (R) tape.  A couple of wraps should fix it.

Something about the taper doesn't match the receiver.  Maybe the shank was repaired and flared out.

Coat the shank of the mpc with dykem and remove the high spots until it fits.

The Jet Tone Buddy Morrow is a nice mpc, but it does not fit in any horn. Did Budd Morrow have a special leadpipe? I did have the same problem, I just gave up. I think I gave it away.

Wonder if it was set up for the smallish Olds receiver?

I finally got my courage up, chucked it up in my lathe with a live center, and went to work. It was too large at the very tip of the shank. I slowly took it down with 500 grit paper, followed by 1200 grit, and 2000 grit till it didn't wobble anymore. Then a light polish. Not sure if I will re-plate it yet. That might just make the problem re-occur!

It was interesting to find out others have had the same problem.

No problem now. And I'm really liking the way it plays!

If the end of the shank plates up too much, that's a problem of improper anode placement.  If you were down to brass, somebody forced something into the end of the mouthpiece (maybe bad chucking).

I wouldn't bother replating the end of the shank.  Doug Elliott doesn't plate his shanks and they work fine.  The place you really need the plating is on the rim and cup.

Hello everyone
Mike from instrumentinnovations . If it was damaged do to someone trying to repair it . All could have been avoided if the person who fixed it would have used one of my mouthpiece repair sleeves . They are designed to match the taper on the O.D. Exactly so when you insert the repair tool you cannot flair the end of the mouthpiece . Any one can use them they are quite fool proof. You simply tap the sleeve onto the damaged mouthpiece  then insert the repair tool. Do not hammer the end of the tool into the mouthpiece as it will lock the tool together and will make it difficult to remove the stuck tool. What you need to do is strike the tool on the side opposite of the dent . Towards the dent and the dent is repaired the mouthpiece stays or is returned to round. A sleeve for tenor or bass trombone sells on my website for twelve dollars each. We have a year end special for the whole repair system for sixty bucks that includes the repair tool Delrin dent hammer and nine sleeves . French horn ,flugelhorn ,euphonium ( doubles as a trumpet sound sleeve),cornet, trumpet, tenor trombone ,bass trombone,small bore tuba, large bore tuba..
Thank you all for your support and Merry Chistmas

My '80's Buddy Morrow had a perfect fit on my Bach 12.

And my 70's one fits my 2B plus fine too

I think you are right. Probably a plating problem. I'm surprised they didn't have better quality control! But now it's fine and this mouthpiece is a keeper!
