Help me brainstorm some Miraphone parts order add-ons

[bloke]

I’m getting ready to order some really special (custom o.d.) tubing from Miraphone, as well as some parts that are not stocked in the United States by any of the jobbers. I’m trying to think of a few things that I will likely need/use - that I can add to my Miraphone parts stock - that are small and will fit in the same small box as the parts that I’m already buying… As shipping cost is somewhat of an issue.
How about helping me brainstorm such a possible list of likely-needed items?
(No… I’m not soliciting any orders. I am not a parts store.)… and I’ve already thought of some of those weirdo piston valve guides, as well as two or three 186 1-3-4 tuning slide bows.
I will not be ordering links, as I purchase those directly from Minibal.
QUESTION: Does anyone happen to know how close-to-compatible Miraphone two-sided-hole stop arms are to Amati/Cerveny?

Thanks!

I really like the lower 5th crooks and the doglegs. I have used a lot of them on a number of tubas. I have also developed a taste for their 186 crooks in nickel silver. Very sexy stuff, heh, heh…

003613200123

186 - 5th Crook - Yellow Brass

003612200123
186 - 5th Crook - Nickel Silver

And here are the other crooks in NS…

003612100014
186 - 1st Crook - Nickel Silver

003312000370

186 - 2nd Crook - Nickel Silver

003612200038

186 - MTS Crook - Nickel Silver

Here is the 5th dogleg and the other oddball piece…

003613200250

186 - 5th Dogleg - Yellow Brass (connects upper and lower 5th slides on the outside of the machine)

003313400183

186 - 5th Double Knee - Yellow Brass (connects the 5th casing to the lower 5th slide inside the machine)

If you use a lot of the 1st slide crooks, the braces are nice to have…

003312000844

186 - Brace - Nickel Silver - 1st Valve (post = 40 mm X 8 mm, with foot plate #3 on both ends)

If you ever need a long, quicker tapered leadpipe in NS for the Miraphone .769" bore, then here is the 188 pipe, unbent, in NS. I do not know whether it comes filled or annealed or whatever. This was the info I got from them. I paid to have them bend if for me to the 186 forms, so I never received an unbent pipe.

003612200005

188 - Leadpipe (unbent) - Nickel Silver

And here is their mouthpiece receiver…

003312000320

186 - Mouthpiece Receiver (15 mm) - Nickel Silver

If you have a part number in brass and want NS, usually you can change the sixth digit to get it. Yellow Brass is a 3, NS is a 2. I imagine they have other metals like GB or RB, but I do not know what number would be used in the sixth digit of the PN. Eva generally can find out anything for you. Once she understands what I am trying to do she even will suggest something that is better that I don't know about. (But you already know that from your dealings with her and Petra and Christian, of course.)

Do you still have that parts list I compiled? If not, let me know and I will send you a private link. If you know the YB price for a part, having it made in NS usually doubles that price. (Again, I know that you probably already know all this. I am just being thorough.)

Thanks.
I have it.
I'm just trying to think of stuff that I might need for run-of-the-mill Mirepairs.
I might even order some DVS links.
When they break, people just want them replaced...and almost never "converted"...particularly not schools.

I'm fairly certain that they (as do most European shops) use lead for mouthpipe bending.
Manufacturers have attempted to send me lead-filled 'pipes in the past, and USA customs turned them back.
Cerrobend to the rescue.

I wonder how much they want for (often missing, on roughed-up Mirahorns) bottom bow keels, these days...(??)

Mostly (again), I'm thinking in terms of "stuff that will fit into a small box - with the other small stuff I'm ordering.

They're being VERY nice, and making me some 17mm o.d. (16mm i.d.) nickel-brass tubing.
This fits the compensating side (inside slides) for most of the makes of large-bore compensating euphoniums...
Per typical (with so many of their instruments), Miraphone boasts .2mm larger.

I'm trying to think of all the little parts from receiver to bell rim that get lost or damaged, as they may be able to pack them between the larger parts being ordered:

The little grub screws in the bottom of the older bottom rotor covers that help align the rotors? Or for that matter, rotor covers generally?

The knurled nuts that go on the end of the long bolt that ties together the linkage pivots for the paddles? Or the bolts themselves?

Linkage springs for the paddles?

2nd slide pull rings?

Main tuning slide bows, ferrules, and tubing to adjust the length of the main tuning slide when players change out the bell for something else, whether after a crushing accident or just desiring a different tone?

Receivers and receiver brackets?

Linkage and rotor shaft/spindle screws of all kinds, including the smaller top stop arm plates?

(Yeah - look at the pictures of my Bessophone - that's where I got the ideas)

' good suggestions...I have some of that stuff (which USA jobbers stock, and I have - lazily - purchased from them).

Most Miraphone "receivers" (rotary models) are simply nickel silver tubing "over-parts" which protect the actual receivers (flared/formed out of the small ends of the mouthpipe tubes).

Typically (certainly school-Miraphone-wise), the small ends of mouthpipes (186, etc.) are rotted out and the mouthpipes crack off (PAST the receiver area), whereas the "receiver overparts" never really need replacing, YET (due to the mouthpipe tubes themselves being "toast") are discarded.

I wonder how much they want for… bottom bow keels…

The last one I bought was right at $50, but I am sure it has gone up. I can't find the part number, so it was on an order placed in 2018 or thereabouts before I started compiling my little list.

OK… I guess the school 186s will need to settle for 7-inch sections of sousaphone guard wire - with points on each end.
