I would suggest to start with a phone call, because they probably only deal with companies they know and have deals with.

I just sent an email to them requesting info for a 5 rotor set in 19.5 mm size - the kind that are front loaders, not the traditional design where disassembly is via the back.
I have a knack for sending emails that get lost or that take forever to generate a response. I wrote in English, figuring that someone over there will be able to properly translate the message. But I do not have high hopes of a timely reply. It might happen, but then…
Anyway, does anyone have recent experience buying from these folks as an individual? I know they are not inexpensive, but they are also supposed to be of a very high quality.
Anyone want to share their experience here?
Hi elephant,
I've seen you posting parts-related questions a few times in a couple of days.
Help us out in our curiosity, are you planning to make a kind of "Frankenhorn" or some kind of a tuba conversion?
Just curious, in case you want to share it with the forum.

Nirschl uses a front-loading rotor for the 5th on some of his tubas. It's probably made by Meinlschmidt. I don't think those 'front-loaders' are quite as robust as the conventional rotors but one thing is for sure.... the front bearing can be renewed by just replacing the bearing plate.

I think we need to talk Rick Denney into starting his own small "do the math for us" business!!

Oh.... Wade! One thing you need to remember even though the rotors come out through the front of the housing... You still need access to the backside of the housing. The ones I've seen have a hole in the center to give the rotor a little 'help' to push out the front bearing plate. I had a Nirschl in the shop a couple of years ago where a tech tried to pull the 5th rotor out by gripping the stem and BROKE THE STEM OFF!

Tubas are so weird (and that's a mathematical assessment of the impedance of a conical taper) that I suspect a piece of 3/4" vinyl tubing is a far more useful tool than a calculator.
