Hey, Owners of CC 186 and 188 Tubas...

Postby the elephant » Fri Dec 21, 2018 3:52 pm

I am trying to convince someone of something. I need photos and information. If the photos support my idea I will rub it in the face of my friend. If they do not I will eat some crow the next time I see him.

I need a clear, well focused and lit photo of the side of your horn showing the initial bend from the valves up into the leadpipe. Er, I guess that would be the FINAL bend from the top bow down into the valves. (Six of one, half a dozen of the other.)

I do not want any photos of BBb 186 tubas because the leadpipe is not the same shape in this location.

I need to see the shape of the bend, and with a 5th valve slide in place you cannot really see this directly from the side, so maybe from a 45º angle, if you could?

Here is a photo showing the area I need to see.

This is a four-valved CC, so you can easily see the difference in the curve as the pipe leaves the valve and heads up to the top bow from the side as there is no 5th slide loop in the way. I need photos of what this curve looks like on *your* horn/s, from whatever angle you can get that nets you a clear photo showing this curve in your leadpipe.

Again, only 188 and CC 186 tubas, please. :tuba:

THANKS!!!

Thank you for the bump, Mike! I really want photos of 188s, but any of the modern 186 tubas will also be welcomed. Original, classic 4 valved 186s are also sought. I want to compile a folder of photos of several parts of these tubas for comparison purposes, to be made freely available to anyone who wants a copy, but I have to have photos for that folder. Please take a few minutes with your 186 CC or 188 to snap and upload some photos to help our our community. (Meaning *ME* for the time being, until I have compiled my examples, at which point I will upload them and put a link in my sig line.)

Thanks, everyone!

K5JMH's is an example of a 1960's four-valve 186 C tuba, the mouthpipe tubes of which were bent differently from the (not commonly sold in the 1960's) 5-valve 186 C tubas of that era (the 5-valve mouthpipe tubes of which have been bent in the same place from early to now). As can be seen from K5JMH's picture, it would be a bit problematic (perhaps, cutting a curved chunk out of a .772 bore slide crook to use as the connection ferrule, combined with bending the cut end of the mouthpipe tube upward significantly) to reuse a 1960's 4-valve bend 186 C mouthpipe, and add a fifth rotor.

Image

Since that time, 186 C mouthpipe tubes have been bent the same for either the four or five valve versions, as is seen with this early 1970's NOT-rotted (originally made for a) four-valve 186 C tuba (the BROWN one), which is replacing the hopelessly rotted one - removed tonight from a 1980's era 5-valve 186 C (when Miraphone began expanding the bell pancake and rim diameter out to 450mm).

Image

Apparently, the interest/wager/whatever here concentrates its interest on 188 model instruments...

...but the significant difference between the two 186 C mouthpipes shown in the pictures in this post (though they are bent identically) would not be in their bends, but in the taper. The NON-rotted early 1970's 186 C mouthpipe (again: the BROWN one) exits the receiver overpart at 13.4mm o.d., whereas the later-made (hopelessly rotted) one's o.d. at the same point is 15.05mm. ...and the significance is that the 15.05mm is a ho-hum-sounding mouthpipe and the early 1970's smaller 13.4mm-originating mouthpipe (which will be installed tomorrow or the next day) will (based on all of my past experience) absolutely make this 1980's-built 186 C tuba ROCK...even with the extra 15mm of (assumed to be sound-mellowing) bell pancake :shock:

Thanks for the great 188 detail shot, Raul! (You let me play that horn a couple of times and I loved it. You got a very nice example.)

Hope you guys all are well and had a great holiday season!
