Title: Building a BBb Contrabass, a Photo Essay
Post by: Slipmo on May 26, 2016, 12:12AM
Hey all, I recently commissioned my good pal and fellow shop mate, Brad Close (Blowero on the forum) to build a BBb contrabass trombone for me. Inspired from the 1901 Conn BBb that was recently here at The Brass Ark and with beer involved, Brad accepted my wacky idea. We're doing a dependent valve version because... why not!  :evil:

Anyway, parts are more or less all here now, scavenged from various sources and I thought it would be a fun project to document the process of Brad's build on here for all who are interested. It will probably be a while, as we've lots of leadpipe orders to fill and lots of repairs and other more important jobs in the pipeline, so I can't say how frequent I will update with new photos...but without further delay! Here are most of the slide parts, raw drawn tubing for bending, crooks, valves, bows and bell flare. Brad will fabricate all of the other necessary parts.

The inspiration:

Hope you enjoy the photo essay!

Ohhh..

I've been meaning to do this myself for a while.  Never bothered to plan it, though.

Source for flare and J bends?  Are they existing parts or special fab?

Cheers,
Andy

And some more interesting stuff... measurements off one of the Minick BBb contras (#2, George Thatcher's original BBb). Brad is doing his own design for ours, but cool to see how others have done in the past.

(http://i816.photobucket.com/albums/zz82/slipmo/IMG_4364_zpsuwzs8sst.jpg)

Here's that Minick Contra (which I sold for George a few years ago)

(http://brassark.com/sale/minickcontra_1.jpg)

Bell is a very early Miraphone contra prototype bell that I found in a pile of parts here in LA. It was never mounted. The J bends are also parts found in depositories. Slide tubes are from Conn. Drawn tubing is custom X large bore straight pipe sourced from one of my connections  :evil:
The rotary valves are from Marcinkiewicz.

I know, Miraphone slides are terrible, but I think its the tubes they use, not necessarily the 4x slide tubes. Of course 4 tubes are incredibly hard to align and the weight of it makes it slow... but the 1901 Conn had original 115 year old raw brass inner slide tubes and it worked surprisingly well! Hopefully using beautiful Conn slide tubes will yield a decent 4x slide  :good:

This one is just a single commission, so no plans to offer any kind of production models.

Good eye, Brad's gonna make that piece  :good: There are actually a lot of little pieces and braces not shown in my original photo (I didn't want to lose anything small while setting up the shot), as well as many parts to still be fabricated.

That's a different part - upper cork barrel assembly with lock ring. So of course Conn/Selmer, in their infinite wisdom, couldn't possibly ship that in the same box with the other cork barrel assemblies that are made in the same factory. :dontknow:

I play a Haag carbon fiber slide on my bass trombone...extremely light outer slide!! It just occurred to me that maybe that would be a great Idea for a BBb Contra.
I realize that  you guys are going for a classic look but maybe someone else could pick up on that for future builds? :)

Brad has been making some progress. The handslide is almost fully together. Outer slide is done and he's finishing the inner slide soon and the return crook. I'll post a photo when its all done.

Here is a question for those who know far more than I do-anyone can answer.

Is there any reason why the cross-over on the hand slide should be at the bottom of the slide?

When Noah started this topic, my mind went into overdrive; how would I go about building this (if I had the cash, the tools and equipment and the time-just remembered, I am retired so I've got the time, damn)(oops, I forgot the skill-I will never have that :( )
My version came up with the cross-over at the hand grip, forming a semi-contoured brace similar to that on the Williams trombones and the Martin Urbie Green.

In the early 1900s, the Salvation Army made some BBb contras with the cross-over at the hand grip as shown in the pictures on Doug Yeo's site:-  http://www.yeodoug.com/articles/trombone_gallery/trombone_gallery.html  I had the opportunity to briefly play one of these in a now, sadly closed shop in Birmingham, UK some years ago. It was remarkably easy to manage but, because of the very narrow bore, not easy to play. I hope that the one Noah is building is bigger than the sub-0.500in bore and 8in bell that this one had. :eek:

I will continue to follow this thread with interest.

Cheers

Stewbones

I think I see what Stewbones is getting at.

There needs to be one "diagonal" connection between tubes to move the path from the left slide to the right slide. Why make the diagonal connection at the end crooks? Why not make it at the handle? That way, the end crooks could be parallel to one another, allowing for more symmetry in the tubing of the outers?

He crosses over at the handgrip with a floating section to allow more compliance.

Post by: BGuttman on Jul 06, 2016, 06:57AM
Doesn't change the fact that the slide crooks are parallel rather than crossed.

Since the crooks on the old Conn were crossed and that was the model, I don't see why you couldn't use the same pattern.

Crossed crooks will allow the mouthpiece and connector to be closer to the bell.  Is this important?  I don't know.


Title: Re: Building a BBb Contrabass, a Photo Essay
Post by: bonearzt on Jul 06, 2016, 07:45AM
IMHO,  crossed or parallel crooks won't matter unless you're REALLY into asthetics.  Then you can have it built to your liking at your expense.

Also,  I don't think the mouthpiece position in relation to the bell would change much with either config.

IMHO,  crossed or parallel crooks won't matter unless you're REALLY into asthetics.

I've nothing to back it up, but crossed crooks always seemed more mechanically sound to me; viz. the point of maximum stiffness is out on the floppy-around end of the slide.

Post by: Slipmo on Aug 15, 2016, 04:35PM

Brad really wanted to make a seamed copper tuning slide for it, to give a warmer more flexible response. We're planning on having it all silver-plated when finished.

Why is the tuning slide not in brass also?
The tuning slide was hand made by me from seamed copper. It's a slightly more gradual taper than a normal trombone tuning slide (remember this instrument is twice as long as a bass trombone), so it was necessary to make a custom crook. Since I was making one from scratch, I asked Noah if he wanted it to be copper and he said yes.

By the way, the reason I'm holding it weird in the picture is because it's not soldered together yet, so I was trying to keep it from falling apart while I verified the pitch is correct!

Post by: sfboner on Aug 15, 2016, 11:03PM
By tuning slide, do you mean the J-bend?  Because it looks like the tuning slide is in the handslide (a genius idea for more than one reason!!) and is cylindrical.  Or maybe I'm just confused.

No, the tuning slide is in the smaller of the 2 loops in the bell section. (The valve wrap has not been made yet; the smaller loop you see is not the valve wrap; it is part of the main BBb horn.) The crook at the top of the handslide does not move.

I think you've muddled up the causal relationship there.  They have a low opinion of trombonists because they marry them.

I have a new idea for a contra: design the bell section with three valves and a screw-on leadpipe.  Then produce a valve alternative for the handslide and you have the ultimate doublers tool for unusual low brass parts: a contra, cimbasso, euphonium.

I get the cimbasso and contra part, but how could you possibly get a euph out of that equation? No matter what you put onto the bell section, it will be in BBb. Unless, that is, you were to shorten the bell section significantly (meaning the contra slide had to be way longer) so that one could simply attach a short tube and keep the horn in (tenor) Bb. However, this instrument would be ridiculously unbalanced/back-heavy and the valve tubing in the bell section would be twice as long as needed for a Bb euphonium. So once again, how would you get a euphonium out of it?

Rework the bell section with three standard valves, or four, don't use the slide, stick a mouthpiece lead pipe where the slide usually goes, and it might come out close to Bb.

If your thing worked for all of them, it would probably be really bad at all of them.

Those paddle-ends look absolutely identical to the paddle-ends on my independent converted Holton 169 - really just the same; same-looking metal, same shapes, same curves. I'm told that the conversion work on my trombone was done by Burt Herrick in 1969. Just a coincidence, or is there a connection?

Your valve levers were modified under Bob Weller's ownership. That might help.

Those paddle-ends look absolutely identical to the paddle-ends on my independent converted Holton 169 - really just the same; same-looking metal, same shapes, same curves. I'm told that the conversion work on my trombone was done by Burt Herrick in 1969. Just a coincidence, or is there a connection?
I model my valve paddles after the way Larry Minick did his, so that's probably the common connection.

Here is a quick video Brad captured today of our good shop pal, (and tubist extrodinaire) Blake Cooper, demonstrating the BBb contra low register. As you can see, "farty sizzle" is a specialty of this particular instrument  :evil:

"farty sizzle"

I will certainly continue to keep my eyes open, but I've yet to find a chart marked with performance instruction.  :evil:

Got the instrument back from silver-plating! Final assembly this week and she'll be ready for the front lines  :amazed:

Holy cannoli, that is one gorgeous contra. The slanted braces on the valve tubing look really slick. I look forward to the day that I can make one of my dream horns a reality, just like you've done here.

well, it's been about a year since we started this project and I'm happy to say that the instrument is finally completed! A real beauty too! So much fun to play. Brad did an amazing job, stunning work and design. I couldn't be happier with how it all turned out.

I'll have this contra at ITF in Redlands this year at my Brass Ark booth, so feel free to stop by, take a photo and have a blow on it!

Without further delay, final photos:

Shoot, I need to book a flight to Redlands. :-0

I've been following this project quietly since you first started it. What an absolute work of art it turned out to be. Kudos to Mr. Close on his stunning work!

Beautiful horn. But I have to ask: why the double slide? I thought that was the kiss of death with contras last.

Wanted to do this one in BBb, and that means double slide (or really long arm extensions  :pant:)

Actually, the slide action turned out to be quite good on this horn!

An army surplus missile launcher case might do. Might be hard to travel with on an airplane though.

Jeff Reynolds actually had his minick BBb contra in a surplus bazooka case, no joke!

This one actually just fits in a large Cronkite double case with the divider removed in the slide pouch and the long tuning slide removed.

I got to hear the Contra played in an ensemble today at the ITA festival. Benn Hansson played it on the bottom part in an all bass trombone ensemble. Benn did an amazing job, and he only had about a day to get used to the beast!

I'm afraid it pretty much consumed his life for a little while. He was using a corner of my exhibit room to practice.
