88h bell thickness
Elkhart bells are thin. Gen2 bells can be labeled 88hT for thin. When did the bells start getting thicker? I'm not stuck on Elkharts, but I don't want a thick bell. I had one and don't want another. Might have to buy a horn without playing it first.

Re: 88h bell thickness
I think that the Elkhart bells were constructed out of two gauges (at least some of them), with a thicker gauge being used for the flare and a thinner one used for the throat. I think that the switch to thicker bells was pretty immediate with the UMI acquisition. The 1992 horn I had (not sure if that's a gen ii or not, it had an under-the-thumb string linkage) felt extremely thick and dead, but that could also be because of the thick lacquer.

Re: 88h bell thickness
The UMI GenII I had was bought in ~2003 and had the 8hT designation, so by that time they were at least labelling the thinner bells.

Re: 88h bell thickness
I've found that towards the end of the 60s the 8/88H bells got heavier/thicker.
At least what I've experienced thru purchases.

Re: 88h bell thickness
The first couple.of years of.producrion in Abilene featured similar thickness bells as those from Elkhart. It was during the "Artist Symphony" (as engraved on the bell) series that bells became slightly heavier, but the move to Eastlake really brought the heavy bells to become the norm. I believe it was in an attempt to try and keep up with, or at least try and recoup some of Bach's market share, that prompted the change.

Re: 88h bell thickness
During my time as bell maker for Rath trombones I looked into this as part of my research in to vintage instruments.
8H & 88H bells from the Elkhart period were the most consistent in gauge of all the models we had come through the shop. 6H's seemed to have the biggest variation although sadly, I didn't correlate that against any sort of time line ( far too busy).
My own personal conclusion was that the 8H /88H design was in part , like many early American instruments based on a European instrument , most likely German.
Many German instruments feature a very then bell ( quite often one piece) with a nickel silver Kranz covering the last section of the bell flare. My belief is that this design is used to give an easy responding instrument that is also able to handle higher volume levels with out breaking up.
The 8H/88H bells I believe try to replicate this idea in a two piece bell by using a very thin stem 0.3mm ish and a a flare that is approaching 0.8mm at the very edge / The flare gradually goes up in thickness from where it is brazed to the flare , although what process is used to achieve this with consistency at the volumes Conn were making these models I don't know.
I have made a few 'copies' of these bells during my time by hand thinning the flare with a sharpened blade, which did work but was quite time consuming and open to variation.
As to why the bells got thicker at the Artist Symphony stage? I would suspect because it was cheaper and could be more easily made by a less skilled workforce. Despite a lot of people on here's romantic notions about why things change usually it comes down to cost.........
As a last thought I and others observed that the very best playing 8H/88H bells seem to ring to either a G or F# and I found by partially annealing the bell where the flare was joined to the stem I could get most bells close to that pitch.
FWIW

Wow, thank you very much for that! My 68 88h rings at F#, a really nice player. Maybe I should just look for Elkharts.

Re: 88h bell thickness
Have you ever tried one of the Shires 2RVET7 bells? Might be worth checking out. Possibly grafting the bell on to a Conn 88. I have one that plays great. It isn't an Elkhart, which makes sense given the rest of the horn is (essentially) Shires. But on a horn that is otherwise Conn it might be a good fit. My understanding is the "VE" stems emulate what Bellend was talking about and the T7 treatment is the thicker flare that has been made slightly thinner. 2 means it has an unsoldered bell bead.

Re: 88h bell thickness
T7 is actually a smaller gauge bead wire than standard.
And yes, the classic Elkhart 8/88H bell is two-piece, with thinner sheet used for the stem and thicker for the flare. The Shires 2RVE and 2RVET7 are patterned closely on it, specifically on measurements Steve took from a 1963 8H he used to own that he considered to be the best example he had found.

Re: 88h bell thickness
MattK, Gabe,
I'm just not interested in Shires stuff. I had an experience that kind of put me off of them. I'm sure they are fine instruments, but I get a better result from less perfect equipment, if that makes any sense at all.
It is kind of fascinating to hear how stuff is made, though. The two thicknesses thing is really interesting. I tend to think of sheet metal as a single thickness, but the technique of brazing dissimilar thicknesses gives it an entirely new dimension, so to speak.

It rings a little in the way you describe and in my opinion plays great. The ringing is a small quirk, perhaps a minor inconvenience but I wouldn’t want to deaden the horn in any way to reduce it. Don’t suppose you were there at that time and remember looking at such a horn?

Hi,
I left around 2005 which feels like a long time ago now.
The 845 was an attempt to replicate the best of the Elkhart 8H/88H bells, not sure if they make those anymore the metal at that thickness for the stem was a special order from the rolling mill .

Nickel silver is a lot harder to work with than the other metals , it's not as pliable and work hardens much faster.
It's not for everyone but some people sound amazing on them like this guy 'Frosty' who was around the workshop a lot the time I was there.

That's some playing. Who was it recently that was saying a bass bone can't play walking bass lines? The video was a little out of sync with the audio, so I just listened. Thanks for the link. It was followed by a couple of euph players last name of Childs - some pretty monster playing there too.

The reference to the Childs family made me laugh as a former British brass bander, it’s sort of equivalent to saying “I saw a video of a trombonist called Joe A, he’s pretty decent”hyperbolica wrote: ↑Thu Oct 14, 2021 11:57 am That's some playing.

Equally I’m sure there are some top quality Polka/Böhmische tenorhornists who most brass musicians in the UK have not heard of or LA studio players whose names are completely foreign to those of us, myself included, outside of that world.

Ha, same here. For my money David Childs is the best euphonium player on the planet, and who I try to emulate. I attended a recital he gave at ITEC one year and it was unbelievable.

Re: 88h bell thickness
Hmmm... My 88H bell (with an early 70's prototype Ultra-thin rose bell from Conn (never lacquered from the factory) actually gives a hint of a ring on F#/C#, but this baby rings like a freakin' bell on E-natural, both in staff and low E. In-fact even thumping the bell flare sharply with the soft part of your finger while holding the horn normally in the air with the left hand makes it ring like crystal. But it is clearly an E-natural. I mean a perfectly in-tune E-Natural too.bellend wrote: ↑Thu Oct 14, 2021 4:12 am During my time as bell maker for Rath trombones I looked into this as part of my research in to vintage instruments.

I have no idea how or why, but I love it.
The bell was added in 1973, after some severe damage; but, the horn was never quite right really. Then later in 2000 I had the horn rebuilt by Dick Akright of Best Repair, Oakland. Tearing the horn down to its individual part and rebuilding it exactingly to Elkhart specs. He also built a completely new slide from new inners and outers too.
Here are photos of it when I got it back in late 2000.

Re: 88h bell thickness
PS: I know these replies are very late, but whatever. This is when I got here. lol
I really appreciate the info regarding the Elkhart bell construction method. Now it is clear why they are play so incredible when compared to the more modern versions. It is like a completely different instrument, and far inferior construction and design.
I am curious if what I have is an early HRT version. I heard this model of the newer line (HRT) actually plays similarly to the old Elkhart bells. In other words warm, broad, open and responsive in all registers.

Re: 88h bell thickness
I have an 1982 Abilene Artist Symphony 88H I bought new that I've posted about before. Graham Middleton rebuilt it for me with a new Instrument Innovations valve and new slide inners. His take on it was it had more in common with a Bach 42 than an Elkhart 88H--heavy bell, light slide. Whereas Elkhart's were just the opposite, thin bell, heavy outer slide tubes.

Re: 88h bell thickness
Thanks for these very interesting insights!!!
This might explain a bit why it's obvisiously not that easy to just copy those elkhart conns.
I have a doubt: I saw a horn offer staying Elkhart 88H "Artist symphony" from the later 60s. Does that make sense? Where there Artist symphony 88Hs built in Elkhart?
I understood from the posts above that there was a "Artist symphony" time whose bells where built of thicker Material and that it startet post-elkhart.
Could someone help which that?

It's the same model.
Elkhart is a City name, where "88H Artist Symphony" model was made before factory moved to Abilene.
And, when people say "Elkhart 88H" or "Abilene 88H" they're meaning exact period when trombone was made.
