Re: Intonation of C Valve Trombones
For anyone interested, this morning I cut 5mm off the second valve slide and about 15mm off the first valve slide. Rough finished, reassembled, and a big smile! I figure this bone is mine for the long haul so I'm not worried about resale, and it is now very much in tune with itself. The third valve slide I'll leave as is. I read on another forum that Harry James used to set his third valve slide out a bit and just leave it there. This simple modification was just the trick and now I can adjust the slides properly.

Re: Intonation of C Valve Trombones
Curious if the OP still has the Packer valve trombone in C and, if so, how it’s held up over time. I’m considering this as well as the Jupiter 720 for myself.

Re: Intonation of C Valve Trombones
I still have it and for the price, it is a great horn. Originally, I could not get it in tune with itself as the length of the first and second valve circuits were each a bit too long. My impression was that it was designed as a Bb horn with the main slide cut to C and no consideration given to the valve circuits during manufacture. The above posts describe how I cut them myself. I don't mind the third circuit a bit longer as it is. Also, once I cleared out manufacturing debris (common to some new horns) the valves smoothed out nicely. My most important consideration is to have workable intonation in a smaller ensemble where you can really tell. I am not sure of the price of the Jupiter, but my question on researching each would be just that, are the valve circuits specifically designed for a C horn. Hope this helps!

Re: Intonation of C Valve Trombones
Very helpful. Thank you!
A new Jupiter is ~$1150, so a few hundred more than a new Packer. The parallel valve slide tubes are much closer together (like a trumpet), so it might be more difficult to cut them down (if necessary) without disassembly and then resoldering.
Did you use a plumbers’ pipe cutter to cut down the intact Packer slides?

Re: Intonation of C Valve Trombones
Everyone who really knows how to do this please excuse what you are about to see
I used one of these from Home Depot very slowly and carefully but you should not have to do this to a new horn, possibly Jupiter has addressed this in their design and manufacture

Re: Intonation of C Valve Trombones
And for my part, I promise not to reveal that you used JBWeld instead of solder to reassemble.
Seriously, I've been told by a tech that for cutting thin tubing he uses a jeweler's saw, which is basically a coping saw (rather than the hacksaw you posted) with an appropriate tooth pitch.
I would have reached for my Dremel but he said he gets better results with a saw.

Re: Intonation of C Valve Trombones
The access was crazy but I did not disassemble. There were times I removed the blade from the handle to work more slowly and with very little back and forth saw movement due to access. I was already out of my league, if disassembly were required I would have been even farther out and would have punted. Working without damaging adjacent surfaces was stressful!timothy42b wrote: ↑Tue Feb 23, 2021 10:19 am

Re: Intonation of C Valve Trombones
Looks like the Wessex C has shorter slides than the Bb, Johnathan would confirm that.

The Wessex French C could be an interesting alternative to a valve trombone.

Re: Intonation of C Valve Trombones
In the early days 18th century? There was something called a Parson's trombone, pitched in C, supposedly to assist in playing hymns without transposing. It never made a lot of sense to me but the reasoning seems to be about the same as yours.Worth wrote: ↑Wed May 29, 2019 7:24 pmIt's OK I probably didn't explain it well. I don't usually play a Bb instrument reading BC, so in that situation I am like you dealing with reading everything one step higher than usual (backwards to your deal). I can do it, but the mental exercise takes away from the enjoyment of it all. I came into the C Tuba world from TC trumpet via TC Euphonium, but as a piano player I read BC and TC fluently. This allows me just read the notes for what they are at concert pitch and just think of it all like left and right hands playing piano. The C Valve trombone therefore uses the similar fingerings as everything else keeping this beautifully flawed system working. Not ideal, but it is something I can wrap my head around and enjoy myself with less introduction of error, especially when sight reading.SteveP wrote:I don't understand how a player who usually plays a Bb instrument would find it easier to read the same music when playing a C instrument. If I were playing a C trombone (valve or slide) I'd be thinking about playing each note fingered (or slide position) one full step lower than usual. How is this effortless? What am I missing?

Re: Intonation of C Valve Trombones
Made for young players, but could have the rotor turned to make it a C bone, does anybody have experience with this one: YSL-350C?

Re: YSl-350C
There is an ongoing discussion about this horn and JinBao clones in the Instruments section of Trombone Chat.
Ascending valve to C, dual-bore, lightweight and very well made. I owned one and wish I hadn’t sold it. They aren’t very common in the US. Schiller and J Packer sell very similar horns. Possibly Thomann, though the bore spec is different - I suspect an error.
