Fine here.

Looks good here.

I must admit to liking the music of Earl Scruggs and The Foggy Mountain Boys.

I did notice this when I blew a few notes on a 1941 York Custom that I had not played for some time, thinking I do not remember it being this bad I put it down intending to investigate later. Mystery solved.

This morning I played my1931 King Silver Tone trumpet for the first time in over 12months, the valves were free and smooth, I did not oil them (shame) and found as Dale the tone was dull and lifeless, after about 10 minutes of playing the tone was much improved and sounded more like me. I will try it again tomorrow after playing my usual horns.

I have not noticed this on any of my other horns that get played on a regular basis.

Regards,Stuart.

Before I play a horn I will oil the valves, one drop in each. Calculating the volume of the space between the valve and casing at around 1/50 millilitre, one drop about 1/30 mill plenty enough. On a long gig of 4 45 minute sets I will re oil at the second break. Never have valve problems. Regards, Stuart.

Without good provenance it is just another pretty Selmer Balanced Grand Prix.

Would be interested in seeing a Barrel backbore, when lockdown lifts and I am able to visit the shop if they have some.

This afternoon I checked the backbore of 20 mouthpieces across 7 manufacturers using a No 30 drill rod, all were a straight V. If there is an advantage I will make a profile reamer and alter a couple.

Has anyone experienced the Xstreme mouthpiece made by John Eth with the "Power Chamber."

Regards, Stuart.

Excuse my ignorance but what is a "Barrel:mouthpiece"? in 35 years of playing I never come across this term until this post nor have I seen it in any mouthpiece manufactures literature.

regards, Stuart.

I have been doing my own visual alignments for some years, I use a No 0 dental mirror ($4) and a single led Book light ($2), the second thing I do on a secondhand horn after a good cleaning.

2 examples come to mind, a Bach 1964 Mt Vernon Large bore purchased from a local shop on consignment from the estate of the original owner, it had been serviced by the shop, cleaned and new felts fitted.On getting it home I did not feel it lived up to the hype the Mt Vernons receive. Checking the valve alignment all valves werre out in the up position, rectifing this made a great player, all my friends that have tried it want it.

Purchased a 1941 York Custom from an on line dealer I had several transactions with, it arrived with a note saying "I hope you are happy with it, it does not play very well", this was an understatement, there was no note center at all! The valves were a long way out of alignment, rectifyng made it playable but I was not happy with it, the notes now centered but the tone was dull and lifeless, it had at one stage had the leadpipe bent and straightened not very well, the rear brace resoldered with an excess of solder, on heating up to remove the excess solder the brace let go with a loud pop as the tension was released, plays much better now.

One of these days I will dismantle the whole horn and reassemble stress free.

Valve alignment in most cases is a compromise, I have measured the difference in the spacing of the input and output ports of valves and found only 4 trumpets that I feel are within good engineering tolerance 0.002", coincidently they are my best players, 1949 Olds Super Recording Eclipse and Taylor with Bauerfine valves and 2020 Jerome Wiss 6/20.

@J-Jericho said in No Name Trumpet:

I have not played this trumpet; my friend lives in another state.

The blow dart gun looks like an interchangeable leadpipe insert. See the clamp screw on the mouthpiece end of the leadpipe on the horn?

What do you make of the collar connecting the bell tail to the piece of tubing coming out of the first valve?

Judging by the knurled collars in the middle of the front and rear bracts and the brace from bell to 2nd valve the bell is removable.

The Wiss may look like a compensating instrument but it is far from one, the Wiss valve has only 2 internal passages, one strait through and the other a loop, with the valve up the wave goes through the loop one way, down goes through the loop in the opposite direction.

The interconnecting tubes between the valves are outside the block

Regards, Stuart.

The 3 valve trumpet plays on the natural harmonic series of 7 different lengths of tubing which gives a reasonable approximation to a chromatic scale,.

When we play in a group we aim to play with just intonation where the chords are in tune.

Playing with a piano or electronic keyboard we have to match equal temperament.

The appendix to Boosey and Hawkes Compensating System reffered to in the thread "Third Valve" shows the differences,

Boosey and Hawkes Compensating System gives an excellent description of the theory of why 3 valve instruments need extended slides.

I can attest the Wiss is the most in tune trumpet I have, I have not had a chance to play it in a group as our Orchestra and Band have been shut down since mid March.

Well said Rowuk, here in Melbourne we are in stage 4 lockdown for the next 6 weeks due to second wave of infections, curfew from 8:00 pm to 5:00am, travel limited to 5 km from home, only 1 person allowed out at a time, businesses closed except essential. No group music since mid March. I doubt the community Orchestra I play in will resume this year. We have Police and Army Personal checking people that have been found positive to the virus are staying home, yesterday they found 150 not at home, What hope do we have for a fast recovery.

"The difference between one mouthpiece and another is about 3 weeks" Merv Simpson former Melbourne Symphony Orchestra.

We had 3 weeks when Big Band commenced practice with limited numbers (6) on a roster system then we went back into lockdown with no sign of .when we may resume. Orchestra is not likely to resume this year.

The balance is extremely good with the thumb and forefinger each side of the valve block under the bell. With Dupoitrans contraction in both hands I normally hold a conventional horn underneath the valve block, with this one I can use the conventional hold.

Notice there is no pinkie hook or water key, my hand condition does not allow use of a hook and having played French horn for many years I can manage without a water key.

At 2lb 7oz it is not a lightweight horn.
