How long is a 2nd valve slide on a F horn?
A 2nd valve slide on a F horn is 8-1/2 inches, a stopping valve slide on a Bb horn is 8-13/16ths. That is in closed position, for tuning purposes I find I pull my stop slide out another full inch of tubing length.
Which side of the triple horn does the stop valve go on?
Relating to both of the comments above, on the horn in the photo with this post the stop valve can be used on the F or B-flat sides of the horn, depending on how you set up the horn. I find that in reality the stop valve needs to be just a bit longer than the second valve slide of the F horn to give the best stopped note intonation and at at that point it is equally in tune on either side of the double horn part of the triple. (The high F side not having any stop valve on this horn).
Do double horns have stopping valves?
Many double horns F/Bb) have stopping valves on them as well. For horns like these do you only use the stopping valve when stopping on the Bb side of a double horn?
How far can you pull a slide?
If your hands are small and raise the pitch more than a half step you can pull the slide as far as needed to get things to line up perfectly.
Can you use a second slide on a F horn?
Yes, you could probably use a F horn 2nd slide, but you would have to pull it out much further than normal. More so there is a mathematical relationship here specific to each Horn wether it be in F, Bb, C, A, or D. Technically, to the extreme, to use the stop valve correctly you should reset the valve slides because as you lengthen the horn by adding the stopped tubing you need to lengthen the valve slides to be compatible. (That's an extreme technical thing - not realistic in the real world of horn playing unless the whole piece is stopped horn). But if you use an auxilliary valve to go between keys, you do need to reset your valve slides to be correctly in tune.
Can you use 1/2 step tubing on a Bb horn?
YES It is a great invention BUT - I don't think you should use "1/2 step" tubing here as it can be misleading. Stopping on a Bb horn raises the pitch more than a half step. Adding a half step in F would not compensate enough. A 2nd valve slide on a F horn is 8-1/2 inches, a stopping valve slide on a Bb horn is 8-13/16ths. That is in closed position, for tuning purposes I find I pull my stop slide out another full inch of tubing length.
