length of 1st valve tubing on a F tuba?

[Michael Bush]

For my euphonium 5th valve project I need to add the length equivalent to a 1st valve on an F tuba. Does anybody happen to know how long that is, or will one measure for me?

I looked on Art Hovey's website, but I couldn't find what I was looking for

18"

Somewhere around here there is a post, possibly by Dan S., that lays out these lengths for every pitch of tuba. I copied the substance of it into another file on my computer and saved it. I looked this one up from there. But if you search around you can probably find that whole post. Or I guess I could copy it back into another post, but that seems like cluttering things up.

It was by Dan - I don't have the original post, but I copied the data from it - here it is:


F
1st valve = 18"
2nd valve = 8"
3rd valve = 27"
4th valve = 48"

Eb
1st valve = 20"
2nd valve = 9 1/2"
3rd valve = 29 1/2"
4th valve = 52"

CC
1st valve = 23.7"
2nd valve = 11.257"
3rd valve = 34.957"
4th valve = 61.62"

BBb
1st valve = 26.66"
2nd valve = 12.66"
3rd valve = 39.32"
4th valve = 69.32
