Slide had fallen

Postby guillaumedu » Wed May 17, 2017 10:43 am

Hello
I bought used Nirschl handmade. The 1st 3rd and 4th valve slide goes very well and i like it that way. IT's really Easy to make adjustment. But in 2 month they had fallen 2 or 3 Time each.

What système do You used ? Pictures please.

Some people tie shoelaces or other strings around the slide and the nearest brace. The MW Baer tuba has a fancy version of the same thing.

Here's a picture from someone's for sale ad:

I have a similar problem with the first slide on my PCK if I don't push it in all of the way before setting it down. The above picture is what I plan to have done if it becomes more of an issue.

You could also get a stop-rod installed, for a more finished appearance. My old Miraphone 188 had something like that on the 1st valve slide, which I think was made out of Bach trumpet parts.

Just make sure that, like on a Bach trumpet, that if a stop rod is installed it is "double nutted" so the nut doesn't work loose, fall off itself, and defeat the purpose.

Thread the rod to the closest metric thread to the SAE thread of the Bach stop nuts...then "muscle" on one or two Bach stop nuts. Put a really small-ring in front of the stop nuts, to prevent a banging noise (if you pull the slide all the way to the end of the range).
