Bellow-Bag connection - weird airtight solution!

Postby ugrash » Mon Jan 07, 2013 6:20 pm

Hello to ye all!

I got so anoyed that the connection between the bellow and the bag always was leaking.
Because you open and close it every time you play it fast lack it´s sealing power if using ordinary cord.
At least it was so for me. So I installed a hoseconnection for highpreassure instruments instead and now
it is completelly airtight and easy to connect every time I play.

I just wonder, is this against the "rules" or just verry smart? Is this something almost
everyone does or am I quite alone with this solution. Please give your thoughts.

Added is a pic so you get a better hang of it...

Don't know about the rules Pierre, but looks a pretty substantial way of eliminating potential leaks!

My concerns are the narrowness of the bore and the weight of the fitting... any noise as air passes through?

Hello and thanks for comment.

Sorry some errors in writing earlier post but I had my 4 year son Wilbur at
the computer and he picked on all buttons he could find. Amyway,

there is no leakage whatsoever and it is easy to put on an out you just have to
remember to deflate the bellow before you take it apart due to the backvalve.

The weight is of no concern I think, it is maximum 150g.

Finally about the narrowness of the bore, first I tried a 6mm nipple but then
it was hard to get air to the bag so I had to carefully redrill the woodenpart so I could
fit a 9mm nipple. Now it works fine and is easy to inflate. So conclussion is that
you´ll need a 9mm nipple at least.

I can not hear any noise when it passes.

If it´s any wrong in my spelling please forgive me, I´m from Sweden:)

The conventional connection - a blowpipe with an efficient leather valve and correctly bound at each end with beeswaxed thread - should work near-perfectly. Any deficiencies are usually caused by a bellows tube length which is incorrect for the individual player.

That said, the best arrangement is usually the one that you have confidence in, and the method illustrated seems very successful.
