hose for belly press

[Will Truitt]

To the bellymen on Pianotech Forum:

 

I have built a set of cauls for gluing ribs to the panel using air pressure.
I discovered yesterday that the 1 ½” rubber hose that I bought from Home
Depot is most decidedly not ready for prime time – no matter how much I
tighten the hose clamps on the hose at the ends, air still bleeds out at an
alarming rate (easy to see when you inflate the hose and stick the end into
a pail of water).  After discussion by phone yesterday with Jude Reveley, I
am confident that the material is inadequate.  Pressure ratings aside, it
simply is not substantial enough to resist the air pressure.  

 

Jude has recommended a ribbed nitrile/PVC hose, which is what he is using in
his setup with good success.  I am looking for a source for such that I can
quickly order it online, hopefully in smaller quantities.  

 

I would also consider other hose materials that our bellymen are using with
good success and reliability.  

 

Thanks in advance for anything you share
