hose for belly press

[erwinspiano at aol.com]

  Hey Will
  I use  actual fire hose  & I can find it at the local Delta rubber supply. Very rugged stuff. I've pressed up 60 or so boards over the last 8 years & never replaced one.
   My set up does not leak at the clamps. I leave mine aired up sometime over night. The only place I get a bit of leakage is where my small connector hoses connect to the adjacent caul at the brass fittings. My entire rig is attached to the entire air supply during the process. This set up avoids the possibility of a hose leak down after Elvis leaves the building for the night.

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, hop
efully 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
