[pianotech] pneumatic soundboard press?

[jiimialeggio]

I'm upgrading my rib press.

A couple of questions:

1-I had a discussion with Bruce Clark a while ago regarding the stopping 
the hose ends. His suggestion  was folded rather than plugged ends, as 
the plugged ends can turn into projectiles.  I like this approach as it 
seems to be simple, safe and cheap. It requires an air fitting though 
that attaches through the wall of the hose (other than a schradrer 
valve), but I can't remember what that fitting was. Anybody have a lead 
on what this through the hose wall fitting might be?

2-There are various choices of hose material. What material has been 
appropriate?

3-In use, does the  hose have a tendency to squirm around as its  
filled...seems like it would.  If so how do you control it. Seems like 
the ends of the hose have to be allowed to slide as the air is applied.

4-hose pressure from what I read is 45ish.Correct?
