I verified this for myself tonight with three pumps working three
airtanks and two cylinders and yes, one hose did come loose. Thanks for
the heads up! This did give me pause for thought though as I know have
to consider whether to build some sort of access control into my model
ideas in case a hose comes off deep within the recesses.

I'm pretty disappointed with the combined storage capacity of the three
tanks. Working together on only two cylinders from max pressure (I
presume... would be nice if there was some sort of meter) resulted in
only seven extensions and retractions. My hope is to link three to four
cylinders to a single control switch and I don't want to constantly be
pumping things up, especially if I don't have the room to hide or
disguise all three pumps I was using.

Gracias! Glad to see this!

Interesting! I would have thought that the hard tubes would not have
been able to provide a tight enough seal to keep the pressure from
escaping. I'll have to mess around with this...

Bummer! I'd like to check it out.

Indeed! Thank you very much!
