[SML] Air bladder system for pushing down casters....

[Jon Ares]

So this is still a dream of mine, perhaps.... according to my files, I
queried the SML about air caster/diaphragm technologies, for wagon
brakes. (An air bladder, pushing down on casters, thus lifting the
platform, and allowing it to roll.). Michael Powers gave me great info
on systems he'd built, but it all seems like a ton of work, with lots
of trial-and-error.  (I'm always short on time, not a lot of time for
extensive lab testing.) :)

Has anyone tried building a system using something like these,
commonly available today?

My thought was replacing the tubing and valve with appropriate air
fittings, but also not sure if there's a two-way fitting that allows
inflation and deflation all at one junction.

Or other methods to quickly, quietly, secure rolling wagon units
onstage? I despise "wagon brakes" - the hold-down clamps repurposed
into "brakes." I do have a 4-brake pneumatic system that can work, but
it's a bit noisy (the loud PSSST! when releasing them) - plus, I'd
need many more than 4, which means getting more stuff, and if I need
to get more stuff, I might as well look at other options...? Leading
me back to the air bladder option, where air pushes down on a plated
caster, thus lifting up the platform and allowing it to roll.

Open to suggestions.
