Hi,
I have recently developed a pneumatic gizmo to remotely act on my train
track points, which is working quite nicely. The thing is, I don't know *how
far apart* can I place the compressor so that the loss of charge in the
tubes isn't too big. Has anyone tested this?
And another question, related: to remotely act on the points, I need to have
the pneu-switches *far* from the points (doh!). But by doing that, instead
of having one *long* tube from the compressor to the pneu-switch, I'll have
two from the pneu-switch to the pneumatic cylinder. Does that mean the
design will work less efficiently, or is the difference neglectible?
TIA,
Pedro

| (...) From my experience, you can have really long tubes (10~20 feet, or more) and not have significant losses due to friction. What you should be concerned with is the volume of the tubes. Basically, if you have a lot of long tubes, your system (...) (22 years ago, 6-Sep-02, to lugnet.technic)

| It's a pity there isn't a remote-control pneumatic switch you could connect up to Mindstorms or a similar system. I would *love* to be able to remotely control switches, this would solve your problem somewhat by drastically cutting (figuratively (...) (22 years ago, 7-Sep-02, to lugnet.technic)
