Hi, anyone got any experience with Air Pneumatics ?? to switch points. I was just looking to experiment with a 25lt portable air tank & a few air valves/switches & some spring return cylinders. The cylinders i was looking at only take a 4mmOD pipe & wasn't sure what length of pipe i could get away with. IE: one of my points is 28 met away.
What i am hopping is to operate the points with just a singe air line with a spring return cylinder. It will save running electrics as this could be done at a central point with the air valves.
 
I use the SVRR Clippard based system on my line. Available in the UK from Anything Narrow Gauge. The piping they use has a 1.6mm/1/16" inner diameter. Run length of piping does not seem to be restricted. The main thing is the system is kept airtight, so it maintains its nominal pressurisation. With the SVRR system this is 30 psi. I only need a small compressor, with a 2ltr receiver tank (like one to operate a small airbrush) to operate mine. You could even use an old car tyre. Topping up is only required when opening a valve to admit/release air from a connected piston to actuate it, so not much. I even power my signals with this, it is very easy to interconnect various devices so they can work in unison.

I started electric, found that unreliable, went manual, found it tiresome, the went fully pneumatic - total reliability, lots of play value ! Max.
