Help with lego compressor

[Burf2000]

Hi people, I have built a lego pneumatic engine based off some examples on youtube. However I am trying to build a compressor to run it, I had some very odd results (for me anyway)

I have been using the Lego RC motor. I first tried 2 little pistons which did drive it, then thought I would go to 4 to get more speed and it does not seem to move it. The went to using the really old pneumatics with the value block, this was kicking out major air, yet it does not move it. I am causing issues by trying to create more air?

Any ideas?

I believe you won't be able to run it from a compressor made out of LEGO.

Those we use to see, run form real compressors achieving higher pressures.

For a short run and, you may try to use a manual LEGO pneumatic pump.

Well I did do it from 2 small pumps running on the RC motor, just was not fast (and noisy), oh is this a first?

Trying to make something interesting for the UK STEAM event, want to do a whole technic mindstorm thing

I don't think you will have much luck with the current lego compressors as these engine take up vast amounts of air.

However if you don't want to spend hundreds on a real air compressor or don't want the noise, and you only want relatively short bursts, you might want to try moddifying one of those gardener planter sprayer thingys

You can get quite alot of pressure out of one of these

Lego compressors cannot provide enough air flow.

For best result use big compressor (for car tires), or alternately modify two Coke bottles, fill them with bicycle pump, and use valve to release the compressed air.

So the fact I done it, do you think that be a quite a cool thing to show at a show?

I think that in the context of a UK STEAM event you should either try to make your engine look and work as authentically as possible or build it into a model of a traction engine or an old fair ground ride or something. That would be quite a cool thing.

Well I have made a simple one work that has a see through piston so you can see it working. I was also going to put that in a traction engine but trying to think what would make a good boiler that has a diameter of a bout 2 inches
