I have a 1925 Curtis Air Compressor and we are rebuilding it to be a working show piece. The General Electric Motor is  running the Curtis Compressor, and we need the manual of the motor/compressor/tank or all of the Information about it that we can get ahold of so it can be rebuilt  to the exact color, wiring , ect, so we can put it back to its' original  origin.

Air ride bicycle suspension

So i've been interested in pneumatis for quite some time and recently I came across a small air cylinder (6 inch travel), 12 volt air compressor, 12 volt valve, and misc fittings. I got really excited and without thinking twice I grabbed tools and started hacking up my old beach cruiser (it was quite a mess anyway after 3 trips to burningman). So this is the outcome... I can control the up/down with a momentary on switch out back. Now just looking at this mess its easy to see that well i obviously can't weld. Never tried... Anyway it rides really sloppy as you can imagine, much like an old Lincoln with the shocks blown out, but it is so much fun! Now i pose the question to you community members, how would you have done this different? Looking forward to your responses!

Spring powered internal air compressor

Hello everyone, I've come here for some help on designing a PVC-based air tank. I'm planning on building a pneumatic cannon that I can charge once and use to fire multiple short bursts of air. To do I decided to have two tanks -one large tank acting as the main tank and a local tank with a much smaller volume fed by the main. My problem is that I want to squeeze out all the air I can from the main tank, and I'm not entirely sure what the best way to do that would be. My current design uses a spring behind a wooden plunger so that as the volume of compressed air drops, the spring can extend and restore the pressure. (Image attached for clarity) Can anyone spot potential problem areas or places that could be improved?

Wooden Air Cooled Water Chiller?

Does anyone have or know where to find plans for larger sized air cooled water chillers, such as those that used to be next to ice plants.  The vertical towers had water dropping through wooden, slanted slats which created chaotic air flow through the water, removing heat and chilling the return water.  Essentially speaking, I want to build a tower that can be used to chill large aquaria within outbuildings where fingerling trout are being raised.

Would a water/air powered CNC machine be feasible?

I was wondering if a water/air powered CNC machine would be feasible. Such a power method would allow the device to be powered by an outside compressor or pump or something else that supplies a flowing (pun) source of air/water. This would allow the only parts needed to be inside the CNC machine to be made by a CNC or small electricaly driven control valves and maybe some potentiometers for position sensing. I have noticed that most of the CNC plans that I see use stepper motors which if I understand right offer only 1 speed, but I do not really understand why. Please tell me what you think. I have been looking at these "build your own CNC printer" and "build your own CNC mill" sites alot lately, but I have no clue yet when it comes to such things.

How clouds act as an air pump to suck in air. Not how you think they do!

I have been thinking a long time about the biotic pump theory but I still don't understand it.  The math is too hard for me.   BUT it got me to thinking.   It is a point of major dispute in the meteorological world.   Does condensation cause low pressure?  2 russian nuclear physicists say yes,  almost everyone else says no!   So,  I thought and thought and thought.  Now I think I have a simple enough explanation And yes, they may not necessarily cause low pressure under the cloud (probably do)  but they definitely suck in air from elsewhere.  Imagine a fleet of huge doughnut shaped dirigible airships. They are sitting at 10,000 ft just floating there.   Now the commander tells everyone that they must now fly at 5000 ft.   So they turn on their propellers (in the hole in the doughnut) and drop down to 5000 ft by propelling air up  through the hole.   Now staying at 5000 ft is achieved by running the propellers at just fast enough.  So at 5000 ft they are pumping air from under the doughnuts to above them.   Now imagine a cumulus cloud.  Even though it is not fixed in size or shape and it does not have a propeller,  it is doing the exact same thing.  Air is being pumped up the middle and the clouds are sitting lower in the sky than they "should",  because they are sending that column of air up into the sky.   Here is my video to explain it visually.  https://www.youtube.com/watch?v=sPO8dWm_GIg

Amatuer experiment Contest! How high can an aquarium airpump pump water? Mini airlift pump.

I believe that many bubble pumps for aquariums can bubble the air about 2ft deep under water.  So if you use the air bubbler as part of an airlift pump, how high can you pump?  Here is a link about airlift pumps http://www.animatedsoftware.com/pumpglos/air_lift.htm (unfortunately the wikipedia airlift pump entry is commercial spam). Anyway, the aquarium air pump I used produces about 2 liters of air per minute (so not so much). So here are the contest rules.  Your airlift pump has maximum submergence of 2 ft.  You must use a T-Joint to introduce the air and you use an appropriate pipe diameter to airlift the water higher. The height pumped is measured from the top of the water in the water reservoir to the top of the airlift pipe and the submergence is measured from the top of the water in the water reservoir to where air enters the T-Joint. So, winner and Instructables world record holder is  the person who pumps water highest under these conditions. I will start with my example. Thats pretty much as high as I will go but if you have a suitable area, I think you might beat me! Competition is ongoing. Best of luck Brian

They range from $200 to $3,000 depending on the size and air current speed. I can visualize a wood box with the aperture on it for the air to come out but the insides would be a bit hard to find under $200. Maybe one of those standing fans?

Pedal-powered airship gets half way...

A French amateur pilot's attempt to be the first to cross the channel on a pedal-propelled airship has failed.Stephane Rousson, 39, from Nice, took off from Hythe on the Kent coast at about 0800 BST and was half-way to the French coast by 1300 BST.But he was hampered by a change in the wind direction and called off the trip 11 miles from Wissant in France.Mr Rousson said: "I'm not disappointed. I feel happy because it had nothing to do with any technical failure."During the challenge, Mr Rousson was suspended underneath the balloon envelope in a carbon fibre gondola, powering the two propellers with his feet using a bicycle-like contraption. The most amusing thing about the whole trip is the safety system:Just in case Rousson found himself flying irretrievably high, he hung an open penknife from the gondola framework, with the intention of popping the balloon and heading for a splashdown.Sorry, that's the second most amusing thing. The most amusing thing is the pilot's childhood inspiration - ET.BBC article
