Pneumatic Idea

[mo_]

Howdy folks,

I have been along time lurker in this specific forum (I should be fine as long as my manager doesn't catch me ) and decided to contribute an idea I have been wanting to test.

At most bike shops there are tire inflation system that uses a small CO2 cartridge that are 2-3 inches in length. One could use this as an air tank in a pneumatic system (a depleted cartridge as the new ones hold up to 800psi which I am sure would destroy Lego). The only reason I suggest this is due to the small form factor (can be hidden in the chassis of a moc etc.) not as costly as buying an official Lego airtank.

I have not personally tried this (I intend to) on a system but if anyone is willing to try it would be nice to hear about your results.

Now I know this does not follow the guidelines of 100% Lego but in my opinion the metallic spent airtank might look pretty cool on the back of say the unimog.

Please note this suggestion is about incorporating the empty cartridge as part of the system.

Thanks for reading

@ mo_: Welcome to Eurobricks! I am not a "Lego purist", so I like the idea of utilizing a spent metal CO₂ cartridge. If there is a way of REGULATING the pressure (like the speed control knob on a Paintball gun), then a FULL CO₂ threaded cartridge could possibly be used on a Lego vehicle. The spent cartridges look a bit like full-size Oxygen or Acetylene tanks....

Thank you DLuders,

There are small regulators (I did the research a while back I recall something about a fish bowl and how the person adjusted the release so that it was so little that a bubble would appear every five minutes or so - each cartridge lasted a month or so) that screw on to the cartridge however at 800psi you would need to be very careful as to how much you apply to the system this is an untested theory after all.

i'd bypass the treaded valve and pop a couple of new lego-size holes, instead. if the walls are thick enough, you might even be able to tap the holes. it's volume is a lot less than that of the lego tank, so you'd need a good compressor to compensate.

Your idea is worthy of posting on CUUSOO. Here's the EB thread about how to sign up and use it.

I like your idea.

Here are my thoughts on the matter:

For the same purpose, couldn't you use an extra pneumatic piston, and connect just one of its outlets to the pneumatic system? ( Kind of like their use in lego pressure regulators)

Also, afak you could just use longer than needed pneumatic hoses for the sake of expanding the volume of your pneumatic system. Their internal volume could also work as an "air tank".

I haven't tried either of those ideas, but i think they have been used already in some mocs?
