    Anybody here know about pneumatics?

    I'm outfitting a bicycle with an air horn and I have a few questions. I will be using a semi truck horn which needs about 100 psi to operate. I saw a similar set up that used an approximately 1 gallon CO2 tank was filled to about 150 psi with regular old compressed air. The guy said he could get three blasts out of it. Here are my questions:

    Where can I get a cable actuated valve? I will be using a brake lever to honk it.

    Is it possible/practical to use multiple tanks? I would like to use a pair of 10 oz paintball canisters and one 20 oz. How well do you think this system would work filled to aprox 150 psi? Would they be enough?

    If the above doesn't work, would it be possible to use CO2? I'm wondering how well it would work to use one 20 oz filled to 2000 psi or whatever they're rated for.

    Am I gonna asplode?

    PS: don't suggest an air zound. I want a big ass semi truck air horn and anything less will be unsatisfactory.

    Yeah, I'll probably get one of those at some point too, but for this application if it's not 2 1/2 feet long I don't wanna hear about it.

    ahh what you want to do mate is get your hands on a nitro tank problem with C02 its not very coaperative with weather conditions 3000PSI should hold you out plenty and its less problematic.
    a lanyard valve is what you should look for its the only thing i can think of that would work and for god sakes get a really good regulator a paintball one even though theyre pricy they can deal with the psi better and its smaller.

    Cable actuated valves are available at any Kenworth or Freightliner dealer.

    Cool, thanks for the tip on the paintball regulator. I figured a lot of the stuff for this project would end up being paintball stuff ($$$ ). Tell me more about the problems with co2... Isn't nitrous oxide more expensive?

    The regulators that come with the tanks I've been seeing are 800 psi which I'm guessing will be too much. Are there any nitrous tanks that don't come with a regulator or come with a lower pressure/adjustable regulator?

    This ain't for the TDF. It's going on a 40lb bike so I'm really not worried about it.

    youre gonna have to its a lot lighter and more compact, i got most of my stuff off paintball forums for far less than what they sell for new the only thing i bought new was the tank. Co2 puts more strain in the parts and when the weather is cold it tends to liquify and freeze up the valve or possibly ruin the diaphram on the horns. Nitrogen not really for 3000 psi worth its like 6 bucks around here

    If kemmer says he has a good reason, seeing the results will be a lot of fun.

    Anyone else expecting this thread to be of phantomcow's doing?

    I don't have any idea about this kind of thing, but I demand photographs of the finished product, and a description of how it was done.

    Someday I need to get back on my drill-battery-powered car horn project...

    I thought about that, but train horns have three or more horns and require more air than I am willing to store on this particular bike. Maybe on a trike someday.

    Remember, these horns are very directional.

    AH! The plot thickens!

    By manifolding the bottles together, you will get more storage volume, so you will hold your pressure longer. Hence, more blasts.
