    Featherweight flipper from scratch?

    Hi All,
    I`m about to start building a featherweight flipper from scratch, I`ve built a few robots before but pneumatics is completely new for me.
    I`ve already been advised to go for a paintball tank and I`ve seen some on ebay, I`m also planning on a 50mm bore 75mm stroke cylinder or thereabouts.
    What I really need to know is what other bits are the best to go for (as cheap as possible), ie regulator, valves and stuff? what adaptors will I need for the tank and for refilling too?

    I will be at Kidderminster too so hopefully I`ll get some info there as well.
    I will want to have it built ready for Memorabilia in November.

    Thanks
    John

    Where is this darn Wiki!!!!!!!!!!!!!!!!!!!!

    These are all very valid questions, and given the complexity and danger of Pneumatic systems I can understand why people would seek out guidance - a single source of concise information is desperately required!
    Plus I must have read every single Pneumatics related post on the forum and I'm just as clueless as before......

    EDIT: Sorry John, not very helpful for you......

      Let's start from the beginning.

      A paintball CO2 tank (do not buy HPA-compressed air tanks) comes in several dimensions. From 3.5oz ( 100 gram) to 20oz (600 gram).
      Adaptor and/or refill station. Any online paintball store can sell you those.

      Regulator. I believe there will be new Trevor s soon. Cheap (for a regulator) small, light and specific for RW. (use the search function)

      Valves. you need at least 3 valves. Main control valve (this does the work for the weaopnactivation) , pressure relieve valve (safety , to vent overpressure) in a LP system it could be you need 2 of'm, and a dump valve (in most cases this is a small ballvalve)

      Best bet is to search on Ebay. Because new pneumatics are expensive.

      Other solution is to get custom stuff.

        Thanks for your replies.
        How do I work out the volume of co2 from the bottle size? I don`t want to buy a bottle that will be too big.
        thanks again.

          Every kilo of CO2 is 512 liter of gas at 1 bar.
