Geoff, you are kinder than me. Id have suspended him for that and then refered it to the FRA governing body, where he could have apealed.

Anthony: How do you mean sort the compressor out ? The compressor works fine.

Having said about whats wrong with the air compressor, Ill tell you whats up with it, it east battery power nlike theree no tomorrow!

Hence the reason I am posting back here:

I need to know what I need for a good pneumatic system without making it complicated.

I already have the 2 air motors, but I need them CO2 powered, and also, to save gas, I need them to fire on both rams and return on 1.

I seem to recall Gordon (Stiff Breeze) saying I need a new valve because the one I have is, I think, a 5/2 valve where I need a 5:3 so it has a fire, retract and a neutral position

The reason the compressor eats power is because the cheap batterydrill like motor is asked to deliver torque to get the thing up to pressure, and that needs amps.Using a bigger reduction gearing to the crankshaft, or a motor with a higher torque (bigger motor, I advocate the Graupner speed 900, but other options are possible)

Do you have a pressure switch installed? Or do you just vent the overpressure with the prd?

To mount a low pressure CO2 system, I can say, use the Trevor regulator(change the CO2 nut to fit on a Paintball bottle) a 9 oz paintball bottle and a small buffertank. Then youll need the high and low pressure PRD to get to the rules.

On valves, the 5/2 valve can work your air motors fine, but yes, a 5/3 has the advantage of pre venting the rotacs, and that does have a sleight advantage on torque and speed.

Where would I get suitable valves/bottles ?

Valves, I can have a look in my meager leftovers in the Low pressure cardboard box.

Bottles/tanks, your friendly neighborhood paintball shop. (for me just around the corner)

Fire and return on both .....but use a lower pressure on the return might be a better option IF you need to save on gas consumption.
Your new co2 powered system may well negate the need for any gas saving.
What is the swept volume of your actuators?

As far as I know the setup, the return will take as much power as the attackstroke, otherwise the risk of not returning is not unimaginable.

In fact it may even need more as the axe may end up below the horizontal. But I agree with Woody and Mario, best to regulate down than only use one actuator for the return.

Hi Guys

I started on my robots repairs and upgrades, only to find my chassis is starting to twist and the welds are breaking (thank you Stiff Breeze!), and I was wondering if anyone has suggestions for a new chassis type, as the current one cant handle it (3 peices of 3mm Aluminium plate welded together).

For those who dont know, Hells angels armour is mounted 10mm away from the internal walls by foam, and I was hoping to keep it similer
