Pneumatics for my axe

Care to list the pneumatic component weights Dan ?

Ram , Buffer , co2 bottle , pressure regulator , Axe and mech ,suitable 5/2 pneumatic valve ... sundry pipework and fittings.

Ultimately its your choice and if your happy go for it.

Ram-about 1.5kg?
Co2 bottle-500g
Buffer-1kg for both
Regulator-I dont know
Axe and mech-2.5kg
Valve-450g
Battery-400g
Motors-1kg
Speedos-150g?

Total:Around 7.5kg

So that gives me about 5-6kg for chassis and armour.

Which i am sacraficing for the Axe.

So 5mm to 7mm polycarb.

Some of my calcs might be a bit out,but thats around about right.

Thanks.

The SMC CG1 Ram you linked to further up the thread appears to weigh in at around 3.5 kgs.

No im using a different ram,but that was just a geusstimate weight for it.

But even if it does weigh 3.5kg,i still should be ok.

Do you think I will need one or two buffers?

[woody]

Just the one buffer tank should be fine.

Ok,Mario said i should have two,otherwise I would only get about 20 hits.

Thanks Woody.

The quantity of liquid co2 in your main tank dictates the number of available shots.

I said that the volume of the Buffertank should be 3 times the volume of the ram, or more.
Less, and youll use up more weight for less advantage.

My take on a buffer tank volume....

Twice the rams volume is acceptable ...three times the rams volume is good.... but anything is better than nothing.

Powder extinguisher bottles etc make light l.p. buffer tanks just check the pressure rating before using.

Ok,I think to start I will have only one 12oz buffer,and a 12oz main.

Is that good?Or should I have a bigger main?

[woody]

12oz liquid co2 = approx 18 litres of gas @ 10bar.

A 12oz tank has a volume of around 0.5 litre.

Is it enough ....dunno.

Your ram volume is?

[Guest]

Im not sure what my ram volume is.

I havnt got it yet.

80 x 80 ram = 400cc

Ok,so what kind of thickness on my axe head would i need to stand up to the power?

What material do you think would be best?

Thanks.
