Pneumatic questions, sorry!

don't listen to them, 6kg is a ridiculous amount for a fw ram. an aluminium ram that can take 10 bar will work just as good as a steel one.

Sounds fairy conclusive! Do most people have cushioning on there rams or not, the pneumatic guy said it was needed to stop the ram ripping itself apart- but now I don't trust him so much!

Cushioning is .. IMO .. a good idea.

Depends Woody. The Gravity/Cutlet system doesn't need it, the dampening is done on the heavy moving mass, the arm, what is mechanicaly seperate from the piston.

But for a classic setup -Chaos II-, it is mandatory.

But it adds size to the ram. A lot of it.

Of course it depends.

However the question appears to be about a standard pneumatic ram ( double acting ) mechanically attached to the bot base and flipper arm... rather than a single acting F.P. ram with the flipper arm free to move and restrained/damped by bungee cord.

Hence ..

Cushioning is .. IMO .. a good idea.

IF Max has access to machining facilities and feels competent it may pay him to remove the return / base cushioning and thus shorten the ram.

I know I have asked before but I got 2 answers so I dint know which is correct. What length is a 20oz paintball bottle? Is it 330mm long or 238mm long?

**maddox10** · 23rd January 2012, 20:15

I messured mine 20 seconds ago.

The bottle itself is 260mm long, with the on/off valve mounted, 295mm. Diameter 84mm

Remember to add on something extra for the fitting that will screw on to the bottle.

I just received my paintball bottle and the on/off valve. Do I just put some molegrips on the old pin valve and wind it off and then screw on the new one or is loctite/araldite necessary?

Also I can't screw my Trevor regulator onto my on/off valve! When I try to screw it in the thread on the valve can't reach the thread on the regulator, do other people have this problem?

Remove with grips and I use a drop of sealing compound. when screwing in the new valve.

The Trevor regulator isn't supposed to fit a paintball valve ...the threads are different between a paintball and European CO2 cylinder.
