as for retracting the cylinder I think there's another way, and you could do away with bungees and Co2.
If you plug the retract side of the ram, the trapped air will act like a spring and pushes the piston back again when Co2 press is released. Having said that I have not tried this on my machine as the weight of the flipper eliminates this need ...
That will give loss of stroke, speed and maybe an blown out endcap.Quote:

Wasn't satisfactionary. Bungee will do nicely.
And the weight of the arm doesn't do anything when the machine lays on the side.
yes a small buffer would be a good idea, but I fail to see the sharp pressure rise and risk of blowing an endcap.
I suppose that if you put 10bar on the extend side and blank the retract side at atmospheric press, the result would be that the piston will extend until the pressure on the blanked side balances at 10bar, the ram is built to withstand this pressure so I can't see the endcap being blown off :roll:
Loss of stroke and speed would be an issue tho :? Anyway I'm no expert and not having tried this out yet, I'd go by what maddox is telling you, Chris.
Ah, our machine is built in a way it won't stand on its side, it's either on its feet or on its back :wink:Quote:

Have a careful think about a pneumatic spike, the chances of it being effective are very low. If you don't have a grip on your prey, you may just push yourself away :)
i have thought of that, so was going to angle the ram downwards at an angle
