Hmmm that's a little short for what I want, I was looking for about a 150mm stroke ram....

I'd say that's a little too large for a feather :P

shockwave (LP flipper from team ocean) had about 60kg worth of flip and that could flip a FW oota. and that system didnt even have a buffer tank

Just to clarify Shockwaves specs as you mentioned earlier. Shockwaves pneumatics have remained unchanged since it became Eric Jr its a 40mm Bore 60mm Stroke ram and the max pressure is 11 bar set by the PRV.

Just need to get those blasted LED's hidden by the Robo-Coat before the next event

alex, my 30mm bore ram is 100mm stroke and the 80mm bore is 50mm stroke

[Bodge Job]

Ahh, the 30mm bore 100mm stroke ram may work, but I thought u were using it for your fliper?

[Bodge Job]

wait, i have done some more calculations, and that ram would only give me 6.43kg of lifting force, so i need a 50mm bore 100mm stroke ram..

this may work, but its a shame its from the US... but its still only £30 ($50) including postage...
and a rack:http://www.beltingonline.com/1-5-mod...teel-rack-6801 and gear:http://www.technobotsonline.com/stee...-38-tooth.html that should give me just over 200 degrees of movement with 18kg of lifting force at the tip of the lifting bit...

I would have thought you would get more lifting force than that from a 40mm bore 10 bar ram

[Bodge Job]

Yeh, buy with the gear ratio I'm using to get the 200 degrees movement, means I need a lot of power, and 40mm bore cant provide that...

[mattsdragons]

I might get just enough if I run my system at 11.5 bar

[Bodge Job]

yeah, but i haven't found any rams that work at that pressure...and i'm using quiet a long axe arm, so if you used a shorter one, it could work for you.
