BW pneumatic axe

[Shakey]

Sorry for being here but it doesn't fit anywhere else.

I plan on building a pneumatic CO2 flipper for a feather weight (don't worry it will be an unusual design, no wedge for me.) but I figure I out to do a small scale test first. With beetle weights being reasonable popular I figure why not.


Just to be clear the ram wouldn't be positioned like that in the final robot it is just their to illustrate the linkage.

I figure a double action cylinder so I can return it quickly. I also think that seeing as an axe is more about speed of it that I will not need a large diameter but a reasonably long stroke would be help full.

What I cannot figure is what size tank I should use. And I know it has been asked a thousand times but.

Is it tank>Fill valve>Isolation valve>Dump valve>Cylinder valve thingys>Ram/actuator?

With suitable piping to prevent it from freezing.

Cheers,
Alex

that would be hard to get into a BW try an electric axe

[harry hills]

i think a terrorhurtz style system would be better, as the axe won't go far enough down

rack and pinion is what you want.
with that arrangement your axe will hit your cylinder

Might be worth asking some questions on the RFL forum, there's been a handful of pneumatic beetleweights over there
