I run a similar set up... have a look at the last post on this page...on this thread there are listed all parts you'll possibly need!
http://www.fightingrobots.co.uk/thre...d-diary/page12
Its quite simple and its relatively cheap to build. The most important thing is to have large bore fittings and short pipework...in my setup I connected the QEV directly to the ram, so losses due to length of pipes are the minimum possible.
Edit: I found a photo of the semi-assembled set-up

That is perfect! Also that 4 bar is basically what I was aiming to make... except its already been done. Well if I can get a 4 bar going it will be the first in the UK.
There's already a LP pneumatic 4 Bar, can't remember who made it. I believe there was also a FP, called Flick or something?
Yeah, Flick was a HW from the Supernova team.
Not sure there is a pneumatic 4 bar flipper, there's been a few electric ones though. Are you flipping from the front bars or back bars ?
It was pneumatic
Flipping from the front. I've been examining various setups; Ziggy, Biohazard etc. Now this one from Aus.
I am just not sure what is the best kind of set up on a 4 bar. I downloaded that 4 Bar calculator but it doesn't mean much to me.
I meant to say no FW pneumatic 4 bar flippers. I know Flick was pneumatic ;).
I built one but never actually made it to competition, I have since nicked the parts out of it for other robots.

Hi,
Does anyone know if a 1/2" NPT connector will screw nicely into a co2 nut? Im thinking of buying a hydraulic elbow to go from 1/2" BSP from my paintball bottle to 1/2" NPT. this seems like the easiest thing to do without having to make up an adapter.
Thanks,
Max
Simple answer. they probably screw together. amount of treads per inch is the same. 14 per inch.
BUT
A CO2 thread has an OD of 21.844 mm. A 1/2 NPT an OD of 21.336mm
Do you want to test the threads with 0.6mm of "diameter missing"?
Can you suggest an altenative way of achieving what I need?
Don know if I'm saying something silly as I'm not sure I fully understand what you're after, but...you could use this to connect to the paintball valve:

and this to connect to the co2 nut:

If I understand right, you need an adaptor to screw on a paintball bottle (female 1/2bsp) to get a 90° elbow to a male CO2 extinguisher thread.Quote:

Don't you mean tap a 1/4" bsp hole?
Tapping, threading, whatever, cutting a thread in a hole, yes, that is what I mean.
BTW, I do have such bronze "adaptors". I use one of those for pretesting heavy setups with compressed air.
Sorry I wasn't clear- the point I was making wa should said in your post to tap a 1/2"BSP thread which would leave almost no wall thickness, I assumed you actually meant 1/4" BSP- but looking at a valve I have it already has a hole in it larger than 11.5, can't quite remember as not at home right now but it was something like 15mm. But I guess the principle would work with a larger thread.
Hey Max, I think this is what you need:
http://www.ebay.com/itm/CO2-Tank-22m...item3f1cc537ae
The male part which mates to your co2 nut is DIN477-6 (0.860")
The female part is CGA320, which is interchangeable to 1/2"Bsp, add a 1/2" angle if you need it that way... hope this helps ;)
Hi guys
I've had a quick flick through some of the pages of this thread I cant seem to find the answer, so I'll just post it here.
Which specific Bürket valve do most of you guys use? I'm thinking its the 5404?
Thanks for responses in advance :)
Burkert 5404 1/2 BSP , Normaly closed, 24V solenoid overvolted to 36V.
Main supplier, RS components.
cheers Mario, just want I wanted to hear :)
Which I do have some 2nd hand for sale.
