  • Middleweight Pneumatic Rams

    Hi all!

    So after about 2-3 years of regularly building and fighting beetleweights and the odd bit of live event feather rumbles in between, I thought now would be a good time to try to make the move towards higher weight classes and having seen them fight the middles seemed very appealing to me. With that in mind, I figured I'd post up here just to get some ideas from folks and see if the forums are still seeing much use!

    As you've seen from the title my main question here is about pneumatic rams. I'm looking to build a pneumatic hammer and have been thinking to use a 63mm cylinder diameter ram on 10 BAR to power the weapon, using your standard rack and pinion gearing setup. My question is, do people think that'll be powerful enough to cut it? What size rams and pressures are people using in whatever they've built? 10 BAR feels a tad low on instinct, as I know feathers often use 8 BAR for their systems, but it's a lot easier to get 10 BAR parts than say 15 BAR.

    Hey there!

    In terms of MWs, I am not convinced 10 BAR would be enough though that is just my opinion. It'd work for sure but I am fairly sure both Backflip and You Little Ripper, which are both rear hinge flippers, run higher pressures than that though having said that, Backflip ran 10 BAR in 2019 by the looks of it (ref: https://www.fightingrobots.co.uk/thr...4221-regulator).

    Probably worth PMing Tom (Backflip) or contacting Jonno directly?

    Looking forwards to seeing what your creation is. I still need to get my electric axe working.

      Ah that's interesting to know! I had another ram lined up that's happy to run at 12 bar nominal so o may have to switch up to that. I fear beyond 12 Bar I'd need to either over-pressure the system or get something custom/specialist which would be rather a lot! The bigger ram has a MUCH larger bore and stroke so that may get me around the lower pressure but I'll definitely do some more research

        10 bar is pretty standard for LP pneumatics - thats what most axes run when using Co2

        Really then depends on the size of the ram to compensate, and tbh im not really sure what would work in a MW. Generally Axe rams tend to be larger, but honestly couldnt really help on that as i dont have extensive experience with axes to really know whatd work in a MW

          Having spoken to a few people, it seems Thor uses a 140mm bore cylinder whilst 63mm is what a few people suggest for a flipper. I've managed to source a 125mm cylinder with a 175mm stroke for a cheaper price than it would've been to get a 80mm or 100mm so I'm going to work with that. It's rated up to 12 Bar and I intend to build for that if I can, but it's good to know 10 bar might work if needs be
