Hi,
My last air cannon was a quit simple single shot air cannon made out of no time but i now want to make a multi shot ball bearing rifle. I want to use a regulator to be efficient of my air and I was wondering if anyone could draw a basic diagram of one.
Also would a 1/4'' quick exhaust valve be to small to get a quit powerful shot.
Thanks Please Reply - Andrew_J

it is kind of hard to make a rifle regulator. easier to buy a paintball one. but if you want regulated presure at lowest cost i suggest a qev + pop off valve as pilot. i think wyzz has made one.....
but you have to know most of top airrifles comes without a regulator. The regulation effect appears if your gun is well made, you dont really need a regulator, if you use low pressure like @ 30-40 bar......

come undone
Here although I highly doubt you would be able to replicate such a design with very basic tools and equipment.
If you're really keen on the idea of using a regulator it doesn't actually cost that much to buy one for paintball, with really low end ones ranging in the £15-£20 range.
But, as bravootome said, a lot of PCP rifles using a hammer valve are self regulating, where you can adjust the output power by adjusting the hammer spring strength and doing a bit of fine tuning, so if you want a fairly compact multi shot PCP, I would go for a hammer valve based design, probably save you a few quid .

In very crude terms, this is a basic diagram of a regulator:
It's not spectacularly difficult to build something to this kind of design, but the question should be asked as to whether you can buy something sufficient for your needs, because that will be a lot easier and less prone to going wrong.

Does that thing kinda look like a big cat to you?
Indeed it would, Wyz did a very good tutorial on converting a blowgun to a hammer valve a while back, have a look, saves on you having to design and try and fabricate your own, which can be quite a chore for someone who I'm guessing doesn't have access to their own lathe. and given they only cost around 3-7 quid, it doesn't really break the bank to experiment and play around with them.
Just, when you're making it, ensure you maximize flow on all your components for ball bearing firing.
personally I think using a chamber at pressures of around 250 - 300 psi would be a good idea (or more if you're really power hungry) with those kinds of pressures and a powerful hammer I've put 3mm ball bearings straight through soup cans, and that was with a really inefficient set-up, I'm sure you could do better with a good flow and larger bore
Hope that helps,

Some can go to 600 psiAndrew_J wrote:My compressor can only pump to 100 psi max, but ive hear little about shock pumps and what pressure can they go to?
A bicycle pump is intended to take a relatively large volume (bicycle tyre) to a relatively low pressure (around 40 psi).What the difference between a shock and bicycle pump?
Shock pumps do the opposite, they take a small volume to high pressure. Any chamber over a couple of cubic inches is a pain in the shoulder to fill.
Not can, still answered.Please answer if can
