An end to gas being anyway expensive :)

Lethal: not exactly hard to throw a 35litre cylinder into the boot of a car, they're big, but not that big, and a group of people could share the cost of it

tbh, i think ill just stick with the 1litre tanks for now

ED E · 26-06-2007 12:55PM

Yeah, but my dad leaves in the car, but we could plonk it in the safe zone...still havent found an 80% limitor.

there are 4 of us but only 3 have gear and I'm the only 1 with a GBB atm, but my brother might get one as hes getting a sniper. So, those bells actually any good?

If you know the PSI of a full tank you could probably use a gauge to insure you didn't fill it over 80%. No idea where you'd get one though.

Are you saying to fill mags straight from the tank Nonex? We could do that yes but lugging one of those around...not so easy.

What specifies if a tank is non refillable, if the manufacturer puts it on the lable? Because in actual fact they are easily refillable. Got any linkies to all the legal stuff?

yes you fill mags straight from the tank.
and all the legal stuff, you can see me and i will show you the markings on the top of the tank.

No, we wouldnt. the 80% is 80% of the tank is liquid, doesnt increse the PSI i dont think. What they do with some tanks at least is have a spit valve on the top which spews when its at 80%. I cannot determin if thats what the second valve is.

Fiach Dubh · 26-06-2007 02:30PM

The more I look into this the more it just sounds too dangerous. I was listening to a podcast interview with the guy who invented the propane adapter and he talked about the 80% issue. Apparently it has to do with evaporation to condensation equilibrium, where the propane is doing both at the same rate and maintaining it's PSI (120 PSI at 20 degrees C) if the tank is filled too much with liquid propane the PSI will rise rapidly reducing the pressure tolerance to heat. A Bernzomatic tank is rated to about 50 degrees C but an over filled tank will have a much lower tolerance. The flow valve to release pressure may not help you during refilling if the liquid propane is introduced too quickly the tank may bulge or rupture.

He also told a story about how a guy left a green gas tank on top of his car during a sunny day at a game, stupid thing to do but it proves a point. The tank exploded of course and shrapnel ripped through the cars solid roof. Refilling a tank without the correct equipment could be like holding a hand grenade.

i think it boyles law,you need to read.
from my diving days
all gas will turn to liquid with temp and pressur.
just use a weight scales the big tank has to be upside down to fill the liquid in to the small tank, i dont think you wound get 80% in to the tank because you'd have to ven't off the gas as you fill it to get more liquid in,
thats how lpg for cars works you have a ven't at the top of the thank and you open it when you fill the tank, it lets the gas out to fill with liquid and when you see the liquid coming out you stop filling and close the ven't.

ED E · 26-06-2007 03:36PM

The trick togetting the full 80% is temperature

Put the one to be filled in the shade with wet towels and the filler in the sun. Changes the balance, then when the spit valve starts we cut it off.

Also its illegal to refill the tanks anyways, they are property of the company who filled them initially and so they could take you to court for illegally stealing their money.

THAT IS FOR THE LARGE TANKS. Yes, they are the companies propertie. The small one which i intent to fill are the consumer propertie:p

Finally got gas for it today (thanks Max_Force!), it stinks really, really bad but it's worth it. Although my first GBB, I have no complaint about it other than its accuracy. It's very heavy, full metal is excellent, nice crisp blowback and decent range for a pistol. The best thing about it is it's price. AFAIK there is no hop-up which is annoying, it spins off to the bottom left and isn't very accurate, although some shots go perfect. Well worth the money!

moneyman: might want to try giving the barrel a good clean, alot of clones have very dirty barrels when they come out of the box and this can cause horrible inconstistencies in shots

Found an adapter thingy online today which allows for refilling small propane tanks from larger ones (somone mentioned it in the thread on ASI that lethal started about this)

Not sure yet if ill actual use it, but ordered one to see what they're like, will post a review of it when i receive it, but it's coming from the US by ground mail, so will be a few weeks

ED E · 26-06-2007 10:23PM

Have found said adaptor on ebay for cheaper

The only prob is that is an american so it'll fit the 1l but not the larger tanks so I'll get an adaptor on a pipe.

whupass · 26-06-2007 11:10PM

they are called disposable tanks becasue they aren't designed to be refilled, i wouldn't recomend it and won't skirmish around one that has been filled

As said just before me, these are disposable tanks for a reason...I can see this all ending badly.

EDIT: Im not trying to start an argument, simply expressing my concern for your life and the lives of the people who use your refilled cylinders!

CrazyRabbit · 27-06-2007 02:14AM

I don't want anyone to go BOOOM, so please be careful!

turn cylinder upside down fit a reg, hose, adaptor, job done and within the law.

Would you consider having one of these in HRTA at the weekends? Well mabey not inside because of the fumes but somewhere outside(in the shade) where we could pay for each refill? Or mabey pay extra at the begining? Im sure there would be a good system where we wouldn't have 3 or 4 people owning a tank and having to fight over whos had more and what not. This way you could make a little more money, people can still have really cheap gas and most importantly I wont have to find another 50 quid fora propane adaptor. But i'm sure you've already considered this.

And another thing is the propane adaptor. Will it be able to take the constant cooling, contracting, warming up again, expanding, cooling etc.?
It'll be getting pretty heavy use... Maby im just being silly though...

Shiva · 27-06-2007 12:37PM

When my disposable propane tank is emptied, its gets disposed of.

Aint no way in HELL I'm going to try refill it, or let anyone else try.
The warnings on the bottle are there for a reason folks.

ED E · 27-06-2007 12:44PM

Listen my dad is Uber safety concious and is not willing to take any risks. We are not going to do ANYTHING unless we are sure its safe. I've reading articles online and if that is a spit valve(determinig that now!) then as long as we disconnect it when it spits then I'tll be jsut like new. For safety there would be a limit to how many times a tank can be filled due to internal moisture corrosion(rust).

Shiva · 27-06-2007 12:49PM

I wish you the best of luck.

Just let me know when you're attempting it so I can make sure to get to a minimum safe distance

ED E · 27-06-2007 01:06PM

Well we'll attempt it at home first so as long as you don t live on my road you should be fine:p We will need to see if it fills the same amount...thats gonna take a while with my m9. Oisin, could you lend your mac 11 to the cause?:p

whupass · 27-06-2007 03:02PM

ok so you live in churchtown right? well i'm off to mayo post up when your house explodes so i can come back and start rebuilding my house
