The I wants

do we really wanna start this?

because this is gonna take me longer than it took to write the science guide to get everything on my list.....

but we could stard with an hpa compressor.

 
Erm, it's an MP7... Is there something new about this I should know? 

 
Yeh, ones that can go anywhere near 3000psi are seriously big money. Even that ShoeBox thing is nearly a grand I believe and takes an hour to fill a bottle.

 
Be a man and get a stir pump ?

Actually, every time I check Instagram there's a I Wants thingy :(  I should just accept the fact that I can't afford anything :(

I can get you one of these, but they be damned expensive!

Yeah thats why its i wants rather than i haz

Sadly theres only one site round here has one that only goes to 1.5k and its not a good site.

Lot of cash to avoid one place, but i'm trying to ingratiate myself with the local dive clubs.

Have you considered looking into the uses of Hi pressure compressed air and seeing what company’s use it? Then perhaps asking very nicely if you can fill up a bottle every now and then.

It might be a flat no, but you never know unless you ask.

 
Get a filling station adaptor, dive shops will appreciate that you're not destroying their filters :)

1.5k is a very low fill, but from your sentiment I’ll take it that it isn’t a typo and that they are conserving the fill pressure.

Running and maintaining a suitable HPA compressor is expensive and is typically run to a cylinder bank topping up as required while fills are run from the master cylinder.

So it does make a bit of sense that they would restrict fills particularly for airsoft down as far as 1.5k - particularly if only a portion of the airsofters are on HPA

Though I’ve not been to the type of site for a while, I believe that it’s still the case with a

lot of paintball sites across the country still run CO2 systems.  Delta Force is the market leader for punter games.  Independants that market paintball to punters alone dont need HPA and the investment to convert is at high expense.

A site that markets to own gunner walkons/scenarios/tournaments has to have HPA, normally at 3000psi and bringing in specialists such as HPAC for 4500psi at events.

Sites with wise management will diversify which can mean HPA fills are available for airsofters, but doesn’t guarantee it as they may not want to run compressors if it’s only an airsoft day, or there may be seperate staging without the air system.

If you can get the fills without paying per fill then VFM and convenience for portable HPA is to have multiple standard aluminium 48ci 3000psi cylinders.  (Though 4500psi fiber cylinders are available the standard 3000psi beats them on VFM) Fill enough of them to cater for the air you need for a day or between fills.  Friendly scuba clubs can be good for this.

Next is your own scuba cylinder.  Go for a convenient size rather than just big as the pressure will soon drop and you ‘waste’ more when it gets too low.  This can be filled at pretty much any scuba shop and will cost per fill.

Get better efficiency with 2 or 3 scuba cylinders

Fill your playing cylinder as often as possible to minimise the pressure gap

Primary from cylinder no 1, top up with no 2, second top up with no 3 if you have a third.

When 1 is too low to bother with then take it to the scuba shop and now primary fill from no 2, top up with 3, and final top up with the full no 1

All of this is probably overkill unless you’re going through a fair bit of air, so the most reasonable would be one scuba cylinder and keeping your max fill as low as possible to preserve the scuba pressure as long as you can 

Stirrup pumps are a posisble solution, but you need to ensure it has a good filter system and it will take some effort...... I’m going to be trying one next year, so can give some advice from experience as opposed to having watched in the past.

The Shoebox compressor is a solution to a problem we don’t really have in the UK.  It’s for remote locations with difficult access to HPA - real remote locations such as in Canada as opposed to the Shires here

It’s not a true compressor but a booster that needs a source workshop compressor at >100psi and it boosts to 3000 or 4500psi - Over a very long time, and at risk of overheating so you need to keep an eye on it

Compressor or cylinder?

Because if it's the cylinder overheating you can just fill a bucket with water and leave the cylinder in there.

The compressor 

From shortly before 4 minutes in is relavant showing how he has left off part of the casing and run a fan. Though it is filling a small scuba cylinder from about 3900 to 4500psi in 2 hours with a couple of stops

Some of the stops he experiences are pressure related.  As he makes adjustments and due to the age of the video I would say that it is the first Shoebox model, with the latest having settings suitable for 3000psi or 4500psi



 
just watched the video, gotta say, good luck to you guys, I'm gonna avoid all that kafuffle (& expense) & stick to aegs, just plug it in & play, lifes too short lol ?

Quite the write up there lol.

Yeah its 1.5k, they run paintball as well which is why they have a compressor, sadly as an airsoft site it's plagued with cheaters so i dont like going there too often. On site its ok running that low as its easy to top up between games but if i wanted to take a charge elsewhere its not ideal.

Debating multiple options, a fill station is a possibility getting the local dive clubs to charge it up to proper pressure, would only need to last a few charges for a single game day, mainly for when i want to run at sites without compressors.

Not sure on hand pumps, heard they're pretty hard work, although potentially might enlist a mate's help to convert one into an ersatz compresor. Shoebox is another possibility as i do have access to a 125psi compressor pretty easily and a couple of tippman cylinders would probably do me for a day (except against cheaters, but they all live at the one place with a compressor so thats fortunate)

 
All of a sudden seeing as I’m toying with the idea of venturing in to gas guns this coming year I’m VERY happy indeed my home sites have HPA fill rigs set up on site !

Lol

Its mainly a protest thing, dont want a badly managed site to get my money *just* because they have an hpa fill rig.
