So what I read is the green gas only gets to 115-130psi but your pump would do 150/160 would be more power. You’ve got me super interested in these shells now that I don’t need to buy green gas all the time and don’t need a special HPA valve
Green gas is basically just propane/LPG with added silicone lubricant but no added smell. It's stored as a liquid in the can/cylinder then expands and cools as it's loaded into the 40MAX tank, then expands and cools some more when the 40MAX is fired. All this means that performance is noticeably affected by ambient temperature... a hot day will give you higher pressures/better performance vs a lower pressures and performance on a cold day. On a 20˚C day, a 1-second fill from a green gas can will give performance equivalent to about 180psi of compressed air. A cold (10-12˚C) gives disappointing performance; and hot (30˚C) day and things get spicy. The compressor I'm using here is an "Air Hawk Pro" which is quite a good quality unit with a powerful motor, large piston volume and solid cast metal cylinder/head unit. Its max. pressure setting is 150psi and if connected up to the 40MAX directly using a Schrader (tire) valve adapter it will stop there but kinda over-run to and will reach about 160-180psi. Downside of this set-up though is that the Schrader adapter is poking out the back - OK if you're leaving it connected but not great if you want a stand-alone "shell" to load into a launcher . If you're using the needle-type adapter it'll max out at 150psi and probably give you slightly less pressure in the tank by the time you disconnect. If you are only using compressed air in the 40MAX you'll have to add silicone lube every now and again. I'd recommend stripping, cleaning and lubing the whole thing every 200 shots or so.
I'm really interested on how did you make/get the adapter for the compressor to the 40max fill valve, I'm an airsoft player and a tool like that would be so useful
The air-compressor adapter ideally needs to replicate the fit of a standard spigot on a Green Gas can... In this case it's made from a standard-issue ball-filling attachment that'd come with pretty much any pump or compressor, but with the addition of an aluminium sleeve slid over the attachment's tube to fatten it out so it can seal more closely to the inlet valve (more below👇👇) See picture and more explaination on Imgur here: imgur.com/BGGYCnj A small o-ring is slid onto the spigot first to provide a seal between the bottom of the aluminium tube and the spigot's base, so when you push everything into the inlet valve everything holds together well enough to reach the (nominal) 150psi limit that the compressor can achieve. It's a bit leaky and not 100% reliable, but for the most part it works. Stand by though; I've just got a ø6.0x0.75mm tap and die set so I should be able to convert a bicycle tire's Schrader valve to replace the 40MAX's inlet valve. Will let you know how it works, but hopefully it should eliminate any leaks so we can get the most out of the tiny little compressor, plus get an accurate reading of the air pressure it can achieve.
The thread is M36x1 if you wanted to try, but they actually have their own version of the Taginn shell/barrel in development too: instagram.com/p/CUpEZdOFvnR/
Absolutely. The only reason I haven't done it yet is I only have the one so far and still have some testing to go with it 😅 The thread on the inlet valve is M6x 0.75 so not immediately compatible with the usual push-fit fittings, but it would be entirely possible to drill and tap on the opposite side from that valve for something with a small thread like a M4, M5 or M6 (1/8 or larger is probably too big) www.aliexpress.com/item/1005002990608089.html You do have to disassemble periodically for cleaning and maintaining the o-rings, so design with that in mind.
@@wadekirby8575 The ones pictured are an access spigot for plumbing: www.bunnings.co.nz/marley-32mm-optim-access-plug-spigot-end_p0336513 It's a fairly specialised piece of gear and I don't think it's available world-wide. More recently I'be been making them up out of medical-grade baby-bottle fittings (which DO actually fit a lot of baby bottles) but the idea would be transposable to anything you could find locally. Have a scroll through this Imgur album - it's a mess, but something useful might be in there... : imgur.com/a/AmhrMlk
Yeah it was a bit of a punt, but the shells themselves were such a good price I figured even if I could just check out the innards I'd at least see how these things worked. Because of the tiny tank-volume though they only excel at spigot-launching and single-barrelling things. Still, they can fling a handful of 1/2-darts down a loose bit of brass nicely 😀
@@archiedrury2676 I don't really know yet. I've been experimenting with LPA ie: low pressure air (≤180psi) provided directly by a small compressor that would be housed in the stock of the blaster... pretty much to avoid having to deal with HPA and the sorts of tanks/connectors/regulators that are required for such high pressures (hundreds of PSI).
@@archiedrury2676 Sorry, again I'm not familiar with the types of adapter that you can buy... the one I've used in the video I made myself from a ball-inflator adapter and some small aluminium tube: imgur.com/BGGYCnj You could try asking about commercially available adapters at an airsoft store - they'd certainly be easier to and more reliable to use ;)
I've got one set up now to attach directly to a small air compressor so need to shoot some more footage soon and will include tests with nerf ammo. Once it get warmer here 😆

Could you please do a video with this direct line for hpa and a half dart test even if indoors if possible
Do you think it would be feasible to thread the fill valve for a direct line and convert one of these into the main part of an HPA blaster?
Absolutely. The only reason I haven't done it yet is I only have the one so far and still have some testing to go with it 😅
