here they are, pictures of current progress with my m2hb gun, the grey bits are in steel and the brown bits are in resin, the resin bits still need to be modified as they arent 100% accurate to the real thing but it's getting there. and sorry bout the crap picture quality it's the best camera i had at the factory. here is all the parts laid out and here it is being held toogether

wicked.... ;D so long as it isn't wire up with bailing twine... could be quite the mint job. try to keep track of costs... you might want to mass produce ;D FC

I can say that if you do decide to mass-produce this, you'd become a VERY popular person with almost every airsofter ever.

Indeed, keep track of production for potential to draw up mass-production design potential. If ya can't mass-p yourself, at the very least, consider selling rights (with royalties ) to someone who can. ALSO, ideas for tripods with gun sheild mods and shorter mods for mobility (no harm in sketching out ideas for the future, best do it now while the technical ideas and concepts are still fresh and active).

you can market it to Hummer owners in the united states for the serious wargaming bunch, or advertise it for Operation IRENE -The potential THERE would be totally fkin insane: i'm sure there are loads of nuts who will be willing to invest a lot for an airsoft .50 cal. Even local airsoft sites - might invest in one.
Got any insiders scoop with respect to how its gonna fire? - C02? AEG?
and rate of fire - real thing isn't tht fast tho
and most importantly, whats this gonna fire? 8mm - muhahahahaha -
Damn fine job i say - keep up the progress

i would think AEG would be the best root... a solid SAW gearbox and motor would be cheapest... and long lasting option. FC

but then you could just have a saw mounted on the humvee - somthn tht is done - its gotta have a special sorta Kick - M82 uses 8mm, why not an MG which uses the same ammo or at least have it gas or somthn - with some real recoil kick - now that would be a winner m249 gearbox is probably the best place to start, maybe put a psg1 barrel in too, you mite also manage with a tracer unit mounted right in the tip of the mg - give your night MG assaults a little tracer fun ;D

Tracer might indeed be an interesting idea, even if it is just a simple laser-only device.
I think using 8mm would be amazing but the difficulty in trying to build an electric system around that would be enormous; unless you tried some kind of eletricaly operated gas-powered sytem which basicaly hybridises AEG and 8mm gas technology, that works in theory at least.
And yeah, the American market would eat it up, but so would the rest of the worlds rich peoples. I mention multi-mods only to potentail expand not only play possibility but marketability.
In terms of finer details, the STAR 249 includes a sustain-fire purpose built gearbox with a synchronised eletric mag feed. If you literaly just transplanted the internals strait in, you would end up with a nice basic package for your HMG. Then, you can install a high power low rof build inside for realism.
BTW, also keep in mind that the practicality of building a rotary cannon, though more difficult, overlaps in many respects with your HMG project (mostly on the practical construction side of things) so thusly I suggest, just as a thought for now, to bare a rotary cannon idea in mind and make notes achordingly as you build your M2.
Many products on the market today have been built out of ideas spawned from napkin scribblings written during the development of different products.
I for one would love to work on a rotary canon project one day and would value any and every scrap of advise and info from any such related project that could benifit the idea.

Use the CA m249 gearbox, not the STAR.
The CA has more part compatibility with TM spec internals, unlike the STAR.
It's also metal and a hell of a lot better, generally speaking, than the STAR.

True, use the feed syste from the STAR for the synch feature, otherwise yeah a decent gearbox is better.

honestly, i dont have the funds to buy a whole m249/m60 and salvage the gearbox, if anyone knows where i can get a CAm249 gearbox for less than $600 please, let me know, i'm stuck with using a broken v6 gearbox untill then. The gearbox must have a trans-mounted motor. (maby that new chinese QBZ?, that's trans-mounted, not built for sustained fire tho)
Tracer, hmm, cool idea but really expensive bbs right (i think)? it would be no ppoblem to put the tracer in the barrel since it's so large, another idea is to have LEDs shining on the BBs from the magazine (someone has a product like that)
Another thing, Using a PSG1 barrel wouldnt work without a bore-up kit to get the sheer air volume needed, on the final thing, the inner barrel would finish long before the outer barrel
GAS: may be onto something here as a whole gas canister could fit in the reciver (or maby not, may need to have just a big gas resovoir). Anybody know any reliable automatic gas systems with external feed? a gas canister should fit in the reciver. just.
8mm. Not really viable, i dont think there are any AEG nozzles designed for 8mm and i'd need an EXTREME bore-up kit for the extra air volume.
I'm not looking to make a rotary barreled airsoft weapon anytime soon, i'm just not up to it (is the existing minigun use gas or electric to actually fire the bbs? i thing the barrel spin is electric but i'm not sure about the firing mechanism.
mass producing this shouldnt be a problem, i have injection molding for plastic and aluminium, but for low quantity batch production, sand casting aluminium seems like a better idea.

all v true points -
Tracers: someone did demonstrated in a video - used an LED flashlight just Flashed the bbs for about 2 seconds, and hit the lights, they were glowing a nice green.
turn it on before you start, in about 1 minute - tracers will be rockin and rolling.
A suggestion for the g/b would be to wait for the china m249 to release - it'll be cheaper than the star and CA for sure.
If you're lookin for a gas system - the paintball canisters, not too big or heavy, and quite common interms of adaptors and nozzles ect. problem = gassing it up and finding a reciever.
note: sirrith is sellin a sun project XMII. C02 power, but its $$$ and not working. If you want a really extensive DIY job, tht mite be an option

Cheapest way to do tracer fire is to put the UV bulb inside the clip itself.
For a gas system, bah, not so sure; trying to rig up a home made eletrical system to auto-fire for your single gas system would be too complicated. As for full auto gas systems, not sure they make em anymore so replacement parts and mass production would be a bitch.
I say go for pure electric for now, keep it simple this time around. If you really want to try, wait to build an M2 2.0 version project, that way the secind time around you're jsut cloning your own design and only have to really think about the gas system.

dont make it 8mm.. the market will go way down if you're planning to sell. if its just for yourself though, 8mm would be fine.

Tracers respond best to UV LEDs btw.
Use a CA M249 gearbox - they sell them for $330 including all the specail gubbins such as trigger mosfet relay and 8mm bearings - and a CA M249 hopup - they sell for $120 and feed from the side - and then maybe a Bore-up kit to give extra volume to use a longer inner?

Cool. I'm still exploring maching gun options myself, doing research and gathering intel on possible options for an internal overhaul of my 249. It's alright at the momment, it's just not all it can be.

With non-star gears and motor though, but yes I know, I realised that at the time heance why I'm now gathering intel.

Yoni... I'll have 2 x A&K M249 para gearboxs 4 sale... in the very near future. eg: got the saw's.. just got to pull the gearboxs. would be a good base Gb to start with FC

Post by yonathanho on Dec 26, 2007 2:50:37 GMT 8
theyre the same as the CA ones right?
i was going to get a ca gb and hop up unit to cnc the front reciver to hold them. i hadnt thought of the chinese clones.
however i may be in the US until February so the project is on hold untill then

I'd reccomend the CA boxes over the A&K ones - the A&K boxes have some major QC issues.

I meant the actual Gearbox Shells. They can't take aftermarket motors, for instance, and the slot for the cylinder is too long.

worked on the feed port and the link ejection port today. the feed port isnt 100% accurate but it's gonna be mostly hidden by the box and 50cal chain. have pictures but no card reader here in china
