MagnumBB Posted November 5, 2008 Author Report Share Posted November 5, 2008 It's brilliant that you're doing the male plugs though, i'm having trouble finding some more to use with my begadi system Don't suppose you could help me there? Again, you're doing great work, i hope to get one of your systems in the future! HF No problem. If you can get the OD of the hose for me, I can assemble a kit consisting of female QD unit, Male units and drill and tap combo that you'll need. You'll have to re-drill and tap, but these plugs are much easier to find IMHO and much more robust. For those of you out there, I consider myself as a company that is based on fan service. Because I am a relatively young and small company, catering to my customer's needs are much easier. That said, after this product launches, and my bb's finally hit the market, be prepared for a semi-auto NBB gas rifle. with pre-existing aftermarket support Its pretty much still on the drawing boards, but it will be made. I actually designed my Cold Shot setup to tackle my air source problem. Link to post Share on other sites

I want to have my personal tanaka tapped and tuned for display before I sell any units. If I can't back up any claims, whats the point? Link to post Share on other sites
scar527 Posted November 5, 2008 Report Share Posted November 5, 2008 when you start developing co2 conversions for vsr gas bolts PLEASE let us know!! Link to post Share on other sites
Christafuarion Posted November 5, 2008 Report Share Posted November 5, 2008 So just to check, this system should function in colder weathers, as long as it's not devistatingly cold, and you're reasonalbe with ROF? I'd expect a drop in velocity, seeing that it's CO2, but since the system is double regulated, it shouldn't be such a big deal that you can't use the rifle, right? Link to post Share on other sites
scar527 Posted November 5, 2008 Report Share Posted November 5, 2008 Actually Co2 has a higher pressure than green gas, and the fps is adjustable between o-150 psi, well above 500fps Link to post Share on other sites

Your just concerned about recharge from the first regulator and then the second will handle the fine tuning. If your playing in -10 degree weather... Your gonna be in trouble. The great thing about having a regulator, they will compensate for the drop in pressure at lower temps. Link to post Share on other sites

Well I guess it just comes down to if you're motivated enough to go and play in 10 degree weather.. Hmm.. I think I'll be fine..

scar527 Posted November 5, 2008 Report Share Posted November 5, 2008 Don't forget that heat warmer's will raise the temp of the c02 so if you stick those in the rifle but pouch along with that c02 reguator unit you should be in deep water. Link to post Share on other sites
MagnumBB Posted November 5, 2008 Author Report Share Posted November 5, 2008 No problem For those of you concerned with PSI performance at low temps with co2 please refrer to this chart by WARPIG.com, a great resource for paintballers ( I used the site often when I was a paintballer) http://www.warpig.com/paintball/technical/gasses/co2pv.gif IF you look at the chart, Because we are using pressures well below 350psi, at 0 degrees F. we should be good. And as for why HPA is used often in airsoft and paintball.... ROF and flow control. In a constant stream, a flow of co2 will drastically cool your application. In classics, its the only set back until you make the jump to HPA. HPA is great when you need 3 liters of air in 1 minute. But when you have a fraction of an ounce in 1 minute, you are not going to have massive cool down. Link to post Share on other sites
bjorn Posted November 5, 2008 Report Share Posted November 5, 2008 About real life testing with airsoft sniper rifles and CO2 - in -7C a 12g Co2 adapter from begadi gave still ok results when shooting a KJW M700 @ 170m/s. The velocity was slightly lower, but you can always tune up the pressure. If you use it normally you wont even suffer cool down. Link to post Share on other sites
Stuey Posted November 5, 2008 Report Share Posted November 5, 2008 Don't forget that heat warmer's will raise the temp of the c02 so if you stick those in the rifle but pouch along with that c02 reguator unit you should be in deep water. That's a great idea - I take it you mean those little hand warmer things that hikers often buy? And BTW I thought that "in deep water" meant you're in trouble? Is it different across the pond? Stu.

I think you mean drill bit, not drill, lol. Not a big deal, but some people would be strange enough and try to hold you to that. Just curious.. And of course you don't have to answer. How many units are you buying for the first round? Thanks, Chris Link to post Share on other sites
MagnumBB Posted November 6, 2008 Author Report Share Posted November 6, 2008 Hmmm, Thanks for the catch Chris, As for my order size, because I am doing this on a pre-order/contract build basis. I'll order as many I need to cover a week's worth of builds. After I release some kind of demo video, I'll open up my website and allow orders in. Once I get say, 10 orders or after some kind of deadline, I'll stagger one build group as datexx-datexy and so on. That way I don't have to order parts every few days. So, 10? maybe 20? Heads up, Shipping will be a flat $10 in the states and $15 for international. Link to post Share on other sites

Heads up, Shipping will be a flat $10 in the states and $15 for international. Is it possible that you can sell unassmbled kits with instructions at a lower price? They will normally be pre-assembled, I assume. I ask this because I'm sort of DIY-oriented and I like seeing how things work and are assembled. Also, I wouldn't mind a slight bargain and getting my hands dirty, assembling it myself. Can't wait to see more videos of this. :thumbs-up: Link to post Share on other sites
MagnumBB Posted November 6, 2008 Author Report Share Posted November 6, 2008 Top Spin, You have incoming pm Galactica, I wish I could help, but because shipping the parts to myself to assemble, would take about 2-3 days and I am unsure how long you will be here. On the bright side, Shipping international will only be $15 Link to post Share on other sites

MagnumBB Posted November 7, 2008 Author Report Share Posted November 7, 2008 [update] [some things discussed over on ASF that I would like to mention here] [Discussion about the use of Co2 vs HPA for Bolt actions] For those of you concerned with PSI performance at low temps with co2 please refrer to this chart by WARPIG.com, a great resource for paintballers ( I used the site often when I was a paintballer) http://www.warpig.com/paintball/technical/gasses/co2pv.gif IF you look at the chart, Because we are using pressures well below 300psi, at 0 degrees F. we should be good. Peak you probably won't need more than 95psi in all honesty, but who am I to mandate what FPS you shoot your rifles from. And as for why HPA is used often in airsoft and paintball.... ROF and flow control. In a constant stream, a flow of co2 will drastically cool your application, in our case the rifle. In classics, its the only set back until you make the jump to HPA. If you fire a stream of bb's for too long, you'll pretty much freeze your regulator and secondary regulator. Your going to be out of the game for 2-3 minutes until your system thaws and then your back in ( I am speaking from experience) This is where HPA comes in. It allows you that nice and happy stream of shots without the massive cooldown of CO2. Even with HPA though, You will face freeze-ups when you are firing in a squad gunner role, ( again, speaking from expereince, escort powered 1919a6). HPA is great when you need 3+ liters of air in 1 minute, HOWEVER when you need a fraction of an gram in 1 minute, you are not going to have massive cool down, PERIOD. To compare to the anatomy of a paintball gun, when you tap your magazine, the existing green gas reservoir will now act as an expansion chamber for your rifle. In a 10rnd Tanaka magazine, it'll be a pretty decent sized chamber and in a 29rnd magazine, your pretty much covered in terms of expansion needed. Adding to the expansion, you have your hose, which might not seem like much, but every available open space counts for hitting that capacity. In a double stage regulator setup, your rate of fire is going to be limited. which is why a bolt action is perfect. by the time you cock your bolt back, the system will have already equalized and your good to go by the time you slam for bolt forward. [About the regulator] Questions: Brainplay -When setting the pressure you "click" the adjustment knob. To change the pressure do you "click" the knob again? -Also, is there any sort of set screw or insert that can keep the knob from being clicked again accidentally (or DIY like tape or an o-ring)? MagnumBB When you "click" down on the second regulator, it is a movement cap that prevents accidental knob deviation. To re-adjust pressure, you pull up in the cap and turn as you please. On the first regulator, because the knob is integral with the regulator unit, pressure is applied and makes accidental adjustment near impossible. I am thinking of placing an o-ring on the first regulator to act as a buffer. Keep some liability away from myself from those who decide to fire their rifles at an unreasonable FPS. Brainplay -Should the hoses be damaged can they be replaced, and how? MagnumBB The hose is in common supply, Nylon 11 in 1/4". I get most of my parts from a local supply hub. I am more than willing to offer replacement for the hose between the regulators and 2 feet needed to the rifle for 1.50 + shipping. I am currently contemplating whether or not I will sleeve the hose with a paracord shell to offer some protection and increase its good looks. Brainplay "Great job so far. The tap kit included is a nice bonus" MagnumBB The tap kit was intended mainly for those players in the UK, where sending in magazines and paying for return shipping was not feasible. I figured I would extend the offer to any of the DIY warriors out there or those who want to try it out. Christafuarion -How are the fittings attached to the hose? Is there any glue involved? MagnumBB No glue is involved. just a clasping ring w/ teeth on the inside of the fitting. Christafuarion -When you disconnect your hose from your mag (in a tanaka setup) for a mag swap, and there is still gas in the caplet, what will happen? Will all of the CO2 come shooting out? Or is there a device that cuts off flow when the hose is detached? MagnumBB The female QD unit has a shut off valve built in. When the magazine is detached, the air from the magazine will escape, but the gas in the system will be preserved. I could make the magazine function the same, but keeping magazines pressurized is a bad idea. Christafuarion -Also, how are your BB's going? When do you get batch 8? And are you doing .36? Or .36 and .43? MagnumBB Batch 8 is colored differently since we changed the material. we nailed 0.36g and 5.98 +/- .01mm, but it is a light tan color. we are experimenting with a dye that might bring down the weight to .35g, but since it is a good compromise, I might run with it. We'll only see. ------------------------------------- Video of Fps deviation on a tanaka will be uploaded Monday night PST. Website opening the following Weds. Link to post Share on other sites
