QuoteYah, I think I am going to do three things:
1. Get a longer barrel (I measured last night and the barrel length was only 11.5 inches). I am thinking of trying a 18" barrel.
2. Change the braided steel hose that runs from the valve to the barrel, to something with a bigger diameter.
3. Figure out some way to make an air chamber. (This will be the hard part)
1. You could go with a 18" barrel but I don't think that's your problem.
2. This definitely needs to be changed. 1/8" hose is not going to cut it. The primary concern on the outlet is to flow as much air as possible. My suggestion would be to build a hardline out of PVC, maybe 1/2" or so. Could even go CPVC to keep it smaller on the OD.
3. You could need this. On my gun I used one of these lines (Have to check at Lowes for the pressure rated one). I would suggest an on board air system.
And a question: What type of sabot are you using to hold the balloon? I use two dixie cups, stacked, glued together, then cut the sides into quarters. Give it a try. This may help to create a better seal around the grenade.
08 March 2008 - 01:20 PMYour design will not work how you think it will. You'll be darn lucky to get 50 ft. out of a nerf with a 2" barrel. Simply put the opening time of a ball valve with is not conducive to a chamber-less cannon. If you want it to work you'll have to get a pressure chamber of some sort. That could even be a short hydraulic hose before the valve. It is possible to switch to a pressure washer valve and that may work with just the remote.
24 February 2008 - 08:15 AMWhen I first built the MCS I brought it out to a team practice. The velocity set screw in my phantom had stripped out, so the gun was shooting all over,unusable.Never to fear the MCS was ready and willing to be used in a pickup game with another makeshift team that had come out for the day.I loaded up on 6 rd shotshells, grabbed my buddies 91 cu in. tank(my tanks were out), and headed out.Game on, saw a guy, aimed fired, poof! The shell landed with the paint in it 20 ft. away.I loaded again... poof! same thing.That's when I caught on.The tank was a low pressure tank.The MCS runs on 800 psi. not 400...
Since I'm never one to back off, I pushed up,firing air.I had a buddy cover me and keep a guy in the last bunker down while I bunkered him with a cannon that wouldn't shoot! Somehow or another just as I rolled around the side of the bunker the guy got hit in the hand by the cover fire.He was in mid word, "hi...oh...sh", was all that got out.Here is a 300 lb. man that is somewhere in between having his hands up in the air,covering his crotch and trying too curl into a fetal position.It was the funniest thing I ever saw.I got up from my crouching position and let him walk away.Only to have one of my teammates come form the other end and try to bunker me! Luckily he didn't shoot.That was a game to talk about.
22 February 2008 - 11:24 PMWell I have done this, albeit it has to be very closely monitored by the reffing staff.My process was simple,adapt a commercial smoke grenade to pull string activation(party poppers), modify an existing shot shell cartridge(my own design),and punch a very small hole in the back of the shell in which to thread the pull string through.From there I tie a knot in the string, load the shell, and finally arm the grenade by inserting the knotted string in a notch located at the rear of the launcher's action(works only for breech loaders).This design achieved a very good success rate and accurately put a smoke grenade anywhere within a hundred foot range.Grenade activation was usuually within 2-3 seconds of firing.Just enough time to hit the ground lit off.
In actual game time I was never allowed to use one.I've only used the smoke to signify special effects or what not.Yes its cool,yes its practical,yes I could use it safely,No I'm not willing to risk my home field getting sued over an accident that could happen.
18 February 2008 - 07:15 PMBlaik has a point.What is your preferred munition? I can tell you from my experience that 1.5" barrels are your friend, when shooting a grenade or shotshell.
If you want short and quick to load take a look at using a pressure washer valve and a break open breach.A pressure washer handle with the proper volume chamber will be fine for grenade launching needs.
And if you need any tips on using that launcher I can help you out.I absolutely love launching grenades.One heck of a power trip! Muwahaha!Seriously, nothing compares to sliding a grenade in a bunker with a fella and laughing as he comes out asking himself, "were did that come from?"
