Emplaced Machine Gun Design
#1

The design is quite simple. I removed the handle and large purple disc surrounding it,and attached an electric motor and cross member. A button located in the trigger guard (which i attached a large plate to for ergonomics,since the button is quite small) powers the gun. And i attached a 4" bipod to the front end.
Replacment chains were made using Copper pipe and canvas bands,which are expandable with snaps.
Overall the original low fire rate issue is resolved,since the electric motor spins faster than the original crank. The new weapon fires about 3 shots every second. The gun itself weights (with a 9v lantern battery) about 3lb more. So far these are bench test reports. Upon my next battle i'll have my field test summary.

I'd love to see that! Sounds like a solid alternative to posting flyers and newspaper adds for '!!!Nerf Chain Gun Ammo: Will Pay Big Bucks. SELL NOW, MAKE CASH!!!', which actually did work. It just took a couple months, and we only got three replys, but we scrambled together a respectable chain.
If I were you, I'd be worried about that ROF. 3 DPS? That sounds too high for a Razorbeast. Also, if this is going to be an 'Emplaced Machine Gun' as your title suggests, Do you really need a ROF that high? In my oppinion (Which admitedly counts for very little), 1 DPS is sufficient enough to keep people at bay. I'm assuming that since you're using home-made chains that you have rechambered them to fire micros. I am also assuming that since you are using micros, you are getting upwards of 60' in range. I'm also assuming that you're using this outside.
Based on my baseless assumptions, you would not need more than 1 DPS to effectivley halt any rushes, and keep people at bay. A lower rate of fire helps you control shot placement, and conserve ammunition. What actually would be best, is an on-the-fly variable ROF. THat'd be very, very helpful. So when they're rushing, you can blast away at 3 or 4 DPS, and when you've got one or two guys inching their way twoards you, you can put just one or two shots in their direction.
Very nice job though. I love the idea.
Almost forgot: With copper tubing, you must be having some feeding problems with the gun, unless you have an assistant gunner helping you. Take a cue from Starbuck and rig a coat hanger with a piece of copper or PVC as a roller, and atatch that to your gun to take some of the weight off of the advancing mechanism.
All in all, it's a great start. I hope you have fun with that beast (Tee hee... That's a funny pun.)
Sincereley,

LMA the gun gets ten feet spot on,then it starts to drift a lot. But what do you expect with that kind of power? Think original gatling gun VS M60A1 minigun here. There's no comparison in the improvement but the gun itself is still not without it's flaws. As for video....Not happening. my lil brother dropped the video camera skateboarding and smashed it into about 40 diffrent pieces.
Wait... So, are you saying that it's accurate out to ten feet, or it only gets 10 feet of range? Because even for a Razorbeast, 10 feet is pittiful.
I'm surprised that you don't ahve trouble with the advancing mechanism. I'd think that with copper pipe, it'd be a lot worse. Also, I'd advise you to switch to micros. I really like megas, but for a gun with very limited power, and when you're trying to get every last inch of range to match your excellent ROF, micros are a better choice.
If this isn't meant to be particularly mobile, I'd suggest doing what Starbuck did (but didn't take a picture of in his thread). Make a sort of shield. Preferably netting of some kind, that would fit on the gun and give the gunner a fair amount of protection while he's gunning. I think that'd be an excellent addition to your Beast.
