Step 1: Making Darts
-Foam Backer Rod. Its found in a hardware store. It looks like the above. A big coil of foam. Try get 1/2"
- Fishing Weights. Ofcourse BB's, old nuts, anything that is small and has some weight to it will work.
-A glue gun and glue.
First, take the FBR and cut a small piece off. Use the glue gun to bore a hole in it. Now that you have a hole, drop your weight in it. Now alll you have to do is cover the hole with hot glue. Don't be afraid to lick your fingers and push the glue down for a better fit.
Repeat this for a good 50 darts and your in business.
Step 2: Modifing the Dart Gun.
-1/2" CPVC (Yes, CPVC.)
-1/2" K&G; Brass Barrel (The best of the best. Found in hobbie shops. They are used for making train tracks.)
I reccomend CPVC. Its easy to find and worksa great. But, if you know of a hobbie shop, get the brass, its amazing.
Now, its simple. Find the barrel(s) that the air comes out of, and get rid of it. Replace it with CPVC or Brass. Remeber, the shorter the barrel, the moer stable it will be, but you may loose some distance. The longer it is, the less stable, etc.
Take a look at the pictures for an example that I did. That gun is called the Night Finder and is 5 bucks in stores. Shoots a decent 50 feet.
Step 3: Converting Water Guns to Nerf.
My water guns shoots a good 150' feet. Its absoultly scary to be honest. These aren't your old nerf gun, this thing will hurt. Alot.
Step 4: Playing With Friends.
Just keep doing it until you have like 15 people to play with. Worked for me, until everyone got bored, but theres always someone else willing to play.
When you do play, wear some eye protection. Sure sounds stupid now, but wait til you see the guns shoot.
Step 5: Learning More.
www.NerfHaven.com - They have lots of modification how to's that are more detailed then mine, and even a home made section.
I take no credit for what I made, I'm no innovator, its all the people at NerfHaven, and other fourms like it.
