This is my primary. You will need the following if you wish to complete it.
Tools
Screw drivers
Drill
Fishing wire (at least 10 pound test) Various drill bits.
Pipe cutters
parts
x1 Big Bad Bow (we will refer to it as the 3b for the remainder of the write up.)
x2 Rapid Fire 20 (they will be called A and B.)
x3 screws, about 1 inch long. You need Matching nuts.
x1 3 inch log screw, with a matching nut.
(All NEED to be machine screws, wood screws wont work)
x1 ½ coupler
PLENTY of your favorite barrel material.
Extra spring (for 3b)
First off, open up the guns. Start with the 3b. I have found it useful to tape the outer catch in place on the 3b. This prevents them from annoying you to death closing up the gun. Remove the 3b air restrictor.
Use a dremel (or in my case, gardening shears) to cut off the original 3b barrel. Also, cut out the center of the white thing. Shove some cpvc in there, and fill with hot glue until the white thing.
Take apart the rf20. The first one will be called A. Do whatever mods to A you want. Use the directory. Drill 2 small holes in the shell of A. (the same side that holds the internals) run some fishing wire through the holes (it must be end with the ends outside of the shell.) tie a knot. One end must be long, the other short. Drill a hole in the orange rate of fire selector. Tie the long end of the wire into it. Cut the excess wire. If done correctly, it will allow you to change the rate of fire on A. B, however, won’t have this feature. Place one part of the 3b shell on the other half of A’s shell. Drill two holes. Put the small screws through, and tighten the nut really tight.
Put A together, and close it up. You are now 1/3 done. Good job.
Open B up. Remove the internals and mod as you please. Drill a hole through the shell into the 3b shell. As before, make sure your drill bit is smaller than your screw head. When I drilled I removed the internals.
Drill a hole through B to A. (Be REALLY careful not to hit the internals.) Put B together and close it up. 2/3 done. Here is the hard part. Put the 3b internals in, and close it up. It should look like the first picture.
A's barrels are not straight. It's harder to dodge a wall than a laser.
Every great nerf gun has its own name. The Doomsayer is one of them. I call this Giygas, based on the final boss of earthbound
