*This list is pieces to build one shell and the stand
**This list may be slightly inaccurate
Step 2: Barrel
Make the barrel.
5. Connection for pump slide goes on bottom.
Step 3: Pump
Build the pump. This is a version of the pump used on the OSNJCKMA2, pretty much the greatest gun ever
1. Pump segment
2. Put 8 segments on, spaced with gray connectors
3. Rear of the pump. Pushes the ram rod back
4. Attach the rear of the pump
5. Front of the pump. The ball joint is where the rubber band attaches
6. Sliders. The pump slide goes thru here
Step 4: Breech
The breech of the shotgun (where you load the shells)
1. Top view
3. Some more of the top
4. Add this thing to the bottom
5. Add orange supporters
Step 5: Body
The bulk of the gun.
1. One side of the frame (make two of these)
2. Put them together like this (notice the blue connecting rods and the slight changes on the side facing you)
3. This holds the back of the pump slide. Attaches to the underside of the body
4. Spacer. Holds the sides apart at the bottom
5. Put on spacer
Step 6: Stock
1. The attached butt of the stock
2. Skeleton of the butt
3. Top of the butt
4. Bottom of the butt
5. Connect like so (only top is shown connected. Bottom goes on the same way)
This next part is sorta hard to show because this part of the stock is built into the body.
6. Boundary between the body and the stock
7. Middle of the stock
8. End of the stock
9. Whole stock
11. Underside of front
Step 7: Connect Breech and Body
1. Connect the top
2. Connect the bottom. (shown w/o the orange connectors for greater visibility)
Step 8: Attach the Barrel
1. Side view
2. Bottom view
3. Support. Holds the body and the barrel rigid.
4. Attach to body
5. Attach to barrel
Step 9: Ram Rod
Step 10: Add Pump and Ram Rod
This step is a little tricky.
1. How the pump connects with the ram rod
2. How they both fit into the gun
3. Back of the ram rod
4. The gray rod is the pump slide. It requires a little pulling to get it to connect between its place on the barrel and the one on the body.
Step 11: Trigger
A string trigger. Yeah... I know.......Not very creative. If anyone has a better idea, I'm open to it.
1. The trigger. It works well if you put the string in between the orange connectors.
2. Trigger attaches to the gun
3. Gray rods run up to a block trigger. String ties on to the back (shown w/o the pump)
Step 12: Handle
I don't know if anyone has made this handle before, but if you have, you are hereby acknowledged.
1. Make these
3. Connect to gun. There is a gray connector on the bottom, too.
Step 13: Shell
Main ammunition. To load a shell, just push open one end with your thumb and drop the shot in.
1. The shell
2. The shot
3. A finished shell. The rubber band is to hold the ends closed.
Step 14: Adding Rubber Bands and Firing
Name says it all.
1. Ram Rod bands
2. Trigger bands
3. Bands for the block
4. Bands on the pump
5. How the shell loads into the breech
The ram rod must be pumped before you can push the shell into place. When doing so, swing the shell down into the opening, and the sides should be lifted out of the way by the red connectors on either side, allowing the shot to be lined up in the barrel. To take the shell out, pump the gun and use your thumb to pull up on the black Y clip and swing it up.
If you have two shells, it takes roughly nine seconds to fire two shots.
6. The shell swung into place
Be warned! You will lose green rods when firing this. I suggest you fire into corners in brightly lit rooms to minimize this risk.
Step 15: Stand
An optional step. While I was building the gun, I noticed it was none too good at standing up by itself, so I made this little stand to hold it. Useful for display purposes, or for holding the gun steady while modding it.
Place under the pump.
Step 16: Finished
Congrats! You now have a cool shotgun. Please comment and rate. Also, I think it would be awesome if anyone improved on this. It's sort of a new concept, and it would be great if people developed it.
