I decided I was going to make this one day, then I thought hey, why don't I make an instructable for it? So here it is!

P.S this is my first instructable. Please comment if you make it! Also please Comment if I should post an instructable for an awesome battle hammer that I made!

Step 1: Materials/Tools

1. Drill. Just any drill will do.

2. Drill bit. Regular drill bit. Just make sure it is the same size as the rivets you will use.

3.Drill bit. Regular drill bit. Just make sure it is the same size as the small end of the bullet shell.

4. Channel locks.

5. Tin snips or gardening sheers or some other
way of cutting sheet metal.

6. Pipe cutter

7. Duck/duct tape (whatever you want to call it!) I prefer duck.

8. Pliers

9. Rivets.

10. Bullet shell. NOT A LIVE ROUND!!! (a bullet shell or casing is what is left over AFTER the bullet has been fired) NEVER TRY TO CUT/DISASSEMBLE A LIVE ROUND-(a bullet that has not been fired/shot) YOU WILL KILL YOURSELF OR OTHERS!!! Something about the size of a 30-30 will work. I used some weird army caliber. You could also use a piece of 1/2in metal pipe if you don't have any bullets or guns, or if you live in the UK.

10. A metal electrical box? I think that's what this is. You could also just make one from scrap sheet metal.

11. Scrap sheet metal. About 3x3in.

Step 2: Cut

Unfold the box and cut the front flap off with your sheet metal cutters. Fold the box back up.

Step 3: Put the Bottom On

If your box has a tendency to spread out then duck tape it so that it won't. Turn your box over and place the bottom piece over the opening. Fold the tabs over so that the bottom stays on. Drill holes and insert rivets and crimp them with the channel locks. Then remove the duck tape.

Step 4: The Chimney

Cut the bottom off of the bullet shell. Then drill a hole in the top of your fireplace and insert the small end of the bullet shell into it. It should be tight enough to stay. You may be wondering why there is a small square of metal on mine that's because I didn't make it tight enough and I had to fix it.

Step 5: Light It Up!!!

Simply put some sticks or paper in and light it up!!! Just keep putting fuel (not gasoline!) in and it can be pretty entertaining!

BE CAREFUL! IT GETS VERY HOT!

UPDATE: Apparently galvanized steel emits toxic fumes when heated so get rid of the toxins by heating it up hotter than it would normally be. You could use a blowtorch or something (maybe put it in a bonfire for a while?).

Anyway, thanks for the comments enlightening me about this.
