I am going to show you how to make a flame thrower pistol with easy-to-change ammunition canister!
Step 1: Step 1: Make the Frame
All the materials: Wood (see below), screws, a spring, a nail or similar, a dremel tool with a cutting wheel (a chisel can also be used but I prefer a dremel), a drill, screwdriver and sanding paper (optional).
First you are going to need a plate of wood, preferably a composite with 5 layers, about 1 cm (0.3 inches) thick, and a 4 cm (1.5 iches) by 6 (2.3 inches) piece of wood, and 4 wooden screws about 4 cm long and 2 screws about 2 cm (0.7 inches) long.
Cut the as following:
Step 2: Step 2: Make the Trigger Mechanism
Now we want to make the trigger. Using the wooden plate, cut an l shape about 20 - 25 cm long and the shorter end about 8 cm long and 2 cm wide. Drill 2 small holes: The first one in the corner and the second a little longer down. The holes should be about the size of a nail.
Step 3: Step 3: Attaching the Trigger Mechanism
Now flip the frame from step 1 so that you can make a square hole about 1 cm wide and 4 cm long in the middle of the top plate. (I used a dremel to cut it but you can use whatever you want). Then drill a hole along the black line (under). Then put the trigger mechanism you made in step 2 trough the hole and run a nail or metal rod through the hole you just drilled and through the second hole in the trigger mechanism. Then attach the spring to the back screw head and to the first hole.
Step 4: Step 4: Make the Hairspray Canister Holder
This part can be a little bit tricky, as you have to measure and make sure the canister fits snugg.
First, make another L shaped piece of wood from the wooden plate that is almost the length of the hairspray can. The shorter end should be a little bit longer than the hairspray cans bottom diameter. Drill 2 small holes and attach it to the square piece of wood with the 2x 3 cm screws.
Attach the can using the little ledge on the top and forcing it into place. The harispray have to be flamamble and one of those cheapy ones with the standard canister size. (It should be a little hard to attach, if its not the canister may fall out while moving. Also now when you are done with all the wooden parts, you can sand them down to make them more comfortable.)
Step 5: Step 5: Make the Ignitor
This is the last and easiest step. Take a nail or a metal strip about 10 cm long and bend the end in a 30 degree angle. The little piece should be about 2 cm long. Take a piece of a rag and wrap it around the bend and secure it with a zip tie. (The rag have to be replaced a lot of times since it burns up.) Secure the metal strip or nail to the end of the trigger mechanism and you're done!
