FUNNELS. A three-piece pack of funnels I bought cost $2.19. After a shop discount, each funnel cost me about 50 cents.
To make the mouthpiece,
• Mark the funnel about 1½” from its narrow opening.
• Place the funnel on a flat surface.
• Hold the funnel with your left hand and cut it on a plane parallel to the flat surface using a thin saw.
• Rough-smooth the cut edge on a disk sander or rub it on sandpaper laid flat on a table.
• Check the fit in your mouth. Remove material as necessary.
• Smooth the edges with fine sandpaper.
• Insert the pipe into the stem of the funnel.
• Remove material as necessary.
If you want to fix the funnel to the pipe, apply glue inside the stem then insert the pipe. Make sure to remove excess glue. However, if you shoot in the field, it will be easier to transport a blowgun without its mouthpiece. In this case, do not glue the funnel to the barrel. When you shoot, attach the funnel to the barrel. When you finish shooting, pull it out.
PLASTIC PILL CONTAINERS OR SOFT DRINKS BOTTLES. Pill containers or the neck of a soft drink plastic bottle can be fashioned into mouthpieces. You can even contour the mouthpiece to fit your cheeks. You might need to wrap several layers of electrical tape around the pipe to increase its diameter to fit the mouthpiece.
GRIP
The outside diameter of a .40 caliber commercial blowgun is about ½-inch which is too small for a shooter who has big hands. For this reason, most commercial blowguns are provided with a foam grip. The grip will allow a secure and comfortable hold on the blowgun and will
prevent your hand from freezing onto the barrel should you decide to shoot your blowgun during winter.
The .625 caliber Magnum blowgun is not provided with a foam grip. However, you can wrap foam around the barrel then duct tape it to form a grip. You might be able to find a discarded garden hose that could fit the outside diameter of the barrel or bamboo with the right inside diameter to fit your blowgun.
MUZZLE PROTECTOR
The blowgun needs little maintenance. However, if you are to shoot with consistent accuracy, it has to be kept in good condition.
Commercial blowguns are provided with plastic muzzle caps that prevent the aluminum pipe from getting dented. A homemade blowgun can be protected in the same way.
A number of materials can be used to protect the muzzle of your blowgun. You can use any short length tube of rubber, plastic, or wood. The muzzle protector should extend about ½-inch past the lip of the muzzle, must be rigid, and must not interfere with the smooth exit of the dart.
A short length of bamboo (tube) can be used as a muzzle protector. The bamboo tube has to be constructed such that it cannot slide too far in and expose the tip of the muzzle to possible damage. To imitate the construction of the commercial muzzle protector, use a conical grinding stone to enlarge the bore of the bamboo tube at one end.
COUPLING
A long blowgun can be made from several short lengths of pipe. This will allow you to have a long-barreled blowgun that can be assembled and disassembled in the field, thus making transport less difficult.
Ease of transport is not the only reason for a takedown version. A takedown version is also required should you use PVC pipes to make a blowgun. Long pipes made of PVC will bend due to weight. To make a blowgun of the desired length from PVC, you will need two or three short pieces which you can join using a coupling.
A coupling can be metal or wood with an inside diameter that matches the outside diameters of short tube sections. It is used to connect two short tubes to make one long tube. Where the two tubes meet the joint must be seamless or nearly so to ensure the smooth travel of the dart.
Commercial two-piece blowguns come with plastic couplings. You can make a three-piece blowgun from two two-piece blowguns. In this way you can make a 7-foot blowgun that you can assemble and disassemble in the field. However, such a 7-foot blowgun will have an unavoidable curve. Despite the curve, with some practice, you can still have a good shooting average.
A coupling need not be made of metal. For example: Indonesian, Malaysian, and Philippine two- and three-piece bamboo blowguns (Figure 1-1) use bamboo with a bigger diameter as coupling. The two-piece bamboo blowgun has one piece measuring 25½ inches and the other 27½ inches but with the overlap its overall length comes to 49½ inches. The three-piece blowgun consists of three 22½” sections that give the blowgun an overall length of 62 inches.
Blowgun master Dr. Hironori Higuchi uses couplings made from rolled plastic films (Figure 3-13) on three-section aluminum blowguns. The coupling can easily be slipped over the aluminum tube. A “quick and dirty” coupling using the same idea can be made from thicker-than usual paper.

MAKING YOUR OWN DARTS
Commercial .40 and .50 caliber darts come unassembled. The .625 Magnum darts come assembled. Their tails will not last indefinitely. Their collapsible flanges will eventually rupture. Hence, you will end up with shafts with no tails. You can save the shafts to make your own darts.
