Materials

The list of materials you'll need is pretty basic, too. Since I have no idea what type or size silencer you're going to build, I will leave the sizes, amounts, and quantities that you purchase up to you. The plans in various design chapters tell you the specific items you'll need for each design, so consult them before you shop.

What I am offering here are basic, generic, and common materials. Like the tools, these are readily available in hardware, automotive, and home-improvement shops. Common caution suggests that you spread your purchases over several stores to avoid suspicion. And if I were you, 1 would not discuss the purpose for your purchases with anyone.

You will need six rolls of black electrician's tape and a roll of duct tape. Get good-quality tape, please. Pass up the bargain cheapie stuff—it's generally not tough, strong, or very sticky. Epoxy is very useful to have as well.

You'll also need lengths of both PVC and aluminum pipe, in smaller sizes, e.g., 3/4-, 1-, and 2-inch. You can make the determinations based on what size silencer you want to build for what caliber gun. The plans in each specific chapter will guide you in this.

Buy either aluminum or copper window screening. It has to be true metal, so don't buy plastic screening. Again, the amount will depend on which plans you choose.

Buy some Chore Boy pure copper cleaning sponges, too. They make great internal packing for silencers.

A selection of the appropriately sized frieze plugs, metal washers, rubber stoppers, and the like will be useful in most of the designs, as you'll soon read.

Need to Know

Clandestine paramilitary operations have given silencers a very sinister image that has been mirrored by our hypocritical entertainment/news media, violent society's pimpmeister. Stripped of personification and man-directed usage, a silencer is simply hardware put to a purpose. A silencer is a sound muffler just like the one on your car's engine.

Until the invention of gunpowder, the hardware and mechanics of both hunting and war were relatively quiet. Victims of war and hunting, human and otherwise, created most of the environmental noise pollution until some Chinese experimenters favored us with gunpowder long before even George Burns was born. The next step was to quiet the explosive noise of gunpowder, a task which attracted no end of experimenters, tinkerers, and engineers. Pioneers include Reade M. Washington and Alfred Capy, who were issued a patent in 1900 for a "muzzle attachment to muffle gunfire." Joseph E. Bissell designed and patented a basic silencer in 1902, while prolific gun designer Samuel McClean turned out four different patented designs in 1905.

The man generally credited with designing the first commercially successful and practical silencer was Hiram Percy Maxim in 1908. Since then, a plethora of designers has marched in and out of the patent office. There is a wealth of historical silencer design technology, by the way, in Don
