The Doc Sarvis Silencer

There's more to cardboard than cartons and more to screens than windows and doors. That's why our in-house shaman, good old Doc Sarvis, came up with this simple silencer made of PVC pipe, corrugated cardboard, and screening.

To construct this one you'll need about a foot of PVC pipe (1 1/2-inch inside diameter), a piece of aluminum or bronze screening (about 5 inches by 40 inches), a couple of hose clamps, electrician's tape, some cardboard backing sheets or a small carton, a 3/8-inch by 10-inch piece of wooden dowel, and some epoxy glue.

Doc's first step is to make two electrical-tape

bushings for the barrel of the soon-to-be-silenced weapon. He says to start one at the muzzle and the second about an inch and a half back from that. Make these bushings big enough so that the barrel will just barely slide into the PVC pipe.

Then Doc says to cut out twenty-five 1 1/2-inch cardboard washers from the heavy cardboard, drill or punch a 1/4-inch hole in the center of each, and glue five of them into one end of the PVC pipe. Set the other twenty aside for a moment.

Cut a piece of screening to 1 1/2 inches by 36 inches and wrap it tightly around the wooden dowel. Insert the dowel into the PVC pipe and slide the roll of screening in until it comes to rest against the five cardboard washers. Remove the dowel.

Next, insert the remaining twenty washers into the PVC pipe up to the rolled screening. Do not glue these in place. Then Doc says to tightly roll a piece of 3-inch by 36-inch screening around the dowel as you did before and insert it into the PVC pipe.

Align the silencer with the gun's bore by inserting a .22-caliber cleaning rod into the bore of the weapon, being certain a foot or so is sticking out the end of the barrel. Carefully slide the silencer unit over the cleaning rod and onto the gun, with the open end going back to the rear bushing.

When you tighten the unit down on the weapon with hose clamps, be certain the silencer stays aligned with the bore. If the cleaning rod moves easily in and out of the bore and unit, the alignment is OK. Doc also says it would be a whole lot safer if you remove the cleaning rod from the bore before you fire the weapon.
