Mufflers are used as silencers on internal combustion engines. A muffler is installed near the end of the exhaust system of the engine. The noise caused by the exhaust of the engine is silenced as it travels through a resonating chamber inside the muffler. This resonating chamber is designed to make opposite sound waves cancel each other out. Making a muffler for your small engine is a cost-effective way to lessen its noise. All you need are the right tools and some basic skills at welding.

Weld the cut piece of sheet metal to cover one of the ends of the steel pipe.
Drill holes in the steel pipe using the electric drill with a size 4 drill bit. The holes should start from the welded end and should be evenly spaced from each other. Remember to leave at least a 3-inch space from the open end of the steel pipe.
Unscrew the cap on top of the argon gas bottle, using the pliers to grip the cap.
Drill a hole on top of the argon gas bottle. The hole should be the same diameter as the steel pipe.
Drill a hole at the bottom of the argon gas bottle. The hole should be the same diameter as the steel pipe.
Insert the steel pipe, with the covered end in first, from the bottom of the argon gas bottle. Leave a 3-inch length of the steel pipe exposed at the bottom of the argon gas bottle.
Weld the steel pipe and the bottom of the argon gas bottle.
Cut 2.5 inches from the remaining spare steel pipe.
