It may be used on brass or iron pipe, withoutmarking or defacing the same. A sling or a short piece of rope is passed around the pipethree or four times, as shown in the illustration, leaving a shortloop in the middle. Into this loop is inserted a short piece of pipeor a stick far enough to pass the center of the pipe. The looseends of the rope are held tight with one hand, while the short. Fig. 84—Pipe wrench which willnot mar the pipe Fig. 85—A lathe dog as a substitutefor a pipe wrench piece of pipe or stick is held in the other. Now the tighter theloose ends are pulled, the tighter the rope will hug the pipe,and it will be possible to exert quite as much pressure on thepipe with this arrangement as with an ordinary pipe wrench,although this will depend largely upon the strength of the rope may of course be doubled or trebled, according to thesize of pipe to be screwed home. When working on polishedbrass or steel pipes, a little resin may be put on the rope, whichwill increase the friction, or one or more turns around the pipewill answer the same purpose.
