Cheater bars, sometimes called pipe extensions, are a way for you to increase your leverage on any wrench. Cheater bars are usually used with socket wrenches, breaker bars or torque wrenches to tighten and loosen nuts that must be torqued to 150 to 500 pounds. Torque is always measured at the nut, so the longer the cheater bar, the less force a mechanic has to apply to tighten a nut to a specified torque or to get that nut off again.
Measure the length of your Crescent wrench handle and multiply the measurement by 2.
Measure that length from one end of a piece of ductile iron or steel pipe using a steel tape measure. For example, if your Crescent wrench has a 12-inch handle, measure a 24-inch length of pipe. Mark the end of that measurement on the pipe with masking tape.
Tighten the pipe in a bench vise, leaving the section marked with tape out of the vise jaws. Cut the pipe to length with a hacksaw. Remove the pipe from the vise.
Slip the cut section of pipe completely over the handle of the Crescent wrench to double the leverage you can apply to your Crescent wrench.
