 +
 +===== Cheater Bar =====
 +
 +Cheater bars are usually used to break free threaded pipe, screws, bolts, and other fasteners too difficult to remove with a ratchet or pipe wrench alone. \\
 +They are also commonly used to operate valves. ((https://​en.wikipedia.org/​wiki/​Cheater_bar)) \\
 +
 +The cheater bar allows higher torque with the same force by: \\
 +torque = radius × force \\
 +
 +A cheater bar (snipe, a pipe extension or an extension pipe) is slipped over the handle of a wrench to extend the length of the handle. \\
 +The extra length adds leverage and allows you to pull with the same force to add extra turning power to the wrench. \\
 +A cheater bar is generally not needed while using a torque wrench on a Sportster. \\
 +The wrench itself is designed for the intended torque range that it works in. \\
 +There is change of torque applied to the wrench if using a cheater bar on it. \\
 +You will lose '​feel'​ when using one. If using it on a clicker wrench, you can easily over-torque before the wrench clicks. \\
 +Avoid using a cheater bar on a torque wrench unless it's necessary. \\
 +The bar over the end can move the set value on a clicker wrench while you're using it. \\
 +
 +**Problems with using cheater bars**: ((https://​en.wikipedia.org/​wiki/​Cheater_bar)) \\
 +OSHA, MSHA, CCOHS, EU-OSHA, etc. strictly prohibit or discourage the use of cheater bars due to the extreme risk of injury or death to users and bystanders. \\
 +If the component frees suddenly, you can become a projectile propelled into whatever is in the "​line-of-fire"​. \\
 +This could (and has) resulted in falls, impacts, punctures, and other injuries. \\
 +The cheater bar itself can become a catapult. \\
 +Heat is produced whenever a bolt is tightened or loosened. The faster you turn, the more the heat. \\
 +A cheater bar can quickly heat (or overheat) a fastener or the opposing threads where the fastener resides. \\

 +===== Breaker Bar (pull handle) =====
 +
 +A breaker bar is a lengthy, non-ratcheting tool intended for use with sockets. It works on the same principle of length as a cheater bar. \\
 +The primary function of this long tool is to generate more torque than a standard socket wrench when you apply the same amount of force. \\
 +Breaker bars can range from 10"​-38.5"​ in length. \\
 +These tools are useful for turning sockets and loosening any nuts and bolts that are tight or have become stuck.
 +They are much more safer than a cheater bar.

 +
 +===== Double Wrench Method =====
 +You can wedge a bigger open/box end wrench on a smaller one to gain extra leverage. \\
 +This works on the same principle of extending the pull point for extra length/​leverage.
 +Caution: The leverage wrench can slip with busted knuckles or other injury to follow. \\
