Aside from the power drill, the only other power tool we will use in this book is only used in a handful or projects. This power tool is a heat gun, which is basically a super-charged hair dryer capable of producing temperatures into the hundreds of degrees. Unless you plan to undertake one of the few project that requires this tool, you don't need to worry about it.
Should you use it, remember that it gets hot and should always be pointed away from you. Things heated by it also get very hot. Never heat anything on or near flammable material and keep in mind that it may get your work surface so hot that it discolors.
