You can find power tool accessories at retail stores, on the internet, and at home improvement stores. You will need to purchase accessories that match the brand of power tool you purchased. It is a good idea to have the model number ready when you purchase power tool accessories, especially if it is an older model. Higher grade numbers mean the paper is finer. To cut your time down, start with a very coarse sandpaper. As you are about to complete the project switch to finer sandpapers to give you a great finish. Make sure you use the right type of sandpaper for the material you are working with. Sandpaper is very inexpensive so it is a good idea to buy a variety of grades and types to have on hand. If it is having difficulty, back it out some and then proceed slowly. You can damage the drill and cause injury to yourself it you attempt to drill a larger hole then the drill is capable of completing. Always wear safety glasses or goggles when you operate any type of drill. Always unplug the drill before you change the bit in it. Practice on something before you use one on a project to get a feel for it. Saws are a well used power tool. Most anything that is build with wood involves using some type of saw. It can be to cut the beams or to cut corners and holes in the middle of the wood without touching the edges. Saws are also one of the most dangerous power tools out there because of the sharp blades and the shear power they have. Routers can be frustrating at first, but don t be discouraged. Practicing with a router will show you exactly what it can and can t do. Make sure you don t move the router too slow or you can burn the area you are working on. It can also make your bit very dull. Moving the router too fast is dangerous as well because your work with be rough and you will likely break your bit. Heavy duty work gloves are good to have if you are working with any sharp objects including sheet metal. A full face shield will protect even more when you are using certain power tools. The proper clothing is very important too. It is a good idea to wear long sleeves to prevent burns and cuts, but make sure that the clothing isn t too loose.
