This hand held sander is a great finish sander. When sanding, grain directions should be the first thing one looks at when deciding which direction to move the sand paper. With the random orbital sander, because of its circular movements, one does not need to take too much notice in the grain direction. Plus, with a velcro pad, switching sandpaper discs only takes a few seconds. Most sanders allow for speed control as well. This is an important feature because you do not want to over or under sand your work since what you leave behind after you finish sanding is going to exist.
Thickness planer. A thickness planer is used to fix surfaces of imperfect wood. If you are picking up less than perfect wood from the lumberyard, wood with some surface defects, a planer will let you fix that wood in the quickest time. A thickness planer pays for itself quick as it allows you to buy cheaper wood that doesn’t have perfect surfaces and fix it yourself. Be careful though. You loose wood during planing. So the remaining amount of wood still has to be worth the price you paid for it.
