You can make your bookshelf any size you’d like, but a standard size with even proportions is about 12 inches deep, 30 inches wide and 48 inches tall. That's big enough to hold books and magazines, but not so big that it won't fit where you want it to. Note: If your shelves are any longer than 32 inches, you'll need thicker lumber or midspan supports so the shelves won't sag when they're filled with books.
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.
