To conveniently store drywall, paneling, plywood and other long boards, build a second wall out about 2 ft. from a shop wall. Behind this new wall you can store panels, or you can use the space to build shelves as needed to house long dimensional lumber. But build enough shelves for long boards so you don't have to unload a large pile to get to a board near the bottom.
Power drills come in 3 sizes; 1/4, 3/8, and 1/2-in. Size refers to the largest capacity of bit that will fit in the drill's chuck. 3/8-in. drills are the most versatile. They're powerful, yet light enough to easily hold and manage. Larger bits can drill bigger holes, so 1/2-in. drills are best for big, heavy-duty projects. Drills with higher RPM ratings (1200-rpm or more) are better for boring smaller holes into wood. Lower speed models are better at making larger holes into metal.
When sawing wood, take time to consider which side of the material will be facing up. Keep the good side up when you are using a hand saw, scroll saw, band saw or radial-arm saw. Keep the good side down when you are suing a portable circular saw, table saw or sabre saw. The principle is to have the tooth of the blade first break through the rough side of the board or panel.
