ENGINEERED BEAMS

The most daunting part of using engineered beams may be the wide selection. Fortunately, lumberyard staff can usually explain the merits of each type and help you determine correct size. Glulams, or glue-laminated timbers, are the granddaddy of engineered beams. They’ve been used in Europe since the early 1900s. In North America, they’re fabricated from […]

Engineered Lumber

Like any natural product, standard lumber is quirky. It has knots, holes, and splits. And it twists, cups, and shrinks. As mature old-growth timber was replaced by smaller, inferior trees, lumber quality became less reliable—much to the dismay of builders. In response, the lumber industry combined wood fiber and strong glues to create engineered lumber […]

MOISTURE CONTENT

Each day, a mature living tree can pump a ton of water into the atmosphere, so it’s no surprise that logs arrive at the mill with moisture contents of 30 percent to 55 percent. Consequently, a sawmill will rough-cut logs into lumber, air dry or kiln dry it, and then grade the lumber’s moisture con­tent […]

Materials

This chapter of the materials needed to frame and sheath a house. Materials include standard lumber; engineered lumber; sheet materials, such as plywood and particleboard; and fasteners, including nails, screws, and construction adhesives. There’s never been a wider choice of building materials or more readily available information on using them, whether you need to size […]

SLIDING COMPOUND-MITER SAW

A 10-in. sliding compound-miter saw is the ulti­mate tool for a wide range of finish work. The extended crosscut length, combined with adjustable angle and bevel settings, allows com­plicated cuts in larger materials such as 6-in. by 6-in. deck posts, 10-in.-wide siding boards, and large crown molding. POWER PLANERS Moderately priced and incredibly useful, a […]

WRECKING AND PRYBARS

© Disconnect plumbing pipes and electrical cables in areas about to be demolished—and check with a voltage tester to be sure the power’s off. Be methodical and work slowly. Wrecking bars have differing lengths and end configurations. Most are crowbars with crooked ends for better leverage. The longer the bar, the better the leverage. L-bars […]

HANDSAWS

The following inexpensive handsaws are handy to have: Coping saws cut curves into any thin stock, although their primary use is coping trim so intersecting pieces fit snugly. They take both metal — and wood-cutting blades. A hacksaw is most often used to cut metal, espe­cially bolts or nails. Sawblades will last longer if you […]

PLUMB AND LEVEL

A plumb bob takes patience to use, but it’s a compact, accurate tool. The plumbed string is also a useful reference line you can measure out from. The Gammon Reel® shown in the photo on the next page automatically reels in the string so it can’t tangle up in a tool pouch. A 4-ft. spirit […]
