TWO WAYS TO SECURE A TOEKICK

Posted by on 21/ 11/ 15

As you install each cabinet, first transfer the stud center marks to the mounting rails on the back of the cabinet. Then drill through the marks, using a bit that’s thinner than the shanks of the mounting screws— or a countersink bit. Drill slowly to avoid splintering the plywood on the inside of the cabinet, or stop the countersink bit just as its point emerges. Then finish drilling from the other side.

Подпись: Once you've leveled all the toekicks in a cabinet run, screw them to the subfloor. If you use square- drive screws, the driver bit is less likely to slip out when the screw meets resistance. Подпись: If a floor is badly out of level, avoid using a stack of shims to level a unit because they wouldn't be stable. Instead, use plywood ell-supports: Screw one leg of the ell to the subfloor. Then screw the leveled toekick to the other leg. 1111

Подпись: Once you've leveled the toekicks along a wall, start setting the base cabinets on top, and check them for level as well. If the cabinets are in an L- or U-shaped layout, work outward from a corner. Setting cabinets with integral toekicks. If

your cabinets have integral (built-in) toekicks, be sure to review the preceding section on rough toekicks. Shimming units with integral kicks is similar, but more difficult. Basically, you’ll shim each cabinet under its sidewalls, front, and back...

INSTALLING BASE CABINETS

Posted by on 21/ 11/ 15

Cabinet installers wrangle about whether it’s easier to install base or wall cabinets first. If you hang the wall units first, you won’t need to lean over the base cabinets as you work. Whereas if you install the bases first, you can brace the bottom of the wall cabinets off the bases and thereby install the uppers single-handedly.

There isn’t one right answer, but the photos on p. 318 make a convincing case for hanging the wall cabinets after installing stone countertops. Above all, be patient. Setting cabinets means endlessly checking and rechecking for level, fussing with shims, and so on. So don’t begrudge the time it takes. You can’t hurry love or cabinets.

Efficiency of the Monte Carlo algorithm

Efficiency of the Monte Carlo algorithm Подпись: (6.71)

Referring to Monte Carlo integration, different algorithms yield different esti­mators for the integral. A relevant issue is which algorithm is more efficient. The efficiency issue can be examined from the statistical properties of the esti­mator from a given algorithm and its computational aspects. Rubinstein (1981) showed a practical measure of the efficiency of an algorithm by t x Var(©), with t being the computer time required to compute ©, which estimates ©. Algorithm 1 is more efficient than algorithm 2 if

If the computational times for the two algorithms are approximately equal, comparison of efficiency can be made by examining the relative magnitude of the variances. When the true variances are not known, which is generally the case, sample variances can be used...

Insulating between floor joists in crawl spaces

Posted by on 21/ 11/ 15

Floor insulation is important in a house with a crawl-space foundation. Often, it is not enough just to put insulation under the floor, because cold can pass through the rim joist. Unless batts fill the entire joist space, cold air can seep in through the rim joist and over the top of the batts, making the floor uncomfort­ably chilly.

To prevent this from happening, you can either hold the insulation high or roll it up to cover the rim joist (see the top illustration on p. 206). Better yet, use a thicker batt with a higher R-value to fill the entire joist space and butt up against the rim joist.

When insulating between I-joists, make sure the insulation is wide enough to extend all the way from web to web...

Single-Support Installation

Posted by on 21/ 11/ 15

The correct installation of sign-support assemblies is dependent upon the type of sup­port post, the type of soil present, and the impact performance design of the sign assembly. Installation instructions are contained in standard state drawings and, for proprietary devices, from signpost manufacturers. Proper installation practices for the most common types of single support assemblies are presented in subsequent sections.

U-Channel Posts. The most common method of installing U-channel posts is by direct burial. The burial can be achieved by mechanical post drivers, by sledgehammer, or by digging a hole and backfilling. If the post is to be placed by driving into the ground, then a driving cap should be used to prevent damage to the end of the U-channel...

Water Treatment Equipment

Water Purification in Standard Construction

Poor indoor air quality is not the only form of pollution that affects human health. Our water sources, both public supplies and pri­vate domestic wells, have also become increas­ingly contaminated. Public concern about water quality has increased dramatically. In late 2005, the Environmental Working Group (EWG) found in an analysis of more than 22 million tap-water quality tests (most of which were conducted to meet EPA compliance) that 260 contaminants were detected in water served to the public.1

Of the contaminants identified in the EWG study, the EPA has set enforceable health lim­its for 114 contaminants and nonenforceable, recommended standards for five...

Safety on the Job WORKING WITH FIBERGLASS INSULATION

Safety on the Job WORKING WITH FIBERGLASS INSULATIONSafety on the Job WORKING WITH FIBERGLASS INSULATION

GLASS FIBERS CAN irritate your skin and damage your eyes and lungs, so safety precautions are very important when working with fiberglass insulation. Cover your body with a loose-fitting, long-sleeved shirt and long trousers, and wear gloves and a hat, especially while insulating a ceiling (see the photo below). It’s best to wear a pair of quality goggles, too, because eyeglasses alone don’t keep fiberglass particles out of your eyes. Make sure the goggles fit properly; goggles that fit well don’t fog over. Wear a good-quality dust mask or, better yet, get yourself a respirator. Don’t scratch your skin while you’re work­ing (you’ll just embed glass fibers), and be sure to wash up well when you are finished.

Cutting Batts. Cutting fiberglass batts to size is straightforward...
