COUNTERS AND TOPS
In cabinetwork, the counters and tops are covered
with a 1/16-inch layer of high-pressure plastic
laminate. Although this material is very hard, it does
not possess great strength and is serviceable only
when it is bonded to plywood, particle board, or wafer
wood. This base, or core material, must be smooth
and is usually 3/4-inch thick.
Plastic laminates can be cut to rough size with a
table saw, portable saw, or saber saw. Use a fine-tooth
blade, and support the material close to the cut. If no
electrical power is available, you can use a finish
handsaw or a hacksaw. When cutting laminates with
a saw, place masking tape over the cutting area to help
prevent chipping the laminate. Make cut markings on
the masking tape.
Measure and cut a piece of laminate to the desired
size. Allow at least 1/4-inch extra to project past the
edge of the countertop surface. Next, mix and apply
the contact bond cement to the underside of the
laminate and to the topside of the countertop surface.
Be sure to follow the manufacturers recommended
directions for application.
Allow the contact bond cement to set or dry. To
check for bonding, press a piece of waxed brown
paper on the cement-coated surface. When no
adhesive residue shows, it is ready to be bonded. Be
sure to lay a full sheet of waxed brown paper across
the countertop. This allows you to adjust the laminate
into the desired position without permanent bonding.
Now, you can gradually slide the paper out from
under the laminate, and the laminate becomes bonded
to the countertop surface.
Be sure to roll the laminate flat by hand, removing
any air bubbles and getting a good firm bond. After
sealing the laminate to the countertop surface, trim
the edges by using either a router with a special guide
or a small block plane.
If you want to bevel the
countertop edge, use a mill file.
METHODS OF FASTENING
LEARNING OBJECTIVE: Upon completing
this section, you should be able to identify the
different types of fastening devices.
A variety of metal fastening devices are used by
Seabees in construction. Although nails are the most
commonly used fastener, the use of staples to attach
wood structural members is growing. For certain
operations, screws and bolts are required. In addition,
various metal devices exist for anchoring materials
into concrete, masonry, and steel.
The increasing use of adhesives (glues and
mastics) is an important development in the building
industry. Adhesives are used in combination with, or
in place of, nails and screws.
Nails, the most common type of metal fasteners,
are available in a wide range of types and sizes.
Basic Nail Types
Some basic types are shown in figure 3-75. The
common nail is designed for rough framing. The box
nail is used for toenailing and light work in frame
The casing nail is used in finished
carpentry work to fasten doors and window casings
and other wood trim. The finishing nail and brad are
used for light, wood-trim material and are easy to
drive below-the surface of lumber with a nail set.
