3-15. Tops are used in all three forms of construction
previously mentioned. Most often, they are large enough
to require two or more pieces of stock to be glued
together. The pieces can be joined with glue, using
various types of joints, such as the tongue and groove.
butt, and dowel. When selecting the material to be glued
together, make the selection so that each piece has
similar grain characteristics, and glue them so that the
grain of each piece has some semblance of matching.
We repeat, the method used to fasten the top to a
cabinet or piece of furniture is an important
consideration, because of the swelling and shrinking of
3-16. In your job, you will probably install laminated
plastics on some surfaces, especially cabinet tops. These
plastics are manufactured in sheets, or rolls, ready for use;
therefore, the only thing you have to do is to install them.
Laminated plastics also come in different lengths, widths,

3-12. Posts or legs used in stool type construction to
support articles such as tables, chairs, and stools are often
milled to decorative shapes, using the wood lathe. Refer
to your blueprint for the size of the posts, and mill them
to these specified sizes and shapes.
3-13. Fasten posts to the rails (see fig. 18) with
mortise and tenon or dowel joints. If mortise and tenon
joints are used, mortise each a side rail, while the other
side receives one tenon of an end rail. If doweled joints
are used, drill dowel holes on the sides in place of the
mortises. When you make mortises or dowel holes, pair
off your posts; in other words, label them left and right.
As you do this, keep the best sides for the face sides.
The face sides are those which will be seen when the
article is assembled.
3-14. Rails, when assembled with posts, form a square
or rectangular-shaped frame supported by the posts.
Your blueprint will give you the dimensions for the
length and width of the rails. The material you selected
must be milled to these dimensions, using the jointer,
planner, and table and cutoff saws. When you cut the
rails to length, add the length of each tenon if mortise
and tenon joints are used. Rails that are fitted with a
panel, as shown in figure 21, must have a groove cut on
the pane edge of each rail.
