OPERATION
CONSTRUCTING A TABLE EXTENSION
See Figure 68.
You may construct a wood table extension to support larger
workpieces.
 The finished height of the table extension should be
1-3/4 in. The finished length and width should be
27 in. x 14-5/8 in.
 Assemble the pieces as shown. The finished extension
should fit snugly into the rails, and should be level with
the saw table and extensions.
TO INSTALL ThE TABLE EXTENSION ONTO ThE
RAILS
See Figure 69.
Make sure that when you install the table extension onto
the rails, it is level with the rest of the saw table. To do this,
use two 2 x 4 boards that are 55-1/2 in. in length. Securely
clamp the boards to the end of the saw table, and to the
spreader bar.
 Insert the table extension from underneath the rails and
set it into position.
 Make sure the extension lies flat and is aligned with the
rest of the saw table. There should be no space between
the extension and the boards.
 There are holes in the spreader bar. Attach the extension
to the saw with pan head phillips screws and supplied
washers as shown.
