For support when cutting long pieces, a work support
extension can be constructed. Fig. 49 illustrates the miter saw
mounted to two standard 2 x 4’s (A). Fasten the four mounting
legs (two of which are shown at (B) Fig. 49) to the 2 x 4’s, using
four screws (not supplied) through the four holes in the
mounting legs. The length of the 2 x 4’s (A) can vary,
depending on the kind of work that will need to be cut.
NOTE: Ensure that the top of the support 2 x 4’s are level
with the miter saw table.
This is critical because the distance from the top of the 2 x 4’s
(A) to the miter saw table varies from saw to saw. In most
cases, standard 2 x 4’s (C) can used. If these are too high, cut
the 2 x 4s (C) to provide this height or use other properly-sized
wood
