ABSTRACT:
A miter saw is adapted for performing lengthwise, or rip, operations on a work piece such as wood. A back support arm is positioned off-center such that the work piece can be inserted under the miter saw substantially parallel to the blade. An arcuate aperture in the back support arm ensures that bevel adjustment properly aligns the blade with the blade slot during bevel cuts. An adjustable rail enables the work piece to be positioned in either a normal position, for crosswise cuts, or an orthogonal position, for lengthwise cuts. A toggle switch overrides the on/off switch on the handle, useful when the work piece is fed from behind. Two separate sleeves cover the blade, assuring safety during operation for both lengthwise and crosswise cuts. A tensioning board feed roller holds the work piece in place during lengthwise cutting.
