A combination mitre and bevel saw 10 includes an elongate fence guide 74 operatively connected to the saw blade assembly 20 and pivotable between a retracted position and an extended position in the plan of the saw blade 26. A spring 72 biases the fence guide 74 into its retracted position. The fence guide 74 may be pulled down by the saw operator into its extended position so as to indicate the position at which the saw blade 36 will impinge upon the workpiece and so as to allow the setting of two fence members 17a, 17b accordingly. The fence guide 74 includes a leading edge 78, which indicates the width of cut which the saw blade will make in the workpiece and a wider portion 80, trailing the leading edge 78, which indicates the optimum spacing of the fence members 17a, 17b.
