ABSTRACT OF THE DISCLOSURE A POWER SAW FENCE GUIDE A combination mitre and bevel saw 10 is disclosed which 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 plane of the saw blade 26. A spring 72 biasses 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 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. As the saw blade 36 is pivoted about a bevel axis 92 to enable bevel cuts to be made, the fence guide 74, supported on a guide support 62 also pivots about the bevel axis 92 by a corresponding amount. Thus, the fence guide 74 always lies in, and pivots in, the plane of the saw blade 36. It goes without saying, of course, that the fence guide 74 lies in the plane of the blade 36 and, at least in the position A, the blade, on pivotting about axis 28, must not impinge the guide 74. The same is also true of the housing 20 which, in the plane of the blade 36, has an opening permitting entry of the fence guide 74 within the housing 20 when the latter is pivotted downwardly about axis 28. The fence guide 74 permits an accurate estimate of the cut which will be made in a workpiece and also provides for accurate and optimum positioning of the fence members 17a, 17b. 11 (Figure 5).
