Abstract
Operating a power saw between a pair of parallel guide rails, which engage opposing sides of saw base plate to constrain the motion of the saw to a straight path, allows for precise cuts. A set of two or more fences allows for multiple cutting options. In some embodiments, non-parallel fences coupled to the guide rails allow for precise cuts at more than just a single angle. In some embodiments, two fences may engage opposing sides of the object to be cut simultaneously, holding the object more securely with respect to the guide rails than would a single fence. A possible clamping force holding the two fences against the object allows the miter guide to remain fixed relative to the object so that the user's hand may be freed for another task, such as holding the saw with both hands.
Claims13
A miter guide for a hand-held power saw comprising:
- a first guide rail;
- a second guide rail, wherein said second guide rail is oriented parallel to said first guide rail, wherein said first guide rail and said second guide rail are operable to constrain motion of a hand-held power saw to a straight path by engaging opposing sides of a base plate of the saw, without requiring the saw to be fastened to the miter guide;
- a first fence, wherein said first fence is coupled to said first guide rail and to said second guide rail and is oriented at a fixed angle between 59 degrees and 91 degrees with respect to said first guide rail;
- a second fence, wherein said second fence is coupled to said first guide rail and to said second guide rail and is oriented at a fixed angle between 29 degrees and 61 degrees with respect to said first guide rail, wherein said first fence and said second fence are beneath said first guide rail and said second guide rail, and wherein said first fence and said second fence comprise sides of a substantially c-shaped cross section of the channel;
- and
- a cutting surface, wherein said first fence and said second fence are on said cutting surface, and wherein the cutting surface forms a portion of the substantially c-shaped cross section of the channel, between said first and second fences.
