Abstract: An adjustable saw guide for hand-held power saws facilitates a straight-line cut. The guide is adjustable for any width of portable power saw by adjustment and locking of an elongated saw guide member in the proper position on the surface of a saw table slide member which serves as a base of the apparatus.A hand-held power saw rests and slides on the saw table slide member while engaging against the guide member to assure a straight cut.In proper adjustment of the saw guide member for the particular saw being used, the saw (when against the saw guide member) will have its blade just outside and very close to the edge of the saw table slide. This minimizes fraying of the upper surface of the workpiece where the sawblade teeth move upwardly through the surface in cutting.The saw guide apparatus is attached directly to the workpiece by clamps which are adjustable by sliding along a bar. The apparatus may be extended for long or wide workpieces by securing it to another similar apparatus.
