2 b marked e 1 and e 2 provide the necessary height to guide and contain the base of the power tools along the length of the guide components 2 a and 2 b slot j shows one embodiment of a means to connect an optional locking mechanism to the underside of the base component 1 fig3 shows the guide rail system in cross section this view is similar to the view in fig2 but slot m in strip 4 and slot a in base component 1 and where they locate are visible fig4 shows the guide rail system form the top in a different embodiment with two side extensions g that sit on essentially the same horizontal plane as base component 1 and connect to base component 1 providing means to reference to the edge of the material f to allow the guide rail to do repeat identical cuts before use the two guide components 2 a and 2 b of the guide rail will be adjusted to the power tool being used by measuring from the location of the power tool blade relative to the power tool base the first guide rail 2 a can be adjusted and locked to the base component 1 by using slots b so that the blade of the power tool will run at the center of slot a the guide component 2 a can be further adjusted with slots b to true straight if desired using a known straight edge or string line and locked there as well the power tool itself is then rested on the top of the base component k 1 and slid against e 1 of the guide component 2 a that is already attached the vertical edge e 2 of the second guide component 2 b is.
