Sheet goods are too bulky to lift onto my table saw, so I prefer to use my cordless circular saw. I installed a $6 plywood cutting blade, then stuck a hard-board sub-base to the underside of the saw’s base with carpet tape. With the saw immobilized, I plunge-cut down through the hard-board to create a zero-clerarance throatplate.
This is a simple t-square for your circular saw that features a zero clearance base. The base piece should be wider than the distance from your circular saw blade to the opposite side of the base. As long as it sticks up above the base piece by the height of your circular saw base than you should be alright.
