Difficulty: Moderately Challenging
Step1
Turn your plywood sheet face down when cutting with a circular saw. The face of the plywood is the side with the better finish, made for use on the exterior of your project. Because a circular saw's blade cuts upwards, the thin sheeting on top splinters easily.
Step2
Place 2-inch by 4-inch boards under your plywood to raise it off the floor. Your circular saw will cut slightly into the boards but it will protect your floor. Set the depth of your saw to extend ¼ inch deeper than the thickness of the plywood.
Step3
Use another piece of plywood as a guide to keep your circular saw straight if you need help cutting. By placing another piece of plywood on top and securing with C-clamps, you can use the edge as a guide for long, straight cuts.
Step4
Keep cutting once you start. Unless there is an emergency, keep the cut going to achieve a smooth edge. Trying to restart a cut in the middle of a piece of plywood will leave uneven marks on the edge that will require extra filing and sanding.
Step5
Recruit an assistant when cutting plywood on a table saw. Unless you are very familiar with a table saw, just use a circular saw. One person should stand at each end of the saw and hold the plywood sheet by its outer corners only.
