I typically use a table saw but hate running full size sheets across it so this is how I make straight cuts with the circular saw. Simply use a guide to keep the saw straight. My bro picked up this aluminum straight edge at Lowe's for a few bucks. Just make your marks and clamp it down. Of course the guide will need to be offset.
Happy cutting! //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
