Get straight crosscuts and rips with a circular saw
Getting accurate crosscuts and ripping cuts with a circular saw are fairly easy tasks if you take your time, cut at slow speeds and use a guide.
This guide highlights the procedures for operating the circular saw to get straight crosscuts and ripping cuts, along with instructions on how to make a ripping cutoff jig.
WHAT YOU NEED FOR THIS PROJECT
Special squares, like the one shown here, help guide the saw through a short cut. Put the raised edge against the stock and guide the saw along the other edge.
Cutting along the length of the board (ripping) is accomplished with the help of a rip attachment or by clamping a board in place as a guide. The rip attachment, shown here, is fine for making narrow cuts. For cutting wider pieces, make a cutoff guide.
• Make the jig from two strips of 3/4-inch plywood, each 8 feet long. One piece should be about 5 inches wide; the other should be as wide as the saw base plus 5 inches. Have the home center or lumberyard cut them so you'll get straight cuts, then screw them together so that the edges align.
• Guide the saw along the fence piece, cutting the wider piece to width in the process.
• Place the cut edge of the jig along the line and clamp or screw it in place. Guide the saw along the narrower piece to cut along the line.
