Building a Straightedge Guide for Accurate Plywood Cutting

What You'll Need
Circular Saw
Strips of Plywood
Hand Glove
Safety Mask

Plywood cutting can be done by moving a power tool across the piece of plywood you desire to cut or by moving the respective piece across the tool. Plywood refers to various sheet goods, including fiberboard, laminated veneer core, lumber core and particle board, and it can be found in a raw as well as a well-coated form. As plywood is a somewhat flexible material, it often requires building up of a straightedge guide for accurate cutting. You can follow the simple steps below to build your own guide for cutting plywood.

Step 1: Cut Strips

Place your foot board of plywood on top of your respective saw horses. Proceed by marking several points a foot away from the border. Use your level to construct as straight a line as possible through these points. Now, use your circular saw to cut through the line you have made. Fashion a 1-foot band of plywood to create a 3-inch strip from the other corner of the original board using the same method.

Step 2: Position the Strips

Once the strips have been cut, place them in such a way that the 3-inch strip lies over the 1-foot strip and that the edge of the cut 3-inch strip comes in line with the original border of the longer strip. In effect, once the positioning of the strips has been done, the original border of the shorter strip should formulate a fence on top of the bigger board with about 9 inches of plywood left in the front. Once this positioning has been done, place screws all over the board positioning them after every foot or so.

Step 3: Place your Saw Right

Once you are through with the positioning, stand towards the far end of your boards in such a way that the smaller one stands on your left. Then place your circular saw on the bigger board’s border with its blade falling in the front. The board should be towards the right side of your saw whilst the edge of the flat saw is butted up against the machine. Also ensure that the blade of your saw is within the right side of the bigger board.

Step 4: Create your Guide

Once your machine is set appropriately, start your saw and run it over the boards using the shorter strip of plywood as your guide. The circular saw should give you a perfect cut which is not only straight but which runs through the wider board neatly and accurately too. See to it that you are using safety measures like wearing hand gloves and safety masks during this step and the next.

Step 5: Use the Guide and Cut Through

Fasten your newly established saw guide to the wood you will cut. Bring about the edge of the larger strip of plywood with the line you wish to cut through, and place the guide itself towards the line’s left part. Now lower down the blade of your saw so that it clears out the shorter strip of plywood along with the wood that you have placed beneath it. Keep the blade hanging toward the right side of the fence. Push the blade through and run the saw along your guide
