Plywood is a versatile wooden product used extensively in the shelving and cabinet construction because it resists deformation and shrinkage. Made of many layers of fine wood heavily pressed together alternating directions, plywood easily supports moisture and temperature fluctuations. When cutting wood, follow these easy guidelines that will protect you from splintering.
Turn the plywood sheet upside down when using your tool for cutting wood. The face of the plywood is the side with the best finish, made for use on the exterior of your project. Because the blade of a saw cuts upward, the thin blades on top are easily chipped.
Lay 2 inches of 4-inch boards under your wood to lift it off the floor. The circular saw cuts lightly on the boards but will protect your ground. Adjust the depth of your saw to extend ¼ inch greater than the thickness of the plywood.
Use another piece of plywood as a guide to keep your circular saw straight if you need cutting help. By placing another piece of plywood and securing it with clamps, you can use the edge as a guide for long, straight cuts.
Keep doing the cut once it starts. Unless there is an emergency situation, maintaining the cut will 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.
Recruit helper when saw cutting wood on a table. Unless you are very familiar with a table saw, simply use a circular saw. A person should stand at each end of the saw and plywood sheet by their outer corners only.
Tips & Warnings
Power saws, no matter how many security features have been installed, are very dangerous. Always follow the manufacturer’s safety instructions explicitly and do not remove safety functions such as plastic protectors.
