How to Cut Birch Plywood How to Cut Birch Plywood
Knowing how to cut birch plywood correctly provides more usable edges and cuts down on wasted material. This in turn will ensure saving money and good material with which to work. Neatly-cut edges also make for tighter fitting joints and less sanding. Although a table saw is recommended for cutting birch plywood cleanly, a skill or jig saw will work equally well if the wood is carefully cut using a metal guide to assist with the cutting. A finish or 80 teeth per inch saw blade will also aid in clean, neat cuts.
Step 1, Plan and Mark Cuts
Lay out the birch plywood on a work bench keeping in mind that these sheets come in 5-by-5 foot dimensions, instead of the conventional 4-by-8 sheets of regular plywood and take up less space. Using a carpenter’s tape measure and marking knife, carefully mark out the cuts required. The sharp edge of the marking guide will provide a cleaner cut when placed against the saw blade and will ensure a more accurate cut.
Step 2, Safety Considerations
Regardless of the cutting tools, cutting plywood produces an abundance of fine dust particles. For this reason it is very necessary to wear eye protection and a dust mask. Cut plywood also produces splinters and therefore it is highly recommended that gloves be worn when cutting it. Gloves will also help to securely hold materials being cut.
Step 3, Cutting Techniques
Attach either a finish or fine-toothed blade (usually 80 teeth per inch) to a table saw or skill saw. If using a jig saw, select a fine-cut blade for this work. Insure that the good side receives the input cutting edge of the saw and that it exits from the secondary side. This will prevent the good face from splintering. Usually a good saw blade will prevent this, but this technique is an added precaution.
When cutting birch plywood on a table saw the procedure is fairly straight forward. If cutting plywood sheets on sawhorses using a skill saw, place the saw blade precisely along the knife-marked line and cut within the line. Allow the waste to drop off the saw horse edge onto a table or work bench placed slightly below it to catch the waste piece. Do not allow the pieces to collapse inward as this will pinch the saw blade and can cause injury if the cut piece jerks backwards.
The use of a metal guide and skill saw will ensure that cuts are perfectly made as long as the cuts are slowly and carefully executed. Simply hold the skill saw securely, placing the saw blade within the markings made by the marking knife. Place and clamp the metal straight edge along the line and rest the skill saw along its edge. Begin the cut, making sure it is exactly along the marked line, and proceed at a steady pace and follow through to the end of the sheet of plywood.
