This is a simple trick to help you make straight cuts on plywood or other wide materials.
I wish I would have learned it sooner, as I never can cut wood and follow a line. This tip is much more traditional and safer than my post on how to cut circles on a table saw.
To cut wood simply, just measure from the edge of the blade guide to the inner edge of the blade.
This accounts for the kerf of the blade – or the amount of wood lost to the cut.
Take that measurement and add it to the distance you need to cut and mark it on your plywood.
For example if I need a 2 foot board and the measurement of my guard is one and a quarter inches, I mark the board at 25 1/4.
I then clamp a straight edge on the mark and measure to ensure that it is even all along my cut.
Then all I have to do is tightly follow my guide and I will cut exactly down the line I need.
Simple right – now in the video I was too busy trying to look good on camera and allowed the saw to move away from my guide which resulted in a wavy cut – that was my fault not the systems…
