Technique for Ripping Plywood

When mass producing 16" wide strips of plywood - or a sheet of OSB divided into 3 strips - the technique is to cut right from the full pallet of OSB. A full pallet (brick)weighs about 1.5 tons, and it is shaped like a cube. In this form, all the edges line up. To divide into 3 strips:

1. Use a 6" screw and connect the top 12 layers together for cutting. Use 2 screws, one at about 16.5" on the 4' side, and another one opposite. This will prevent the OSB from twisting on you, since the 12 layers weigh over 500 lb and will not shift when acting as a monolithic block because they are screwed together.
2. Take a circular saw - corded preferably due to batteries running out - and with a 16" edge guide, cut one side. Then cut the other side. A typical 7-1/4" saw may cut 4 layers at one time.
3. Once cut, remove the 2 outer strips - 8 strips total. Note the middle strip is screwed down. To free the screw - just drill further through 2 inches - thus use a drill bit of 2" length. This libear
