This is the DIY plywood or sheet goods cutting table I made. Makes cutting plywood easy. I made it some years back based on an article in Fine Woodworking Magazine. August 2000. It is made to support a sheet of plywood while it is being cut down to size with a circular saw. It is made of four 8 foot long 2×4 pieces of lumber and a pair of banquet table legs you can get at amazon.com 29″BLK FOLDING TABLE LEG (Ebco Tools APF-B)The folding legs make it easy to store when not in use.
This table is sacrificial. This means you actually cut through the plywood into the table. Not too deep! Clamp the sheet of plywood down to the table so it is supported on both sides of the cut. Then use an edge guide to run a circular saw along. The table is 7 feet long, 35″ wide and 31″ tall. You can also use it as a table by putting a piece of plywood on it. I use it as a painting table too. Works great with the Kreg KMA2675 Kreg Rip-Cut. See my review here.
Cut seven- 31 7/8″ pieces for the cross members. By cutting this length, you can get 3 pieces out of each 8 foot length. For the seven foot sides, either use 2x2s or split one of the 2x4s lengthwise. Put cross members at each end and one in the center. Put a cross member 15″ in from each end. This will be the leg support. The remaining two cross members will be the leg lock supports. You will have to determine the position of this by experimenting. Temporarily screw or clamp it until you make sure the legs fold down all the way and lock vertically too. I messed up on this and had to reposition the board. The leg locks hinge towards the top. You pull down on them to lock them. Also make sure you off set the legs a little, so when they fold closed, they do not hit each other.
This table is not a full 4’x8′ like a sheet of plywood, because you only need to support where you are cutting. Use the cross members and sides to clamp to. By keeping the table smaller you can move and store it easier.
