Build an 8-ft straightedge to cut plywood and paneling with your circular saw.

Use a circular saw. Place the front edge of the foot against the board, retract the blade guard and hold it in a raised position with your thumb. Turn on the saw and lower the blade into the wood, using the front of the saw foot as a fuicrum. Always wear safety goggles.
Use a jig saw. Tip the jig saw forward on the front edge of its foot. Align the tip of the blade with the cutting line, then turn on the saw and gently but firmly lower the blade into the cutting area. The blade will want to bounce, but by maintaining the firm pressure on the front of the foot you can keep it under control until it enters the wood.
