A crosscut is a cut made almost at a right angle to the direction of the wood grain, using a tool like a log saw. If you are cutting a tree, the cut made across its trunk almost parallel to the ground is the cross cut. A powered log saw is driven by about a 60 HP electric motor and is fitted with a cross cut tungsten carbide slitting saw blade. You can adjust the length of lumber to be cut using a stopper.

The log to be cut is placed on the V-shaped carriage at about 2 1/2 feet height. The log is held on the carriage and can be swung manually so the fixed cutter works across the log as you move the carriage. You can cross cut the small logs or lumber pieces to required lengths. The log saw can be easily moved, if required.

Step 1 - Mount the Log on the Log Saw

Lift the log and keep it in on the V-shaped carriage for cutting.

Step 2 - Face the End of the Log

Check that the blade is mounted correctly and it will dig into the log when it enters it. Move the log such that its end projects about an inch or more beyond the cutter so the irregular end of log will be cut clean. Use a tooth clamp to hold the log in position. Switch on the saw and move the log towards the cutter to make a cut across the log. Switch off the machine. Adjust the stopper at the required distance (equal to the length to be cut) from the outer face of the cutter with the help of a tape measure and tighten the stopper in this position.

Step 3 - Cut the Length

Move the log to touch the stopper at its end. Clamp the log with a tooth clamp. Start the motor and move the carriage to cut across the log.

Step 4 - Cut the Next Piece

Bring the carriage back into its original position. Push the log to touch the stopper. Clamp the log and move the carriage to cross cut the required length. Repeat this step to cut more pieces till the end piece cannot be held and cut. Keep the end piece of the log aside.

You should use the safety steps recommended for the operation—Use eye protection. Do not run the machine if not in use. Always clamp the log with a tooth clamp to stop it from moving while cutting.
