How to Cut Thick Wood with Circular Saw [Step-by-Step]

Cutting a thick piece of wood with a circular saw can appear challenging due to the sheer size of the wood.

However, it is possible to master this by following a set of simple steps.

Things You'll Need

  • A Circular Saw.
  • A Speed Square.
  • A Rip Fence (a straight edge or even straight plank of wood is acceptable).
  • A Sacrificial Sheet (MDF or Plywood will do fine).
  • A Capenters Pencil.
  • A Masking Tape.
  • A Hand Saw.
  • Quick Grip Clamps.

Steps to Cutting the Thick Wood with Circular Saw

Begin by placing the thick piece of wood onto the work surface.

A sacrificial sheet is optional in this case as the wood is thick enough to handle the depth of the blade.

Use some masking tape, cover all four sides of the wood before marking on the tape.

The masking tape will prevent splintering of the wood.

After the masking tape is fixed, mark line of cut using a carpenter's pencil and a speed square.

Measure the offset from the edge of the shoe to the blade of the saw.

Transfer the offset distance onto the line.

After the offset is marked, use the speed square and align the saw blade with the mark.

Clamp the speed square onto the wood using a quick grip clamp.

After sawing through one side of the timber, flip the wood piece by 90 degrees..

Using the notch of the first cut, align the blade again and continue cutting.

If the pieces don't separate completely, then use a hand saw to cut the rest of the thickness and free up the piece.

Tips for Cutting Wood Using a Circular Saw

  • Before making any adjustments, make sure the saw is unplugged.
  • Make sure depth is set all the way down before you begin adjusting.
  • While marking, never mark just as a point. Instead, mark it as a 'tick' mark or a 'crow's foot' mark. Doing so helps in identifying the point to be cut easily.
  • Stay away from the saw while cutting.
  • If the piece completely seperates from the wood, let it fall. Never try to catch it while holding a runnning saw in your hand.
  • Never stay right behind or too close to the running blade to avoid injury in case of kickback.
  • Kickback is extremely dangerous and must be prevented at all costs.
  • Using masking tape before drawing the mark on it can help reduce burrs to lend a more pleasing finish.
  • Make sure to cut outside of the line, so the wood piece that you intend to use has the correct dimensions.
  • Use a rasp to clean and smoothen the cut after sawing. Alternatively, A hand sander or sanding paper can also get the job done.
  • Once the saw is turned on, keep it steady but never try to force it back in case it veers off.
  • Using excessive force will create pinch points in the wood leading to damage for both the user and the saw.
