With the base cut, you can now proceed to the next step of assembling the crosscut jig for your circular saw.
How to measure and cut the base?
Before you start building your crosscut jig, it is important to measure and cut the base accurately. The base serves as the foundation for the entire jig, so precision is crucial.
Step 1: Gather materials and tools
First, gather all the necessary materials and tools for this step:
- Plywood sheet
- Measuring tape
- Straightedge
- Pencil
- Circular saw
- C-clamps
Step 2: Measure the width of your circular saw’s base plate
Using a measuring tape, measure the width of your circular saw’s base plate. This measurement will determine the width of your jig’s base. Write down the measurement to refer to later.
Step 3: Mark and cut the plywood sheet
Next, use a straightedge and pencil to mark the dimensions of your base onto the plywood sheet. Make sure to include the width measurement taken in step 2. Carefully cut along the marked lines using a circular saw.
