How To Cut Foam Insulation On A Table Saw?

What You Will Need
- A Table Saw
- A Straight Edge Ruler
- Eye, Mouth, And Ear Protection
- A Marker
Step-By-Step Procedure
- The first issue to take care of is measurement. With foam boards, the measurement has to be perfect. Use your ruler and marker to mark the line where you want the cut.
- Note that it’s important that you use an accurate ruler. There are a lot of rulers that lack accuracy. The same goes for in-built rulers in table saws. So, if you’re making something with foam insulation boards that require precise measurements, the ruler has to be precise too.
- Once you’re done with the measurements, it’s time to prepare yourself. It’s mandatory that you wear all protective items before operating the table saw. Cutting foam insulation will generate a lot of dust. So, you must cover your mouth with a mask.
- Use goggles to keep your eyes safe from dust. One last thing to check is to cover your ears with a noise-cancellation item. It can either be earmuffs or headphones.
- Turn your table saw on and guide the board to the blade. Keep your hands away from the blade while maintaining accuracy. Run the blade through the line you made with the marker while measuring. Keep the cut as straight as possible.
- Once the entire board is divided into two pieces, measure them and see if they’re okay. If not, you can make adjustments. Take your time and correct the measurement.
- When you’re entirely done cutting and adjusting the board, wipe the sides of the foam insulation board. This will get rid of any dust residue from the cut.
- Separate the cut pieces and keep them stored in a designated area. With all the mess you’ll make, it can get a bit overwhelming. So make sure to separate the important pieces away from the mess.
- Once you’re done with the whole process, clean the area and get rid of the dust. Also, remove any unnecessary pieces that may be lying around on the floor. Turn off your table saw and keep all the accessories in their places.
