Using a circular saw

If you asked what power tool you need to anchor your workshop I would recommend the circular saw. When it comes to cutting wood I reach for my circular saw 75 percent of the time.

When we were shooting the HGTV show “Room by Room,” we wanted to make sure that everyone watching would be able to complete the featured woodworking project. My motto is: stick to the basics. If that doesn’t work, hire a pro.

I use the circular saw to cut all types of plywood, framing material and even small pieces of trim. If I can’t use a handsaw this is the saw I grab.

If you have never used a circular saw or if you have gotten too relaxed using it, this saw can do lots of damage to wood and to yourself. If you use a circular saw improperly you will remember it for life. Always wear safety glasses. Ear protection is also a good idea.

Here are a few tips for the proper use of a circular saw.

• Setting the proper blade depth is the first step. Proper blade depth will minimize kickback. When cutting a 2 x 4, for instance, unplug the saw and adjust the blade to a depth that leaves the lowest tooth no more than one-eighth inch beneath the wood.

• Always mark the cut line with a pencil and a square. I like to use a roofing square for this and the next step. Guide the saw along the edge of the square. If the saw goes out of line during the cut the blade could bind and the saw could kick back at you. The square also will ensure a nice smooth cut.

• Never lift the saw while the blade is moving. Finish your cut completely through the wood until the off cut drops free.

• When cutting plywood, always support the plywood by using 2 x 4 supports over a pair of sawhorses. This will keep the plywood from flexing during the cut.

• Adjust your blade so that there are just enough teeth to cut through the material. The less blade there is, the less likelihood of pinching should the ply flex.

• Always cut with the plywood’s good face facing down because a circular saw cuts cleanest where the teeth are entering the wood. Use a straightedge to guide the saw. Make sure that you stand to the side of the saw as you cut.

If you are interested in buying a circular saw, go to your local home center store and ask if they are having a demonstration. Don’t be afraid to test drive a saw before you buy one. I have even gone to construction sites and asked the carpenters which brand of circular saw they prefer.
