Circular Saws 101

A good circular saw is a "must have" tool, it will be used for home improvement or renovations and it is the easiest way to cut a sheet of plywood down to sizes manageable on a table saw or bandsaw for your projects. There are many different styles and models on the market,select a style that feels comfortable, I find some very heavy, others have an awkward positioned handle. Purchasing a higher quality model is a good investment, this is a tool that you will use for a lifetime so you might as well get a good one. Don't go cheap on the blade it is not worth having tearout on an eighty dollar sheet of plywood an inch wide on each side of the cut just to save a few dollars.

The first practical portable electric circular saw was invented by Edmond Michel and patented in 1924.

He founded the Michel Electric Handsaw Company to manufacture the saw in partnership with Joseph Sullivan.

The company name was later changed to Skilsaw Inc.

Portable circular saws in general are often referred to as Skilsaws or Skil saws.

Track Saws

track saw

With a table saw's accuracy, a panel saw's capacity, and a circular saw's portability, the track saw makes precise, splinter-free cuts in almost any situation with minimal setup.

Simply lay the zero-clearance 59-inch track on your work-piece and plunge in with the 1,300 watt saw. The track's undermounted friction strips "grab" your stock - no clamping necessary - while the saw slides smoothly on four low-friction glide strips.

Available in both corded and cordless models.

Using a Circular Saw

Always treat these saws with respect, make sure that you have a firm hold on the saw and the material being cut. Position the saw on the edge of the material aligned with the cut mark, start the saw and push it straight into the material. Be aware of where the cord is, it is easy to saw through it. Make sure that you will not be sawing into your sawhorse or bench. Use a sawhorse with a wide top to hold material being cut. Use a cutting box or a cut-off square such as shown below to make accurate cross cuts.

Cut-off Square

cutoff square

This triangle shaped guide allows it to be held to the board with your left hand with room for the saw motor to pass. Make the sides of the triangle about 9" long out of 1/4" thick plywood, the front guide ois a 1" X 3/4" strip about 14" long. Fasten the triangle to the strip with wood screws with the perpendicular edge of the triangle at right angles to the top of the strip. Your first cut should cut through the strip and the end of it is now used as a guide to position the jig.

Cutting Large sheets

Use a Sheet Rack to support the sheet, cut along a straight edge, either make one or purchase a factory made one. Cut on the back side of the sheet with a quality blade for a smoother edge.
