Use A Table Saw To Cut A Perfect Circle

Table saws are used for making straight cuts in wood, but with a bit of patience you can use your saw to cut perfect circles too. If you're willing to drill a hole through the top of your table saw, you can start cutting circles with it right away.

Cutting a circle out of wood is usually done with a jigsaw and takes a very steady hand. A router is a more precise way to cut a circle, but it takes some time to set up a jig.

The video above walks through the steps of making a round table.

First, determine the radius of your table or wheel and mark that length from your saw blade on the table. Then drill a hole through the top of your table saw using a 6mm carbide bit. Make certain you are drilling on the side of the saw that doesn't have the motor and check underneath for any other obstructions.

Drop the blade all the way down on your table saw. Then, drill a hole through the center of the wood that you wish to cut and push a 6mm bolt through it. Place the end of the bolt through the hole you just drilled on your table. The wood should now rotate freely around the bolt across the table saw.

Raise the saw blade 3mm and begin cutting by turning on the saw and rotating the wood using a push stick. Slowly raise the blade after each pass until your circle is cut.

If you are not keen on drilling a hole in your saw, you can secure a wood jig to the table and cut a hole in that instead. Always wear eye protection when using a table saw!

    This can be done without drilling a hole through the wood or your table saw (a carbide bit wouldn't work on many table saws anyway). Take two thin sheets of plywood, nail them together using a small panel pin (tiny sharp nail), cut off the protruding end, tape or hot glue one sheet to the wood you want to cut, the other to your table saw and you've got the same as in the video but without damage to either object.
