Did you ever need to make a wheel or checkers for your garden checkerboard? With this easy to build circle cutting jig you can go into production in less than an hour!
Step 1: Tools and materials needed
- Table Saw
- Sander or planer
- Drill and Bits
- Countersink bit
- Tape measure
- Straight edge
- Piece of scrap ¾" Plywood or Melamine apx. 18" square
- Good piece of hardwood (I use red oak from old pallets)
- Some scrap wood 1"x1"x6"
- One ¼" x 2" carriage bolt
- One ¼" Washer
- One ¼" Wingnut
- Assorted drywall screws
Step 2: Measure your miter gauge and cut a guide bar
This jig is actually another kind of sled and will ride in the same slot as your miter gauge.
Measure the miter gauge and rip a piece of hardwood to the same width (give or take a few thousanths). Mine is ¾", which is a very common slot size. I used red oak scavenged from pallets for the hardwood. This piece should be at slightly longer than the size of your work surface (which we'll make in the next step). You'll also need another piece about 10" long.
Plane the piece down so it does not protrude above the table top. For me, 3/8" thick was just right. Use a straight edge to make sure it has been planed down enough. Sand off the sharp edges too.
Step 3: Cut the work surface square
Set your rip fence to a convenient dimension and cut your work piece square. Mine was about 18", but that was just the size of the scrap I had. Leave the rip fence in place for now. You can tell the piece is square if you measure across two diagonals and they are the same. If they're not, your rip fence probably needs adjustment. It's really not that critical for this project.
