General Instructions

For pocket hole joinery, avoid placing screws where they will be cut into later.

A larger jig will help with the guard on the circular saw.

Be careful when cutting, it may make sense to clamp the jig as you cut it to keep the jig from rotating while you are cutting.


Step 1

Attach the 1x2 to the 1/4" plywood with glue and fasteners.  Leave a 1-1/2" overhang past the 1x2.

Step 2

Trim the 1-1/2" down to match your circular saw foot by cutting, using the 1x2 as a guide.

Step 3

Find the center point of the 1/4" plywood widthwise.  Then measure down the desired radius of the tabletop and drill hole to match the shaft size of your screw.

Step 4

Attach the jig centered on the tabletop with a screw - I use a 1-1/4" kreg screws.  

Cut obvious excess off with a circular saw.

Then begin cutting using the circle jig, rotating and cutting, repeating until there is nothing left to remove.
