Make Dado Joints With a Circular Saw Instead of a Table Saw
Dado Joints are an easy way to join wood together, but requires a precise cut to be effective. If you don’t have a dado blade or table saw, you can still cut the dado joints with a circular saw and a couple of tools.
Dado is a square-walled, flat-bottomed channel cut across the grain of the wood, into which another piece of wood will fit snugly. They are cut using a dado blade on a table saw, which removes the wood to create a channel.
A router can be used to cut dadoes, but a circular saw can also be just as effective. You will need to make two custom rails that are as wide as the edge of the circular saw shoe and the blade embedded in it.
The fences are then clamped onto the wood to be cut and several passes are made with the circular saw to remove the wood. The hammer claw makes the final splitting.
