What's the best 90 degree woodworking joint for limited tools?

Question

I have a woodworking project that requires 90 degree joints. The tools I have available are pretty basic: a circular saw, drill, reciprocating saw, and clamps including a 90 degree clamp. My circular saw can do angles up to 50 degrees.

In the past I've just cut 45 degree angles and glued them together, but for this project I want a stronger joint than that can provide.

What's the best joint to use given these limited tools?

Jeff D · Accepted Answer

A half-lap joint is an easy and relatively strong joint and you can do it with a circular saw.  No angle cuts are required, but you do have to carefully set the depth of the cuts.  If you want something fancier then you could go with a mortise and tenon joint (you can hog out most of the mortise with a drill but you will need a chisel to finish it up).

I agree with Jeff D. I custom make tables and most of the time use mortise and tenon joints. make them a good fit and use some Titebond 2 wood adhesive. No need for any nails or screws if you do this right.

Add screws and or dowels to the 45° joints.

Michael E · Answer

It depends on what kind of joinery you are doing.
You can make dadoes with a circular saw set at a depth less that the thickness of the wood, if you are making shelves.
Similarly lap joints could be made for a corner.
With a drill, you can make a butt joint (not a 45 miter) and use the drill to dowel the joint.

Or you could invest in a hand saw and chisels.
