Hey Pixel
Its a Kayak! Ya I like the Dado Joints, Theres no magic about building this cabinet, everybodys using all these crazy tools and L Brackets. L Brackets; what the
hey are they?

I have found that DADO joints to be very strong and self aligning. Youll never use an L Bracket again. To cut them I set my depth to a 1/4in on my router and run it along a fence (3 dollar peice of angle iron) clamped to the board.
I fact the only tool I usually use to build a cabinet is a router and a four foot piece of 2" angle iron. Although I fire up the table saw for my end panel bevel cuts.
If you use a circular saw to build your cabinet, your making a mistake. There are router bits that will accomplish amazing things.
