Well I happen to have a table saw and a router, and I guess it would be used for smaller joints, like maybe drawer size, up to around a foot and a half. I wanted to finger joint a box like i did in my underseat storage compartment. I was going to try and dovetail a bench together with no other brackets or supports, but this would be with material 1 3/4" thick material. let me see if i can find you pictures of what I am looking to do to learn these joints.
This picture is the storage boxes I made, and I would like to have finger jointed them.
This is a sample of a bench that i found searching on the internet, I would like more dovetails than this, but this is the structure of what I had in mind. I also plan on using an old piece of cypress and cutting it into 3 pieces.
