I have a powerful drill with a 1/2" chuck, a hand saw and that's about it. I can buy a couple of tools but I really don't want to buy too many things I won't use again. I might get a miter box.
Really don't want to spend more than $40 on materials.

I'm saving to buy a nice table. We moved into a place that doesn't go well for my old round table. I want to make a rectangular one that I can use later in the garage
The biggest problem I see is that I don't have a jointer or planer. I want it to be flat.
