This is only the second project I've done, and I think it turned out great. I modified the measurements so that it fits 3 on each side and 2 on each end, 10 total (but it can seat more; the table is huge).
All I have is a band saw and a drill, and that's all I needed! The legs and support are Doug Fir from HD. The top is all 2x10's that I bought at a lumber yard so that they would have it kiln-dried and have the edges re-sawn. The only 2x10's I could find at the big box stores were green.
I finished it by sanding with 100 grit paper (I read not to over-sand doug fir for staining purposes), stained with one coat of Special Walnut (two coats on the breadboard ends), and 4 coats of satin poly.
This table is a tank. So glad I assembled it indoors, as we would have had trouble getting it in the house after it was all put together!
