Sanding makes everything better.
4x4s and 2x4s for the base. I cut notches out on the longer 2x4s so the cross-pieces (don’t have a picture of this) on the back of the door would lock into place.
I stained the exposed wood with Red Mahogany, and then varnished the whole thing with wipe-on Poly
It’s a very looooong table.
I also think I could have made the proportions look better by cutting down the length of the door/tabletop a little and framing it with 1x3s (like I did with 1x2s on this table).
