Old doors make great tables -- they're the right size and shape, and usually made of good solid wood instead of that hollow-core nonsense you find in houses today. The only problem is finding a way to flush out the panels so the surface is continuous and flat. I have seen tables that fill the panels with glass, or cut wood, but I decided to mess around with some concrete instead. You can't use normal Quickcrete in such a thin-set application, but I found that some expansion or anchoring cement (such as Rockite) works pretty well. Throw some modern, angled legs on it, and you've got a sexy little work or dining table.
I salvaged all the wood in this project, but screwed up the concrete bit, twice, so that cost a little bit. Between screws, polyurethane, and concrete, it should run about seventy or eighty bucks.
You will need these materials:
An old panel door, preferably solid wood
4 3'-4' pieces of 2" x 6"
6 24" pieces of 2" x 4"
40-60 lbs of thin-set anchoring/expansion cement
1" drywall screws
3" drywall screws
You will need these tools:
Grinder (optional for polishing concrete or grinding down if you over-fill)
