How to make a simple and cheap table out of wood.
First find a source of hardwood pallets. Hey, if you can find another source of free wood or at least cheap wood, good for you. But hardwood is really expensive, and pallets are free. Pine can also work, fir doesn't work well, it's too rough and warps.
Beer and wine distributors seem to be an excellent source of free wood. Sometimes the big box stores also have some.
Be create, sometimes nice hardwood is just thrown away.
The finished table will look something like this.
I ran the wood through a power planner. You could clean up the better side with either a sander or a plane.
