yeah, it's a ton of work. if it has been sanded multiple times, it
won't fit together well. i have heard of people running it through a
thickness planer so that it will form a flush surface on top. also,
you will have to scrape the old finish and dirt off of each piece so
they go together tightly. by the time you are done, you might think
the 2 or 3 bucks a square foot you spend on new looks pretty cheap!
