Gridlock

With the exception of the end piece of the table yet to be finished, the remaining portion has been divided into 54 pieces (including piece 0 which is not counted). The grid is composed of rectangles that are 20.75" x 16.125". And the end piece(s) are a bit shorter than that. BTW, I have never tried anything like this so much of the actions I am taking are made up on the fly. Any suggestions are appreciated :]
