I was intrigued by this type of flooring and did tape the episode. This type of floor got its start in an industrial setting being perfect for a machine shop. If a piece of work was droped it would not be damaged by the floor. It is imperitive that the wood selected is very old and very dry. A good source is an old barn or other structure that has not be subjected to a great deal of moisture. Another good source is very old pallets. Some very nice wood sometimes gets used in these constructions. Crosscut the wood in 5/8" slices and then a slight bevel added to the face of the "tile". A light sanding will smooth the finished side and make it easier to work with during installation. Note: save all the dust from cutting and sanding to use as the grout of the tiles. Henry adhesive, tile not base cove is as good as any other cement to use. Spread the cement on the floor in a size that you would feel comfortable to work with using 3/8" notched trial. Allow the floor to dry and using a mixture of 3:1 sawdust to lindseed oil mix up the "grout" using a rubber float work the "Grout" into the crevices of the tile. After the "Grout" has dried lightly sand and seal with a good polyurathane.
