President Bush's Oval Office features the same cane-back armchairs that have been kept since the Hoover administration. To make the copies of the chairs for the replica, eight tiny pieces of wood had to be fitted together to hold the nylon screen that gives the cane effect. Working on this scale requires the tiniest of tools. A drill bit of .016 is frequently used, but it is so thin it can hardly be seen. Staining the wood is almost as difficult as making the furniture; a drop of stain looks like a tidal wave when working on such tiny pieces. The cushion is made of bass wood, painted with a flat, water-based paint to give the appearance of upholstery. Oil paints are used to produce the shiny effect, as on the telephone, which has a light that really blinks.
