Roger Cook and crew enclose the new spa in veneer stone, while inside homeowner Janet McCue has roped two friends into helping her complete the srtipping and reglazing of the half-round bump-out windows, no small job. The music room recives its final, finish coat of accoustical plaster, and our master carpenter checks out a new four-oscillating-head sander that flooring contractor Pat Hunt is using. Richard visits Kohler, Wisconsin, to see how one company has used computer-aided engineering to design a toilet ""engine"" that meets the challenge of using only 1.6 gallons per flush. Back at the house, Tom shows Steve a flexible molding that bends around the radius of the kitchen bay and matches perfectly with the wooden moldings on the straight runs. Finally, our master carpenter takes measurements for the music room inglenook, making a set of layout sticks he can use in the workshop to accurately reflect conditions in the field.
