Mark the 1-inch wide edges of four 1-by-2-inch pine boards, 38 inches long, at four places: 7 inches, 11 inches, 15 inches and 19 inches from one end. These boards become the legs of the tower, and the marks become the ladder rungs.
Attach a 15-inch long, 1-by-2-inch pine board to each marked spot with 2 1/2-inch wood screws on two of the four leg boards. The rungs must be flush with the leg boards and now signify the bottom of the kitchen tower.
Attach one of the two remaining leg boards to the open ends of the ladder rungs with 2 1/2-inch wood screws, creating two sets of ladders at the four marks on the board at 7 inches, 11 inches, 15 inches and 19 inches from the bottom.
Slip a 1-by-2-inch pine board, 15 inches long, between the two sets of legs at the open top end, so the 15-inch board is flush with the ends of the legs. Attach these boards to the ladder legs with 2 1/2-inch wood screws.
Connect the two ladders to each other with a 1-by-2-inch pine board, 16 1/2 inches long, at 8 inches from the bottom, using 2 1/2-inch wood screws.
Connect the ladders with 1-by-8-inch pine support boards, 16 1/2 inches long on each side of the tower, using 2 1/2-inch wood screws. Place these support boards so the tops of the boards are 21 inches from the bottom of the tower.
Insert a 1-by-3-inch pine board, 16 1/2 inches long, between the two ladders at the top and secure with 2 1/2-inch wood screws, completing the sides of the kitchen tower.
Lay two 1-by-8-inch pine wood boards, 18 inches in length, flat on your worktable. Set the boards evenly next to each other so the 18-inch long sides are touching, making the kitchen helper tower platform.
Attach two 15-inch long, 1-by-2-inch pine boards, centered in a perpendicular fashion, across the ends of the two platform boards, using 2 1/2-inch wood screws.
Cut two 1-by-3-inch pine boards, 3 inches long, from one corner to its diagonal opposite, using a table saw.
Attach the 1-by-3-inch pine triangles to two 24-inch long 1-by-3-inch pine boards at 3 inches in from each end with 2 1/2-inch wood screws. The triangles become feet for the tower and must be placed on the same side of the 24-inch pine boards.
Attach the 24-inch pine boards to the bottom of the tower, flush with the bottom of the legs, with 2 1/2-inch wood screws.
