How to Make Your Own Choir Risers
- 1). Lay two 80-inch boards on edge, parallel and 21 inches apart. Set five 21-inch boards between them at right angles and space them 14 1/2 inches apart. The sides of the two outside 21-inch boards are flush with the ends of the 80-inch boards. Screw the 80-inch boards to the ends of the 21-inch boards. Use three screws for each end of the 21-inch boards. This is a frame for one riser tier. Repeat this step two more times to build the frames for two more tiers.
- 2). Set two 80-inch boards on edge, parallel and 21 inches apart. Set two 21-inch boards between them and space them 77 inches apart. Screw through the 80-inch boards and into the 21-inch boards. Use 12 screws for this task. This is a support frame for the bottom for one of the tiers. Repeat this step two more times to build the rest of the supports.
- 3). Position two supports on top of each other so the sides are flush and set one of the tier frames on top of the two support frames. Set a 16 1/2-inch board inside each corner of the frames and screw four screws through each corner on each frame and into the 16 1/2-inch boards. This is the back riser frame.
- 4). Lay one support frame flat and set a tier frame on top of it so the sides are flush. This is your middle riser. Position an 11-inch board inside the corners of these frames and screw four screws through each corner of each frame to secure these boards.
- 5). Position the middle riser against the back riser so the 24-inch sides are flush. Screw through the 80-inch boards on the middle riser and into the back riser. Use 12 screws for this task. Position the last riser tier frame against the middle riser so the 24-inch sides are flush and screw through the 80-inch board and into the middle riser using six screws.
- 6). Set a sheet of plywood on top of each tier frame so the edges are flush. Screw each sheet of plywood to the frames using sixteen screws for each sheet of plywood.
