The required list of materials for the BELLOWS is as follows:

4 pieces wood stock 3/4 x 3/4-inches square and 14-inches long.

2 pieces of plywood (or equivalent) 11-3/4 inches long x 6-1/2 inches wide x 1/2-inch thick.

2 pieces of plywood (or equivalent) 11-3/4 inches long x 5-1/2 inches wide x 1/2-inch thick.

2 pieces of plywood (or equivalent) 5-1/2 inches long x 5-1/2 inches wide x 1/2-inch thick.

2 pieces of blackout cloth, AT LEAST, 28-inches long x 13-3/4-inches wide.

3 pieces of paper card stock 14-inches long x 11-3/4-inches wide.

1-16oz can of spray adhesive (or adhesive of your choice).

2-liquid ounces of 5-minute epoxy adhesive (or adhesive of your choice).

hot glue gun and glue sticks (or adhesive of your choice) to assemble the form box.

10 linear feet of REPOSITIONABLE double sided tape in an appropriate applier.

1 roll of CLING type plastic wrap (name brand= Glad or Saran wrap)

The required list of materials for the FRAME is as follows:

8-linear ft. (96-inches) of clear grade, smooth, FLAT, wood, of your preference, 3/4 x 1- 1/2-inches. I prefer kiln dried red or white oak because of the dimensional stability and availability in standard sizes at most lumber and home supply stores.

8-inches of similar wood stock, 3/4 x 2-1/2-inches.

48-inches of similar wood stock, 3/4 x 3/4-inch.

24-inches of similar wood stock, 1/8 x1/2-inch This stock will be utilized for the light dam surrounding the lens board.

6-linear ft. (72-inches) of 3/4-inch aluminum channel. This channel must have an INSIDE dimension of 3/4-inch, and is available in the aluminum stock racks at most hardware and home supply stores.

16-inches of 1/8 thick x 1-1/4-inch wide aluminum flat stock.

16 PANHEAD sheet metal screws, #10 x 5/8-inch in length.

2 CARRIAGE bolts, with 1/4-20 thread, 2-inches in length.

2 short shank RIVITS, 1/8-inch in diameter. Small machine screws, approx. 3/8-inch long, with nuts and washers to match can also be used if you don't have access to a pop- rivet applier.

2 metal WASHERS, with a 1/4-inch CLEARANCE hole, and a 3/4 to 1-inch outside diameter.

4 nylon WASHERS, with a 1/4-inch CLEARANCE hole, and a 3/4 outside diameter.

4 self-tapping studs, 1/4-20-thread, 2-1/2-inches long. These studs will have 1/4-20- machine thread on one end and a self- tapping (screw) thread on the other end.

6 plastic knobs with a threaded metal insert tapped for 1/4-20-thread. Two of these items must be as LOW in height as possible to allow for clearance of the pivoting end frames. The remaining 4 may be of any convenient size for easy gripping and adjustment.

12 inches of thin, flat, spring stock, 1/2-inch wide. I use BANDING material that is used to hold items onto pallets for shipping. Thin, flat, brass or steel stock is also available at most hobby or craft stores in the modeling department.

5 x 6-inch piece of 1/8-inch thick aluminum or plywood to be used as the lens board. This item MUST be perfectly FLAT.

Adhesive of your choice. I prefer quick set epoxy to reduce construction time, but any type of wood glue will work if time is not a factor.

Don't forget that you will need a smooth, FLAT, NON-ADHESIVE surface to assemble the frame components. You will also need enough CLAMPS to hold the pieces in proper alignment until the adhesive sets.
