7ft Jack-in-the-Box Static Prop

Step 2Frame Construction

Frame Construction
Materials Used:
4 - 2" X 2" X 8' Furring Strips
24 - 1 1/2" L Brackets

Since the box will be quite large (30" x 30") and the plywood is pretty thin, the box is built around a frame using 2" X 2" Furring Strips. Like most lumber, Furring strips are not actually 2 inches, but closer to 1 1/2 inches depending on the type of wood and how dry it is. The strips I had were close enough to 1 1/2 inches, so I went ahead and used that as the size.

The first step is to cut the strips done to size, for a 30" box, you will need a total of 12 lengths. Eight lengths need to be 28 1/2 inches, these will be the top and the bottom of the box. And four lengths of 27 inches, these will be the sides of the box.

The top and bottom portions of the frame will be assembled to form a square, where one end of the length butts up against the length, please refer to the second picture for the proper layout. The L brackets are secured on the inside angles using the screws that came with them.

The 4, 27" lengths (White) are used to connect the top and bottom sections (Blue) together, using the L brackets. When assembled you should have a 30" cube frame.
