DIY Twin Bunk Bed

With the table or circular saw, cut four pieces from the sheet of plywood measuring 9 inches by 37 inches.

Sand all the edges of the cut pieces.

Stand two 2-inch by 6-inch by 80-inch boards on their sides and place one 9-inch by 37-inch piece of plywood at each end. Line the pieces up at each end and hold in place with clamps. Screw the plywood into the 2-inch by 6-inch boards with wood screws every three inches. Repeat on the other end.

Stand the last two 2-inch by 6-inch by 80-inch boards on their sides.Attach the last two 9-inch by 37-inch pieces of plywood with wood screws every three inches, on both ends, to make a second frame piece.

Flip the pieces over and line up one end of the 2-inch by 6-inch by 34-inch board with the ends of the 80-inch boards. Attach the 34-inch board with wood screws every three inches. Repeat at the other end with another 2-inch by 6-inch by 34-inch board. Attach two more 34-inch boards to the second frame piece the same way. This gives you two long rectangle frame pieces with supports at each end for the mattress.

Lay two 2-inch by 6-inch by 48-inch boards on the work surface. Line them up to make an”L” shape and hold in place with clamps. Attach the two boards with wood screws every three inches. Repeat three more times to make four bed legs.

Place one bed frame on the work surface. Place one leg piece on each outside corner of the bed frame. Measure up the legs to 10 inches and make a mark. Raise the bottom of the bed frame to the 10-inch mark on the leg pieces. Secure with clamps.

Drill four pilot holes into the frame through the leg piece, two in each 2-inch by 6-inch board. Offset the holes so they do not intersect each other.

Insert one carriage bolt into each pilot hole and tighten the nut with a socket wrench. Repeat for each bolt.

Measure down three inches from the top of the leg pieces and make a mark. Lift the last frame piece so the top edge of the bed frame is level with the three-inch mark on the leg pieces. Secure each leg with clamps.

Drill four pilot holes into the frame through the legs.

Insert a carriage bolt into each pilot hole and tighten the nut with a socket wrench. Repeat for each bolt.

Attach the last 34-inch board to the outside of the legs as a ladder rung. Measure up from the top of the bottom bunk 16 inches and attach the board to the leg with clamps. Attach the board with 3-inch wood screws every three inches on both ends.

Climb up the side using the bottom bunk as the first step and the 34-inch board just installed as the second step.

Sand the finished bunk and paint or stain as desired.
