Things You'll Need:
- Four pieces of 41-1/2-inch 2-by-6
- Four pieces of 75 inch-2-by-6
- Four 68-inch pieces of 2-by-4
- Four pieces of 41-1/2-inch 2-by-4
- Four pieces of 75-inch 2-by-4
- Eight pieces of 38-1/2-inch 2-by-4
- 16 3/8-inch carriage bolts 3-1/2 inches long
- 16 3/8-inch washers
- 16 3/8-inch nuts
- Two sheets of 3/4-inch plywood 38-1/4 inch by 74-3/4 inch
- One pound of 3-inch deck screws
- 3/8-inch wood plugs
- One pound of No. 10 finishing nails
-
Step 1
Build a rectangle with two pieces of the 75-inch 2-by-6 and two of the 41-1/2 inch. The 75-inch boards should be in between the 41-1/2 inch boards. Screw them in at the corners using three wood screws and cover the screws with the wood plugs. Repeat this for the second set of 2-by-6 boards.
-
Step 2
Place four pieces of the 38-1/2-inch 2-by-4 in the middle of the rectangles. These will be the support beams for the beds. Space them evenly with 18-3/4 inches between them. Screw them to the rectangle using two wood screws on each side of each beam and cap holes with wood plugs.
-
Step 3
Stand your 68-inch 2-by-4 up measure 9 inches and 48 inches off the floor. Mark the wood at these heights. Repeat this for all four pieces of 2-by-4.
-
Step 4
Nail the rectangle frames to the 2-by-4 frames at these heights to form the bunk beds. The nails will hold the frames and post together as you drill holes for the carriage bolts.
-
Step 5
Make sure everything is square and there are two holes where each post meets a corner of the frame. Place a carriage bolt in the hole and attach on the other side with a washer and nut. You should have 16 bolts holding up the frame.
-
Step 6
Using two pieces of 75-inch and 41-1/2 inch 2-by-4, build a rectangle and screw it together with two screws at each of the joints. Build a second rectangle out of the remaining 2-by-4.
-
Step 7
From the bottom of the posts, measure up 55-3/4 inches and 61-1/2 inches. The two 2-by-4 rectangles will fit around the posts at these heights and will act as guard rails for the top bunk. Screw them into the posts with two screws at each corner.
-
Step 8
Place your plywood in each of the 2-by-6 frames and screw it into the support beams and the frame sides.
