Create a basic box, insetting the short sides as shown above. You can either use pocket holes or pre-drill through the long sides and use 1 1/4″ screws.
STEP 2
Screw in two planks on each side, countersinking your screws through the top. Space the boards 1/2″ apart
STEP 3
Create what will become the seat. Screw the 1 x 4 boards (1/2″ apart) onto the 2 x 4 arm rests (d). Make sure that the 2 x 4s are at least 1″ inset from the edge to allow for them to fold into the box nicely. (you’ll be making two of these)
STEP 4
I have NO idea how to add hinges in sketch-up, but attach the seat that you made in step 3 to the plank you screwed in in step 2. I found it easier to attach the hinge to the seat (on the side opposite the arm rests) and THEN attach it to the screwed-in plank. Make sure to space them 1/2″ apart.
STEP 5
STEP 6
Attach your second set of hinges to the seat back, on the opposite side of the 2 x 4s, and then attach to the seat (easy to do with the seat “up”). Make sure to space the 1/2″ apart.
- 2 – 1 x 8 @ 8 Feet Long
- 6 – 1 x 4 @ 8 Feet Long
- 1 – 2 x 4 @ 8 or Stud Length
You will also need:
- 4 sets of exterior grade hinges
- Rope OR 4 exterior grade handles (search “gate pull” or “gate handle”)
(a) 2 – 1 x 8 @ 47 1/2″ – long sides of box
(b) 2 – 1 x 8 @ 46″ – short sides of box
(c) 12 – 1 x 4 @ 47 1/2″ – top planks
(d) 4 – 2 x 4 @ 7 1/2″ – arm rests
(e) 4 – 2 x 4 @ 12 1/2″ – back support/handle
