With a load of 200lb evenly distributed across the seat of the chair, there is less that 8 lb.* in. of torque at each joint.. Since this is only my first design, I decided to build a 1:8 scale model of the chair out of wooden matches and superglue. Here are the following steps to building it.
Step 1: Set up and prep
Step 2: Profile layout
Step 3: Building the seat
Step 4: Attaching the legs to the seat
Hopefully this model will hold up as I move up to larger scale models! Have fun!
