Introduction: How to Build a Chair for Your Christmas Dog

I wanted to design a chair with the lowest possible moments at each joint but stay away from the original straight leg design. By using Force Effect by Autodesk on an Ipad, this is what I came up with:

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

First is the set up for the project. You will want to place wax paper over a hard surface that you don't mind getting cut up by razor blades. (I used an old notebook that I had laying around) Set out your wooden matches and cut 8 of them to 2in. and 2 more of them to 1.75in. using the razor blade and set them aside. 

Step 2: Profile Layout

Layout the profile of the legs with 4 of the 2in. legs forming an "M" and the 1.75in. match forming the top. Make 2 sets of these and use a ruler or straight edge to align the bottom of each of the legs. Then, place a small drop of super glue or wood glue at each of the joints. Let these dry and try not to bump them. 

Step 3: Building the Seat

To build the seat, lay out 16 matches side to side with the heads alternating. Place a line of glue perpendicular to the matches on the seat and place a supporting match on the glue path you just drew. This will provide support and keep the seat together. 

Step 4: Attaching the Legs to the Seat

This is the tricky part. You need to have something hold the legs in place while the glue drys out. I used a bent piece of cardboard with a slit cut in it. Once both legs are dried, the chair is complete and feel free to place your Christmas dog on top of it :) 

Hopefully this model will hold up as I move up to larger scale models! Have fun!

    should have lit the matches for the photo, the amount of time it takes for a cataclysmic change reaction and phase change of phosphoro in comparison to a camera flash is relatively reasonable. Also, the wax paper serves as a safety net in case one of the matches falls due to the force of your photography. All around though, well done. Balance the force::applies for kinetics and statics, and therm o-dynamics, and dancing, and typing.

    Leaving the heads on the matches makes it seem like you want to torch your Dog whether by accident or intent. Is that the deal here?
