In March I worked for a few days on a chair as a design study, hoping I would find some interest in the future to build a few of them. Initially the chair components were welded together, but for shipping purposes I decided to change it to a bolted construction. Last week I was asked by a friend to build four chairs for his dining room after he visited the shop and saw the sample. He is a woodworker and will fabricate and supply the wooden seat and applied back, made from solid black walnut. I started cutting components for the first chair last Saturday, just to make sure everything fits and bolts together as planned. After a successful assembly, I cut parts of the other three chairs. Here are some images of the process! Enjoy!
After changing the components in CAD for a bolted construction, and programing it in the cutting software, I cut the parts for the first chair.
Parts after grinding to clean off any dross and ready for bending.
The process worked great in the past, so I did it again!
What a rubber mallet can do!
All the other parts after cutting and grinding!
All components after bending them on my welding table. At some point I will have a metal brake to do this more efficiently!
The next step was welding all the felt pad plates in place at the bottom of the chair legs.
Here is a picture of the inside!
The stops in my welding table ensure all parts are bolted together nice and square.
Having custom stops made with different diameters, allow spacing in 1/4″ increments between the stops.
After having assembled the front and back portions of the chair base, all that was left was fastening the sides to get the bases completed.
A friend with a slip roller was helping we to get the curved backs bent all to the same radius. Another piece of equipment that I would love to have! Will it ever end???
Here are the chair bases completely bolted together.

And the inside!
Here is the backside of the chair, ready to receive the walnut seat and applied back.
