How I Fixed a Lyon Chair Part 2

I continued to trim the piece of sheet metal. I used a Beverly shear to cut along the lines I sketched on the metal.

I used two different files to sand the edges of the metal leg. The first file was more coarse than the second. I used sandpaper to refine the edges.

I used the break, shear, and roll machine to bend the metal. The angle of the bend was approximately 90 degrees.

I used a body hammer to flatten the upper end of the stool leg. I attempted to straighten out the end of the leg so that it could be attached to the chair.

I used an old stool leg as a template. I continued replicating the shape of the old leg by hammering the sheet metal on different surfaces.

I hammered the lower end of the stool leg. I hammered the metal on different surfaces to duplicate the original design.

Before attaching the leg, I used sandpaper to remove the rust surrounding the corner of the stool. I used coarse sand paper to remove and flatten large metal bumps.

I used files and sandpaper to flatten and sand down the corner of the footrest. Sanding down the corner made welding the replacement leg easier.

I used clamps to hold the leg in place. I double checked my initial measurements and made sure each leg was the same length.

My teacher welded the new leg to the stool. He added welds along the footrest and the upper stool corner.

I sanded the bottom of the stool and removed a large layer of rust.

Although the new stool leg was now attached, the thinner material meant that it was still weak.

I used cardboard models to test out different ideas. I brainstormed different methods of making the stool leg stronger.

I selected this stool and brainstormed some ideas as to how it could be repaired. The first step to fixing the stool was identifying the problem. The broken leg was made up of thinner material than that of the other legs.

In order to make the replacement leg stronger and the stool more stable as a whole, I decided to attach some extra sheet metal between the legs. The crossbeam support would work to fortify the structure.

I sanded some of the rust off of the stool and then placed the stool tightly in the vice.

The next step for the stool repair was to remove the broken leg. Afterward, I used a drill to pierce through some of the major spot-welds between the leg and the stool.

To get used to the air hammer, I cut up a couple of practice pieces.

I used the air hammer to detach a majority of the broken leg from the rest of the stool. The air hammer allowed me to break through many of the minor spot-welds that kept the leg attached.

I clamped down the stool and turned on the air hammer. I used the air hammer to remove the residual material from the worn-down stool leg.

 I cut and trimmed an old piece of sheet metal using a Beverley shear until it was two inches wide.

I then used the brake, shear, and roll machine to bend the piece of metal in half.

I hammered the piece of metal on an anvil to try to replicate the shape of the lower end of the stool legs. The scrap metal served as a practice piece.

I was now ready to move onto creating the replacement leg. I made a cardboard replica of the stool's legs to guide me as I cut through the large sheet of metal.

 I used air shears to cut roughly around the cardboard model.

With the Beverly shear I trimmed the piece of metal until it roughly resembled the other stool legs' dimensions.
