This first picture shows the legs dis assembled and the leg in the bottom of the photo with all of its broken parts.
This next photo shows the leg being glued up with the original parts.
After the leg had dried, I cut away material on both sides of the leg to receive a patch. Note how the break (and previous repairs) can be seen in the center of where the wood has been removed. The patch is inserted into the space with glue.
The patches being glued in place.
After the glue dries, the patch is cut to a rough shape on the band saw.
Gluing the patches on the other arm.
Here are two pictures of the chair with the arms and the broken leg (facing out) repaired and touched up to match the existing finish.
