Carving the chair's crest rail was fun, and I think that adding the scroll detail improved it. The next step was to glue the parts together. In some cases, where parts were not disconnected but just loose, I injected glue in between the tenons and the mortises; I used liquid hide glue throughout the proses. To inject glue in between tenons and mortises I drilled a hole and inserted a syringe to force the glue in.
After the glue dried I sanded the chair and applied two layers of polyurethane clear finish.
