Here is the new rocker fully assembled and ready to fume. I am sure that you'll recognize many of my influences in it.
Here it is after a couple of days in the fuming chamber (shown below) with some janitorial strength ammonia. I should say that anyone attempting this should be careful to avoid the fumes. I did this by hoisting the cover up to the roof of my barn with a pulley while standing away from the area. This way the fumes could dissipate safely.
I removed the chair from the chamber and oiled it, only to realize that I wanted it darker, so I put it back in the chamber and the color continued to shift despite the oil. I am very pleased at the way that the oak and the butternut changed colors so similarly. It looks like the whole chair is made from one type of wood.
This shot shows the thin spindles. They have just enough give.
One of the most lovely qualities of the fuming is the way in which it accentuates the rays. I oriented the crest and spindles to show this. I like the way that it looks like a scribbled drawing that catches the light. I guess that there is still a painter in me somewhere.
Here is the chamber that I built. It is a simple box made from 1"X 2" and 2"X 2" lumber covered with plastic. I cut a hole in the plastic about 3 inches square and covered it with clear packing tape to create a window so that I could judge the progress.
I am looking forward to playing so more with this method of coloring the wood. The clarity of the grain (especially in the seat), and the deep colors add a lot.
