Except for finishing and the arms, the chair is done. It's glued-up and every joint is pegged:
I am not going to tell you it is perfect. All of the joints on the outside are tight but on the inside there are a few gaps in the .00X" range. The chair rocked about 1/8", likely a result of my trimming the compound angle joints on the seat rails, which I solved by trimming the legs on the longer diagonal about 1/16" each. There is the grain mismatch on the right rear leg/arm. I give myself an A-. My standards keep going up as my skills improve, so I can never achieve them. That's good and bad. For the most part, I don't think about this after the piece is complete and it keeps me striving to get better.
I went back to the lumberyard and they still didn't have any 5/4 or 6/4 QSWO; the whiskey distillers continue to buy it all. I had to buy an 8/4 piece:
$54!! I also bought Pendleton wool upholstery fabric for the seat. It is usually $84 per yard but they are having a 30% off sale on remnants:
It's more than I need but I can use it for other things and I really like the pattern. All told, materials for this chair will cost almost $300! Yikes. Maybe that's the reason the chair isn't reproduced commercially, that and the fact that it takes so much hand work to build it.
I have reluctantly given up on the idea of making an exact copy of the original from photographs and an inaccurate construction drawing, so I contented myself with making a template for the arms that looks right and seems to match the photos:
Ray Neufer made several copies of the chair later in his life, this one for example. It clearly doesn't exactly match the original, especially the shape of the back, but I don't think he cared. You'll notice he has a grain mismatch too. I feel better.
