The article, with parts list and step-by step directions is here: Popular Woodworking article: Norm Abrams Adirondack Chair
I used rough pine for the chair, which meant I needed to pick out pieces without loose knots, and with areas that looked clear as possible for the parts I had to make, and then joint and plane them to size. The thickness of all the parts is 3/4", the legs, front crosspiece and seat slats are rectangular, with no need to make fancy cuts on. The tops of the back slats, the arms, arm brackets, side members and rear crosspieces need to be cut to shape. I used my jigsaw but a bandsaw would be easier (I don't have one yet).
Jigsaw cutting the side member:
All the pieces laid out:

The chair is put together with screws as well as some carriage bolts. For the screws I plug them afterward, so each place a screw goes needs a hole for the screw as well as a larger hole for the plug.
**This "how-to" will be a blog post in the near future**
These next two photos show the arm with it's three large holes and the front crosspiece, lower rear crosspiece and leg with two large holes (on each side), waiting for the plugs to go in:
Now you can see the upper rear crosspiece is bolted on and the holes are all plugged in the arms, legs and front crosspiece:
While the chair was at this stage I painted it with 3 coats of exterior house paint. After making similar child size chairs ( here ) I realized it would be much easier to paint the slats before they were attached to the chair. It's hard to get the paint in between the slats, so the chair base was painted and just the backs and sides of the back slats and seat slats. I couldn't paint the fronts yet because the screws still had to be attached and plugged.
All the base painted and back slats (with just their backs and sides painted) attached:

Since my husband is a Montreal Canadiens fan, I decided to put the team logo on the chair. I found it online and printed it on my printer to the size I needed. Then I cut it out and traced around the parts to transfer it to the chair. I used acrylic craft paints for the white and blue, and some painters tape to keep the lines straight.
Here it is:
This is a very comfortable chair and he was happy to get it as his present!
