The finished chair. Made from Redwood and finished with Rubio Durogrit in Steppe Look.

The plans for this "Kitchissippi" chair are from Lee Valley. The plans provide a paper template which I cut out, pasted to some plywood, then I cut and sanded to the final profile. From there I simply traced the forms onto my lumber, cut close with a bandsaw, and then used a router table to reach the final shape with some sanding to smooth out some areas. 

A comparison of the Kitchissippi chair to an Adriondack chair. The main difference is a higher seat, and slightly straighter back. (Image from the cover sheet by Lee Valley / Veritas Tools.)

The templates created by cutting the paper sheets provided and pasting them to some plywood. 

Some of the parts after cutting and shaping the lumber stock. This pile consists of the legs, arms, and back slats for two chairs.

The seat slats.

The rear legs and back support. 

Installing the seat slats. I used 3/8" dowels as spaces between the slats to keep consistent spacing.

Front legs and arm supports attached.

Completely assembled, just need to stain/seal the wood.
