I used the Kreg Pocket Hole Jig
for all my joints
Assemble the glue up the seat
Measure and cut all members except for back member (will measure this on in place later)
Since this is a symmetrical chair I clamped and cut 2 members at one time (this ensure very consistent and accurate cuts)
Join all members except for back, clamp back in position and mark cut.
Stain another day :)
