To begin building the Adirondack chair-style Loveseat Glider Rocker, we'll start by cutting the feet for the base of the glider rocker out of 2x4 on the band saw. You can cut these feet in any shape that you like as long as it is something similar to the shape on page 3 of the Free Plans you downloaded in step 1.
Next, using your circular saw or compound miter saw, cut two 2x4 sections at 16" and round over the four corners with a 1" radius on your band saw. These two pieces will form the tops of the base sides (as shown on Page 3 of the plans).
Then, cut four 2x4 pieces at 15-1/2" to serve as the vertical pieces on each end of the base. While you're cutting, cut two pieces of 2x4 at 42" in length for the top and bottom spreaders.
With each of these ten pieces cut, set up your table saw with a stacked dado blade set to cut half-lap joints in the foot, top and two vertical pieces of each side of the base, as shown on page 3 of the free plans.
These half-lap joints should be cut exactly the width of the joining board and at half of the depth. The fit should be snug, but not too tight. (Note: These joints could also be done using mortise and tenon joinery should you so choose.)
With the half-lap joints cut in all four pieces of each side of the base, dry fit the four boards together to check the fit. If it looks good, assemble using some woodworking glue and 1-1/4" deck screws in pre-drilled, countersunk holes. Repeat with the opposite end of the base.
Now would be a good time to sand each of the two base side assemblies. Pay special attention to the curved cuts from the band saw.
After both base sides are completed, install the two spreaders between the two bases, as shown on page 2 of the free plans. These two spreaders should be centered on the top and bottom of the base sides, as shown. Attach using 2-1/2" deck screws.
