Assemble Hands and Arms
Refer to the cut list for creating the thumbs, forefingers, middle fingers, pinkies, palms and forearms pieces. Create one set, then another as a mirror image of the first.
Cut the angles on the parts using a miter saw. Drill pocket holes in the parts (image 1). Drill pocket holes in the ends of the upper arm. Assemble the hands using glue and pocket-hole screws (image 2). Attach the upper arm to the forearms (image 3). Sand any rough edges and corners, and apply black paint to the arm/hand assembly.
Lay the body facedown. Position the arm/hand assembly roughly centered on the middle circle of the body. Attach the arm assembly to the body using three 1-1/4-inch deck screws and no glue (image 4). Using screws without glue will allow you to remove the arm/hand assembly for storage.
