This project uses a mix of wood and PVC pipe. Because this project won't remain outdoors for long, it's not necessary to use exterior-rated wood. We've used a mixture of spray paint and brush-on paint for the wood body parts and wrapped the pipe in electrical tape. There are many different colors of electrical tape available, so feel free to make up your own color scheme for this creature.
Body Segments – four 15-inch edge-glued round panel
Base – one at 3/4" x 3-1/2" x 24"
Head – one at 3/4" x 3-1/2" x 8"
Spacers – six at 3/4" x 3-1/2" x 2"
PVC Legs – twenty at 1-1/2"* x 24"
Eight 90-degree PVC elbows
Sixteen 45-degree PVC elbows
*interior pipe circumference
This project uses pocket hole joinery.
Cut 20 legs from PVC pipes per the project parts list using either a miter saw or a hack saw. Wrap the 90-degree elbows and 45-degree elbows with red electrical tape (image 1).
Insert one end of each leg in a 45-degree elbow and mark the position of the part on the leg. Repeat on the other end of four legs. Insert the other end of the remaining 16 legs in a 90-degree elbow and mark the position of the part. These marks designate where to start and finish wrapping the legs with electrical tape.
Wrap each leg with black electrical tape, beginning and ending at the marks (image 2). Use the configuration (image 3) as a guide for creating eight leg assemblies. The last four legs will be used in the final assembly.
Apply spray paint to both sides and edges of three of the body segments (image 1, below). Apply spray paint to one side, the edge, and a 3-inch wide strip on the other side of the fourth body segment.
Cut the base to length and apply spray paint to all but one face of the part. Position two body segments with the edges touching. Use a straight edge to position the parts flush with each other.
Apply construction adhesive to the unpainted face of the base (image 2) and attach using #18 x 1-inch wire brads.
Cut the head to size and shape, apply spray paint to the head, drill pocket holes in the head for 3/4-inch stock and paint the eyes on the head using white paint (image 3).
Place a couple strips of painter's tape on the body segment with the 3" wide strip and apply red paint to the unpainted area. Apply red paint to about half of the edge of the remaining body segment.
Cut the spacers to width and apply spray paint to the faces and ends. Apply construction adhesive to the bottom edge of the spacers and position them. Use one of the legs as a guide for positioning the spacers to allow for enough room for the legs in the final assembly. Allow the adhesive to cure.
Position the head on the body segment with the red edge and attach using 1-1/4" pocket-hole screws (image 1).
Cut the spacers to width and apply spray paint to the faces and ends. Apply construction adhesive to the bottom edge of the spacers and position them. Use one of the legs as a guide for positioning the spacers to allow for enough room for the legs in the final assembly (image 2). Allow the adhesive to cure.
Apply construction adhesive to the top edges of the spacers and position the remaining body segments (a square will help in positioning the edges flush) and attach using #18 x 1 1/4-inch brads (image 3).
To test fit the project, place all of the parts and assemblies on a large work surface. If using a garage floor or driveway, place a drop cloth down.
One at a time, insert a leg through the body assembly and in between the spacers (image 1).
Attach one leg assembly at a time to the legs in the body assembly (images 2 and 3). Make any adjustments as needed in test fitting.
Note: Depending on the terrain, you may need to reposition the 45-degree elbows on the end of the legs that touch the ground so the legs will stay in place. Also feel free to rotate the legs as desired to enhance the look of the spider and give it the look as if it is in motion.
