Step 1: Log Sides
Next I cut a large 4" swim noodle in half using a table saw. After doing some basic shaping of the swim noodle with a large bread knife my daughter coated both the noodle and plywood with contact cement. I then bonded the two pieces together which provided the contour of the log sides.
After the glue was completely dry I did a little more shaping and trimming with the bread knife. I then coated the entire noodle side with Bondo-Glass (available at any auto parts store, large hardware store, or Wal-Mart) putting it on in one direction but a little sloppy so it would look like tree bark when I finished. Bondo-Glass hardens in about 15 minutes, which keeps the project moving quickly.
After both sides were cured I sanded them to remove any sharp edges. We gave the sides a thorough base coat of gloss black and then brown. This gave the sides a realistic log look.
