Make your helmet more aerodynamic while revealing your inner artist! This instructable will introduce you to composite manufacturing and get you closer to being Lance Armstrong.
Step 1: Sketch the shape. Dream big!
Drawing inspiration from both the fish and a nearby airfoil, I put a piece of butcher paper underneath the helmet so I could sketch a few ideas and see how they looked. Here's a parts list for this project:
-Fiberglass cloth, epoxy resin, slow cure catalyst (can buy at Home Depot; ask for fiberglass boat supplies)
-Foam sheets you can cut with a hotwire (plus a hotwire cutter; or make your own)
-String, masking tape, hot glue, 5 minute epoxy, string, masonite scraps (see step 2)
-spackle (same kind used for drywall is fine) and spackling/putty knife
-metal bonding compound (should be sandable)
-Sandpaper (80-100 grit), razor blade/scissors for cutting fiberglass cloth
-latex gloves, safety glasses, respirator with organic vapor/HEPA filters
-a BIKE HELMET you're ready to convert into a MASTERPIECE!!!
