Applying Ablative Coating

  • Apply ablative (using layup jig)
    • Set up layup jig (looks like a spit with a pole running across it that can be rotated by hand)
    • Put old nose cone or some coupler inside the nose cone and put both over the pole. The coupler or whatever you can find to fit inside the nose cone gives you something to grab onto so you can turn it after you apply the ablative.
    • Mix 100g Systems 3000 resin + 18g Systems 3000 hardener + 17g phenolic microballoons
  • Use heat gun to dry (don't overwork)
