  4. GuttaPercha Rubber Balls Wood 2012 1900 1940 1600 1800 1840 Feathery Cube Modern Balls 3

  5. Wood Ball • Hard wood coming from beech trees or boxroot trees • Unreliable as they were never perfectly round • High drag creating surface • Unpredictable trajectory • Travelled 100 yards on average 4

  6. Feathery Cube • Leather and feather construction • Very expensive, time consuming to make • Excellent flight characteristics, due to rough leather surface, drag resistance • Approximately same size and weight as modern day ball • Leather/feather construction allowed compression on impact for more control • Travel distances up to ~175 yards on average 5

  7. GuttaBall • Made of GuttaPercha, a gum tapped from a tree indigenous to Malaysia • Malleable when boiled in water, becomes harder on cooling • Cheaper than Feathery Cube and therefore more popular • Prone to mid-air fragmentation • First ball with dimpled surface for improved flight path • Bramble design was first mass produced ball with dimples • Same properties as Feathery Cube 6

  8. Rubber Ball • Invented in 1898, mass produced 1901 • High tension rubber thread wrapped around solid rubber core • GuttaPercha cover (first multi-layer composite ball) • Became most widely used ball due to improved ball control and distance 7

  9. Modern Balls • Combines multilayer technology • 3/4 vs 2 • Expensive (Tour Balls) vs Range balls • Composite layer properties combine • Workability (Tour Balls) with Distance • Distance and Forgiveness • Specific properties tailoring 8

  10. Titleist Pro-V1 and Pro-V1x • Combines multilayer (3) technology • Polybutadiene SINGLE core • Moderate Compression (v1) • Ionomer casing • Higher compression thin layer (v1) • Urethane cover • Durable, moderate compression 9

  11. Titleist Pro-V1 and Pro-V1x • Combines multilayer (4) technology • Polybutadiene DUAL core • Soft, High Compression centre (v1x) • Low-Moderate Compression outer • Ionomer casing • Higher compression thin layer (v1x) • Urethane cover • Durable • Moderate compression (v1x) 10

  12. Future Ideas and Monetizing • More diverse composites and layers • Better manufacturing techniques **Build a ball for your gameplay and style** 11
