  2. Overview • Wish List • 9v LEGO train track mods • Final suggestions Ben Fleskes: Design Study: New Track Geometry

  3. New Track Geometry Wish List • Flexible track length • Improved switch geometry • More radius options • Different crossings Ben Fleskes: Design Study: New Track Geometry

  4. Criteria • Compatible with existing track • Maintain tie spacing ~ two studs between ties • 16 stud offset • Durable • Play well together – with other pieces Ben Fleskes: Design Study: New Track Geometry

  5. One Possible Answer:Track Mods 40S R 22.5 deg curve 40S R 11.25 deg curve Ben Fleskes: Design Study: New Track Geometry

  6. Or: 16S straight 4.35S straight Ben Fleskes: Design Study: New Track Geometry

  7. Why 4.35? 40S R 11.25 deg curve + 4.35S straight + 40S R 33.75 deg curve Ben Fleskes: Design Study: New Track Geometry

  8. Pretty darn close <0.1 S 15.9 S Ben Fleskes: Design Study: New Track Geometry

  9. Making it happen… What you need: • .080” x 080” polystyrene • Soldering iron • Solder • MEK (glue) • Hack saw • Exacto knife • Needle files • Flat file Ben Fleskes: Design Study: New Track Geometry

  10. Step 1: Start with a regular curve track Ben Fleskes: Design Study: New Track Geometry

  11. Step 2: Cut it apart Hint: A Dremel tool with a cut-off wheel works really well. Ben Fleskes: Design Study: New Track Geometry

  12. Step 3: Trim inside flanges Ben Fleskes: Design Study: New Track Geometry

  13. Step 4: Stage for assembly Note: the track with yellow bricks provides alignment 0.080” x 0.080” Polystyrene Ben Fleskes: Design Study: New Track Geometry

  14. Step 5: Begin Assembly Ben Fleskes: Design Study: New Track Geometry

  15. Step 6: Final assembly Hint: use a small blunt object to press the polystyrene firmly in place Ben Fleskes: Design Study: New Track Geometry

  16. Step 7: Glue Danger! MEK fumes are harmful! Follow all recommended precautions! MEK: Methyl Ethyl Ketone Ben Fleskes: Design Study: New Track Geometry

  17. Step 8: Solder Hint: solder top and sides of each rail Ben Fleskes: Design Study: New Track Geometry

  18. Step 9: File • File the excess solder away Ben Fleskes: Design Study: New Track Geometry

  19. Step 10: Done Ben Fleskes: Design Study: New Track Geometry

  20. Something a little more Complicated Ben Fleskes: Design Study: New Track Geometry

  21. Switch Mod 1: Cut the track Ben Fleskes: Design Study: New Track Geometry

  22. Switch Mod 2: Prep for assembly Hint: the remnant from a switch left can be used to modify a switch right. End of a curve track Ben Fleskes: Design Study: New Track Geometry

  23. Switch Mod 3: Reinforce and glue Hint: Use extra curve tracks to keep pieces aligned. Hint: Be careful not to glue the tracks together Ben Fleskes: Design Study: New Track Geometry

  24. Switch Mod 4: Solder and File Hint: Be careful not to dislodge metal rail when soldering Ben Fleskes: Design Study: New Track Geometry

  25. A sample layout Ben Fleskes: Design Study: New Track Geometry

  26. Another option Ben Fleskes: Design Study: New Track Geometry

  27. Or a real layout Ben Fleskes: Design Study: New Track Geometry

  28. What about curves? 104S R 11.25 deg curve 40S R 22.5 deg curve 56S R 22.5 deg curve 72S R 15 deg curve 88S R 15 deg curve 120S R 11.25 deg curve Ben Fleskes: Design Study: New Track Geometry

  29. What about a crossing? Ben Fleskes: Design Study: New Track Geometry

  30. Summary • Track mods can give you • Any length track you want • Very flexible switch track • Track mods can’t give you • Different radius tracks • No clear solution for another crossing Ben Fleskes: Design Study: New Track Geometry
