What you need:

  • .080” x 080” polystyrene
  • Soldering iron
  • Solder
  • MEK (glue)
  • Hack saw
  • Exacto knife
  • Needle files
  • Flat file

step 2 cut it apart
Step 2: Cut it apart

Hint: A Dremel tool with a cut-off wheel works really well.

step 6 final assembly
Step 6: Final assembly

Hint: use a small blunt object to press the polystyrene firmly in place

Ben Fleskes: Design Study: New Track Geometry

step 7 glue
Step 7: Glue

Danger! MEK fumes are harmful! Follow all recommended precautions!

MEK: Methyl Ethyl Ketone

step 8 solder
Step 8: Solder

Hint: solder top and sides of each rail

Ben Fleskes: Design Study: New Track Geometry

step 9 file
Step 9: File
  • File the excess solder away

switch mod 3 reinforce and glue
Switch Mod 3: Reinforce and glue

Hint: Use extra curve tracks to keep pieces aligned.

Hint: Be careful not to glue the tracks together

summary
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
