• Step by Step Instructions

Preparing the rails.

• Line up the rails side by side.
• Tape them together.
• Mark the axle holes one inch from the ends and
  middle of the rail.
• Make a mark along the top of both rails every two
  inches.

3
Mousetrap Placement

• The mousetrap spring should be 12 from the drive
  axle. The base plate should be glued to the
  rails at this point. Then glue the mousetrap
  to the top of the base plate with the effort arm
  facing away from the drive axle.

Base Plate

• Decide how wide you want your car.
• Cut the base plate to this width.
• Place the base plate on the rails so that the
  edge is even with the same mark on the top of
  both rails.
• Line up the side edge of the plate with the top
  edge of the rails.
• Hot Glue base plate to top of rails.

5
Modify the Mousetrap

• Holding the mousetrap with the bale pointing away
  from you. Find the top left corner of the bale.
  Cut the bale at this corner.
• Remove the parts of the trigger. Save the parts
  in a baggie

6
Wheels

• If the hole of your wheels is bigger than the
  1/8th inch axles you need an adapter. You can
  use a washer or small wheel hot glued to your
  wheel.

7
Insert the part from the bale in the top of the
effort arm.

Axles

• You are given two 1/8th inch diameter axles, 4
  long.
• Use a hammer to insert the axle into one of the
  adapters of a wheel. Repeat with the other axle.
• Insert the axle through the holes in the rails.
• Lay the car down with the wheel against the table.
