WARNING : This Rollaway experiment is performed with the railroad entry just level with the entry of the ramp. Unfortunately the end of the railroad track has to be 2 mm BELOW the entry level of the ramp, so that the N-gauge exit track is sloping downhill........

• SMOT V 1.03 :
  • Each magnetic ramp : 12 magnets in 3 layers of 4 magnets (length=160 mm),
    • Ceramic Magnets( ferrite ) : 25 x 40 x 10 mm
    • A wide steel backing : 25 x 160 x 4 mm
• 25 mm steel ball ( weight 70 gr )
• 20 x 20 mm aluminum U channel
• Plywood and cardboard for the base

Magnetic ramps spec :

• Input gauge : 90 mm
• Output gauge : 60 mm
• Height of slope : 25 mm
• Length : 130 mm (slope) + 30 mm ( entrance ) : total length : 160 mm
