Following the tutorial i was not satisfied with the shape, hence i choose an alternative approach to obtain a more realistic result:

  • rails are the sides and ruled surface is from back to tip (the tutorial does it the other way around)

  • sweep:

    • for a better shape i chose the sides as rails instead of back + front

    • Blendng: Rail2 instead of Blend

  • approximation curve: 

    • increased Approx Tolerance to 1mm

    • Degree Max: 5
