1930s Amilcar

Chassis start. The outline of the chassis was scaled up from photographs and drawn onto a large sheet of fibreboard with the locations of major components also drawn on to check that the build will be more or less compliant with the guidelines for Cyclekarts. The chassis rails are 75x25mm steel box section which where shaped by slicing segments out of the box section to allow the rails to bend and follow the outline drawn onto the fibreboard. The rails were then secured to the board and the segments TIG welded back up to fix the final shape. This approach was selected due to the lack of facilities to roll form the rails.
