The design of the bodywork is progressing and updates have been made to the chassis to get the EPAS column to fit and have suitable locations for mounting.

The body design needs finishing before I can start on its internal ribs and stiffeners that will give it rigidity and provide the attachment points for the panel pieces.

The plan for building the body shell is to use the construction method employed for light aircraft; namely internal lightweight frames with a riveted skin. By using countersunk rivets it should be possible to attain a high finish by using a combination of body filler, sanding and a high build primer.

The body ribs would be held by a framework and the same connection locations would be used to attach the body to the chassis; hence the hoop frames of the chassis.

Below is a picture of a full strength countersunk rivet connection, where the plates have been dimpled prior to the rivet being affixed. A combination of rivets and a flexible epoxy glue will give a lightweight rigid shell.

Some good sources for dimple flush riveting come from the home aircraft builders in the USA the photo above is linked from the sonex1362 blog. Other links are; vansaircraft for military riveting design specs and skysaber.com for flush riveting solid rivets.
