The Alleweder construction is based on this ground plate. Primary components (main spar, rear fork, wheel panels) attach to this plate.

These panels attach to the nose of the ground plate and become the bottom sides of the nose of the vehicle.

Using clecoes to attach components allow for assembly temporarily. This facilitates de-burring of holes and bonding of panels prior to final riveting.

With the nose panels riveted, the front wheel panels are ready to be attached. The small box at the front of the wheel panel is a suspension point.

The main spar, wheel panels and fender panels clecoed on place. Foreward is to the left in this photo.

The same components with the top arch temporarily in place, more clecoes around the fender and wheel panels.

The same assembly as in the previous photo, fully riveted. The structure is a bit flexible at this stage and easily bent as desired (or not).

The spar which holds the bottom bracket, the nose bulkhead, and aft bulkhead are in place, and the nose panels are clecoed to the nose bulkhead.

A lot of clecoes to hold the curve of the panel to the nose and fender wells means a lot of rivets to be placed.

A bit cleaner appearance once the rivets are installed. The nose structure is very rigid at this point, but the top skin has yet to be installed or clecoed.

Another view of the assembly with the lower nose panels riveted. The tail bulkhead with the rear wheel fender is visible in this photo

The ground plate alone is very weak, but is strengthened with stiffeners placed between the seat plate and ground plate. This template makes locating the stiffeners easier.
