Step 13: The Tail Box
Once the trike is inside the shell and the seat & boom supports are installed, the tail box bezel may be glued in place. As before, clamp everything in place with binder clips and make absolutely sure that everything is square. That is, where the tail box lid will eventually be hinged, ensure all the vertices are perfectly aligned. You may even want to temporarily clamp on some of the other hood sections just be absolutely sure.
Once the bezel is glued in place and the remainder of the supports are installed, the tail box lid may be installed. It is glued along a single tab directly behind the rider's head. Clamp it in place and make sure it lines up well with the bezel.
The tail box lid is held down with magnets. You may choose to hide the magnets between the layers of coroplast (see the section, "Cutting out the door") or you can simply glue them directly to the face of the coroplast. After all, the magnets won't be seen when the lid is closed.
I used five pairs of magnets as in the photo. Glue them to the tail box bezel first. Don't forget to spray the coroplast with PolyPrep first! When the glue has dried, stick on the mating magnet and apply glue to the top. Close the tail box lid so the magnets come in contact with the tab, and tape in place until the glue has dried.
With five pairs of magnets, the tail box stays neatly in place and does not move around when the velomobile is in motion.
If you like, you may also choose to permanently attach the tail box lid, or leave it off completely and make the tail box bezel a solid piece.
