She Rises!

I installed the inner layer of "caravan ply" while the sides were still flat on the table.  I used Gorilla Grip glue and air driven staples where they wouldn't be seen.

I made a temporary right angle brace to support the sides while the roof is being installed.

At last I get to see what it will look like.  The side panels are screwed and epoxy glued to the base.

The first five roof beams are fitted into their notches and held with a screw and thick epoxy glue. 
The outside of the side panels were sheathed with fiberglass before they were put up.  Glassing a vertical surface is no fun.
