The third and final top is finished, I am steadily improving... I hope this will be the last one though.
The challenge is always to get the plastic as tight as possible so I used more bungee cords to pull the edges. As on the two others I started with gluing and sewing the bottom edge.
Pulling the top edge tight. This roof had a flap of material that connected to metal bow to the roof material so I could not pass the bungee under the bow. I used a big needle to pull some nylon cord through the flap and connect the bungee to the window.
Next, I used clamps to grab the edge of the roof and pull it down, the combination of pulling the window up and the edge of the roof down helped to tighten the installation.
At this point I sewed the top edge.
The ends are a challenge. Three bungee cords pulling the corners and the center and a clamp on the edge of the top to pull it in the opposite direction.
The ends were sewed and then the glue applied all the way around to seal the roof.
The roof is back on the car, I will add a photo... soon.
