Centuri Flutter-By Build, Part 4, Paper Laminating Fins

Instead of the strakes the fins will be reinforced with paper lamination.
Mentioned earlier, this is the way the original kit  fins were strengthened.

Only the leading edges of the fins were rounded.
Trace around the fins, then add a second line about 1/2" outside the fin border. This second line insures coverage and keeps the glue on the paper and off your work area.

Cut the four tracings with scissors just outside the wider 1/2" pencil border.

Apply a smooth glue stick coat. Just glue one side for now.
Be sure the edges are well coated.
Go beyond the center line. Once the fin is set down you won't be able to get glue close to the leading edge.

Set the fin down with the rounded leading edge slightly away from the center line to allow a roll over of the paper.
I've switched over to a clean hard surface, the back side of a hard cover book. The corrugated cardboard I was working on won't allow smooth burnishing.

Turn over the fin and burnish with a smooth tool. work from the center out making sure the leading edge is smooth with no wrinkles or raised areas.

While the glue stick gives you some working time before setting up, you should work quickly.
Go to the next post and continue with the other side.
