Building The Card Stock Downscale Centuri Hornet Part 6, Fin Gluing

The edges of the black fin can be blackened with a quick pass of a permanent marker.
Be careful and quick. The marker ink will probably be darker than the ink from your printer.

Run a thin line of white glue down the cut fin edges.
This seals the edges.

After it dries, lightly sand just the glued edge with 400 grit.
Apply another line of glue, let dry and sand again.

If done correctly, you'll seal the edges and end up with a rounder outside and trailing edge.

An engine casing was slipped into the body tube for cutting support.

Cut off any excess tube using the wrap edge as a guide.
Sand smooth any rough edge.

Glue the fins on the lines printed on the body wrap.
The black fin sits on the black line extending down from the Hornet name on the body wrap.

The top of the line is the leading edge intersection.
The lines extend a little beyond the back of the fins to help alignment.
