Carded Downscale Black Brant VB - Part 5 Laminated Fins A

I've written about the cereal box laminated fins before.
If you haven't made fins from a card stock laminate you might be surprised how strong they are.

These fins are actually a triple thickness of:
1. Printed 100 lb. card stock (one side)
2. Cereal Box cardboard
3. Printed 100 lb. card stock (the other side)

The outside printed layers of 110 lb. card stock are "butterflied" and fold over the cereal box cardboard at the leading edge.
If folded and glued correctly, this makes a rounded leading edge on the finished fin.
Trust me, it's easier to do than read through the description.

You'll need :
The fins printed on 110 lb. card stock, 220 grit sandpaper, cereal box cardboard (this is from a Cheerios box), glue stick, straightedge and a sharp hobby knife.

First, rough up the printed side of the cereal box cardboard with 220 grit sandpaper.
It won't take much, just remove some of the gloss and ink.
The glued outside layers will stick better if some of the ink is removed.

This sanded ink and fine dust can get everywhere! Dust off the cardboard and wash your hands before gluing anything.

You will need a straight long cut to be the inside leading edge of the ply fins.
With  sharp knife and straightedge, cut off the crooked edge down a long side of the cereal box board.

For a rounded leading edge, lightly sand the the square cut you just made with 400 grit.
Don't over sand it, just knock the corners off the edge.
