Estes Cosmic Interceptor Build, Part 3, Prepping The Engine Vanes

Lightly sand the laser cut ash edges with 400 grit.

The pics show the before and after sanding.

The exposed edges (shown here marked with pencil) should be sealed. If not sealed, the paint will soak into the open fibers and the edges will be uneven.

A segment of tubing will glue over the edge without the pencil line. 

Run a narrow bead of glue down the side edges. 

With the side of your finger, even out the bead getting a rounded even coverage from side to side. 

After the glue bead dries, lightly smooth with 400 grit.
