Estes Cosmic Interceptor Build, Part 11, Cutting The Intake Tube

Draw a centerline down the "K" tube.

The template is cut from the instructions and taped to the tube.

Line up the centerlines. Trace with pencil.

TIP: If you set the wide, rounded end of the template very close to the tube end - there is just enough to make a second intake fairing if you screw up the first attempt. 

The sidelines are straight and you can use a straightedge to cut them. Tape a metal ruler down the side pencil lines.

Or you can cut the lines freehand.

Don't cut through on a single pass! Use a new blade, cut slow and controlled. 

The edges are cleaned up with sandpaper on a block.

On the top is the rough cut,

Below is after sanding the edges flat an rounding the front and rear curves.
