Estes V2 Build Part 4 Fin Slots

The fin slots don't cut easily. Take your time and use a sharp knife.

You might find it easier to follow a pencil line.

Set a sharp pencil into the "trough" and draw a line all the way around the eight fin slots.

Cut following the pencil outlines.

Work on the straight sides first. Stop before you reach the rounded bottom!

Cut almost to the bottom. (shown in the picture)

Flip over the tail cone and finish from the other end.

Your knife will slip off the round end if you get too close to the end.

It took four passes to cut through the plastic.

I found it easier to "rock" the knife blade around the rounded ends.

Set the blade on the pencil line before using any pressure.

This is the other side of the "rocking" motion

Again, it'll take a few passes to cut through the plastic.
