Estes Nike Smoke #7247 Build, Part 4, The Enerjet Smoking Nose Cone

Two holes are drilled into the nose cone base for a shock cord loop tie.

Start the hole by spinning the tip of a #11 blade in the plastic. Use an older blade, this really dulls a new one.
The hole is widened by spinning a small diamond file in the holes.
One of the raised plates is cut for a smoke release hole.

Trace around the raised plate with a pencil so you can better see it.
This plastic is harder and a bit more brittle than the old blow molded nose cones. It takes quite a few passes with the knife to cut through it. Leave the top 1/3 of the hatch still attached to make a "hinge".

The port is bent open and upwards making a pressure "hinge" in the plastic. Be careful, this plastic is not as flexible as what Centuri used on their Nike nose cones. It can crack at the hinge.
It has to be opened wide enough to allow the talcum powder to easily blow out.
