Estes Nike Smoke #7247 Build, Part 3, The Enerjet Smoking Nose Cone

I used my aluminum angle to get side slot sides straight.

The short end cuts were made by punching the tops and bottoms with a sharp blade tip. Punch the top corner with the sharp side down. Turn over the blade and punch cut the bottom with the sharp side up.

The shock cord attachment lug will be in the way of the internal BT-5 tube.
A hobby saw cut it close to the surface. The remaining nubs were sanded off. A small sliver was opened up after sanding smooth.

The hole was continually widened until I could get a dowel in. 220 grit was wrapped around the dowel and the hole widened.
Sand a little and check the tube fit.

The tube was slid in from the bottom and can be seen inside the cone end.

Shave off little by little until the tube slides through.






Here's the BT-5 fit at the bottom and top.

On the left I've pencil marked two holes that will be drilled out for the shock cord tie.
