Rocketarium Hydra Sandhawk Build Part 5, Nose Cone Prep

The supplied nose cone clay weighed in at almost one ounce.

A hole is drilled into the back of the nose cone base to install the clay weight. It should be large enough to push in the clay.

TIP: The instructions say to use small balls of clay instead of rolling clay worms. This is a great idea. 
Make small pea-sized balls of clay and drop them in the hole. The small balls of clay will fall more evenly towards the interior tip. Think of crushed ice falling into a cup, more gaps are filled. Pressing the small balls of clay with a dowel is easier than chasing around clay worms inside the nose cone.

The raised seams were sanded down.
My medium CA fill wouldn't stay in the concave seams.
The nose cone was made of HDPE plastic.
You are told to sand the plastic so the primer and paint will stick better.

I may have to use some automotive spot putty for these seams.
