Semroc Defender Build Part 14 Nose Weight

I looked up the Centuri Defender instructions at:
http://www.oldrocketplans.com/

Here's step 11 from the instructions.
With three C6-5 engines, the recommended nose weight is .27 oz.





Here's the clay weight from the Semroc kit.
The clay square weighs in at .55 oz.





In order to fit the clay into the ST-5 tube at the top, you have to roll it into a round cylinder.

Take into account the shoulder length from the lower adapter and the nose cone shoulder. All of the supplied clay won't fit into the small ST-5 top section. I cut off the excess.
The cut clay weighed .40 oz. That's more than the Centuri instructions call for, but with three engines under it, the extra weight shouldn't matter.
