Estes Colonial Viper #1310, Part 5, Clay Weight & NC Shoulder Fit

The cut plug was slid into the nose cone shoulder base.

To seal the end before pressing in the oily clay, the card stock disk got a coat of wood glue applied with a Q-tip. Let dry before adding the clay.

The old Estes lead weights weighed .12 oz. each. This model had four of them tied inside the nose cone shoulder.

I weighed out the equivalent amount of clay.

The clay was pressed into the nose cone shoulder, filling it all the way to the top.

On the right, the nose cone was slid into the BT-50 H tube.

These nose cone molds were originally made for Starlight Rockets and are now owned by Apogee. They fit the heavy walled tubes very well, but there is a light overlap at the shoulder base.

This was sanded down with 220 grit on a block, followed by smooth sanding with 400 grit.
