Estes Constellation Build Part 10, Nose Cone and Adapter Details

On the left is the nose cone and adapter from the Semroc kit.
You'll see these shoulders through the clear payload section when the model is finished. I usually sand these flat then round the edges.

On the right is the dry fitted payload section with the rough ends smoothed out.

TIP: To get a sharper edge on a balsa nose cone shoulder -

Brush on some CWF just slightly over the edge.
I'm not covering the entire nose cone yet, just the shoulder edge. this leaves the nose cone dry to hold on to it.

Slide the nose cone shoulder into a squared BT-50 tube.
Turn the nose cone and CWF on the shoulder onto the tube top edge.

Turning the nose cone base forces the CWF into the shoulder lip.
In the picture you can see the raised ridge of CWF at the bottom.
Slide the nose cone back out and let dry.
Sand off the raised CWF ridge with a block.
The nose cone shoulder lip will be stronger and the edges sharper.
