Estes Klingon Battle Cruiser, #1274, Build Part 9, Adapter Shoulder Filling TIP

The balsa adapter shoulders aren't sharp but rounded over.
I've already done the wider base of the adapter, this post will show how to build up the top.
On the left side, CWF has been brushed just over the lip.
In the inset picture, the BT-5 is slid down, pressed and turned into the wet CWF.
This makes a raised bead of filler. The bead is wider than the shoulder lip.

Turn and raise the tube.
You will end up with the raised bead that will be sanded down after it dries.
Pressing the tube into the filler makes a very sharp, compressed edge.

I also do this on most nose cone shoulders.




And after sanding - 
I use a sanding block to keep the taper flat.

Look close at the bottom lip. You can see where the filler was left a little thicker. The edge lip is thicker and more square. Right out of the box the adapter lips were rounded and not a good fit to the body tube outside edge.
