Estes Semi-Scale Saturn V, Kit #K-39, Part 13, Filling The Upper Body


The balsa shoulder on the nose cone wasn't sharp.
CWF was brushed on just over the shoulder lip. While the filler is still wet, push it into the body tube and turn. 
This raises a bead of filler around the shoulder lip. Remove the nose cone.


After the filler dries, the sides are sanded with 400 grit on a block.

When this nose cone was machined, it had a slight dip in the sides.
On the left, the pencil lines show where the balsa was high. I had to apply more filler to the center low areas.

That horizontal pencil line below the command module is a reference line for sanding a straight line around the body.


The nose cone required a third pass of CWF to fill some low areas that still showed under a bright light.
