Noris Raketen Aggregat - 9, Part 8, New Nose Fin Fitting
The top ends of the lower long fins were sanded flush with the body tube end.
On the left you can see the fin is just a bit longer than the body tube.
New nose cone fins were cut longer so they would go to the top of the nose cone, or closer to it.
On the left you can see the fin going beyond the tip of the nose cone.
The sides are wider than the lower fins. After they are glued on to the nose cone the low ends will be sanded to match the lower fin width.
The inset picture shows the inside tip. The nose cone top had a slight bowing out.
The fin tip was sanded to match the height of the nose cone.
Just the leading edge of the fins tops were rounded.
The nose cone had the primer sanded off for better adhesion.
After the fins are glued on the low sides will be sanded to match the lower fins. Then the rest of the leading edge will be rounded.
