Estes Gryphon #7280 Build, Part 3, Engine Hook Prep & Fill

Here's the engine pod "hook" parts.

That long finger extension on one side of the hook is delicate and can easily break off.
Later in the build the launch lug is glued on the extension.





All three pieces were filled with CWF then sprayed with filler/primer. Normally you would simply glue them together and fill afterwards, but this is s how model. I had to have every inside edge filled and clean.

In the picture I'm filling the inside corners for a smoother look. I used a diamond file to get inside the corners.




I also hit the pieces with a shot of filler/primer before gluing them together.  I usually sand to surface leaving very little filler/primer. The two side pieces were only sprayed on the outside leaving bare balsa for a better glue bond.
Doing it this way also involved more filling later -
