Quest Intruder Kit Bash, Part 9, Joining Two Rounded Leading Edges

Joining two rounded leading edges can be tough.

How do you sand a rounded edge in a tight corner?

Round the smaller (forward) fairing piece leading edge first. Leave the leading edge of the wing fin square for now.

Then glue is to the (still square) larger wing fin.

My sanding block is at a 45 degree angle.

Round the wing leading edge while feathering the inside corner.

Don't sand hard into the corner.

Here's the finished round leading edge with (hopefully) a smooth transition between the two pieces.
