New Way Nike Ajax Build, Part 13, Gluing On The Upper Fins & Tunnels

I used a tape wrap for a baseline when gluing on the upper four fins.

Three fins below, four fins on the upper body. 

It's a bit confusing as to how they line up, 4 over 3.

The tunnels were set on the tube centered between the upper fins. Trace their top and bottom ends with pencil.

In the right side picture, notice the tunnels extend just over the top of the tube. 

After the glue dries,

Sand the overhanging tunnel ends even with the top edge of the tube.

This will make a tighter fit with less of a joint gap between the tunnels when the nose section is slid in.

Here's the front end showing the ends flush with the end of the tube.
