Estes Aries SST, #1927, Build, Part 167, Adding The Second "Finlet"

I drew a pencil line for the second finlet by sighting down the nose cone tip.

This seemed iffy, I matched the straight angle by matching the knife angle to the finlet in the nose cone.

Removing the finlet you can see the slot that was crushed into the balsa. It's actually pretty clean, a tight fit.

The second finlet is pressed into it's slot.

I was lucky - the alignment is good.

After adjusting the height of the finlets, there was a small gap at the bottom of one slot.

A wedge of balsa was cut and pressed into the void. The edges of the finlets should be rounded.

Here's the two nose cones (balsa above the 3D print) compared side by side. If the balsa cone were filled and painted I doubt you could tell the difference.

They are the same length, there is a little photo distortion.
