Estes Skylab #001973, Build, Part 13, Fin Fairings - Enough Already!

Here's what the fin slot looked like after fitting and trimming.

You'll know when you've got the slot right when the fin slides in (dry fit against the lower body wrap) and there is a straight line down the long sides of the fairing slot - No bulges or distortion of the fairing!

The rounded tip of the fairing overhangs the top of the low wrap. This overhang leaves a gap.

You don't have to fill this tip gap, it's up to you.

I mentioned about keeping some of the excess border from the vacu-form sheet.

Cut a slightly oversize piece, slip it under the fairing tip and trace with a pencil.

After the tip is glued on,

Cut and sand to the fairing. 

The picture on the right is slightly distorted, that tip piece is glued on straight.
