Lawn Dart Rocketry SLAT/S Build, Part 2, Fin Fairings

Here's a cross section drawing of the model. The instructions call the assemblies "Fin Pods".

The fin fairings are interesting, made up of a three piece laminate.

There are three pieces on each side so cut out six in total. In the top picture is all six stacked up for uniform sanding.

Two of the three pieces on each side are cut for the fin tab fitting.

The sides of the middle notch is easily cut out using a single edge razor blade. Cut down to the long , straight bottom of the notch.


The longer center line is cut with a knife and straightedge.

The top piece notch is a bit trickier. This is one of the few times I'll use an X-Acto #11 blade instead of the break-off blade knife.

Cut the short sides first, then the longer middle cuts.
