The notches were for a "keyed fit".
They were more for the Virtual Kool Shade version of a build which would have been cast from very Hi-Rez 3D print.
Ultimately we went a slightly different route with the VKS but they do go together now more like a hero kit (with real Kool Shade) rather than a single piece solid cast wing. The WingStars attached separately over the VKS cast portion/core. As I said these were made almost 10 years ago.
At the time we could not 3D Print a large enough section of VKS but within just 2-3 years later that changed... it got a bit cheaper to print too.
I do not think there would be anything to gain trying to "key' the real Kool-shade... you would only end up mutilating the louvres.
It would be interesting to test if the Kool Shade could be cut effectively with a water-jet cutter.
Unfortunately, I do not have enough extra to spare for such experimentation.
Perhaps if I could get some of the modern stuff. It may make nice clean cuts without bending the louvers as with shears.
The water jet does have abrasive residue.; in which one might run the risk of scratching of the finish in places.
