apply edges to ski, base last why not?

I want to build a full torsion box.
Rational being "not much" but also "why not" since we all decide to build for personal exploration reasons.
That off my chest, until modern times my familiarity was with old-school straight skis. The (cracked) edges were screwed on, and then the bases applied over the screws and flange, between the thin raised edges. During the 60's & 70's it was even possible in some cases to send your skis back to the factory and get new bases, or even bases and edges applied. IOW, the ski was built first, then the bottoms applied. EG, my ancient VR17's
It seems that modern user-built and small lot custom builds are all started by cutting our the ski shape in the (non dimensionally stable) plastic base, and then bending & gluing the edge to it, and building the ski on top. The edge becomes the control for the rest of the machining, including the sidecut.
Do large scale production builders use this same process?
Are the structural shapes of a production ski really defined by the base and edges, or vice versa?
If so, what does the "mould" look like?
I would like to build the shaped, pre-bent core with parallel carbon faces as one pressing. Then add on a fiberglass tube, topsheet and the base and edges as a separate pressing. What techniques were used for alignment in the past?
Thanks!
