More progress progressing forward! Latest feedback from the CAD people is this rendering which shows the skeletal sections under the sheetmetal body to verify fitment. What you see it's what I'll be getting out of wood, both horizontal and longitudinal. All parts will interlock and they'll be a keel down the center foot rigidity as well as alignment proposes.
This is a snapshot of a video they sent me, but I'm technologically challenged with trying to upload this tip YouTube. But fear not! Videography at it's finest will be forthcoming!

Cheers
