Still trying to figure out the cores. I’m thinking of them being horizontally prestressed to distort less from the movement on the road, if that is even possible. It’s boring to go for the most dumb solution – making them THICKER – in any case. Maybe I needed a bit of brain-freeze today in order to be fresh tomorrow.
EDIT: Haha, just saw Anny’s post. Collective brain-freeze! Very encouraging for the project!
