Speaking of next time I ride it, I'm not sure my DIY fix for the seat post is holding up. I think i need to do a better job.
Options:
A) redo the steel sheet wrapping, but with smaller segments to avoid friction limitations. Maybe some angle profiles in the wrap too.
B) model and CNC some aluminium plates to go from the rack mounts to hold the seat post. Complex 3D modelling (can prototype with 3D printer)
