Doc, its all squared off for concept only. Once I chose a design I will then modify it for aerodynamics and aesthetics. There's no point in spending another 20-30 minutes on each model to make it look pretty.
Edit: and what do you think about the welded bracket idea? I was actually thinking that if I had you make those brackets then I could even forego making tall stanchions since the brackets would just need to extend about 3/4" below the bottom of the rack. Then I'd just machine some platforms out of steel to give the rack a level surface instead of the angled rail. Ill draw that up tonight after my bike ride.
