Alright, so my dad agreed to help me weld up a metal rail for our yard. I want to build a flat-down rail because it's fairly easy and I can get more into the technical stuff with it. I'm just needing some dimensions.
I'm thinking making it 2ft off the ground for the flat because I don't want it too high for speed issues but I also want the down part to be 270 off doable. I' think I'll make the flat part 12ft and the down 6, 8, or 10ft. I'm not sure, what angle should I make the down part go?
