So I'm planning on building a down-flat-down kink rail. For lengths I figured I could do 7 feet down, 5 feet flat, and 7 feet down. Something I'm not sure about is the angles of the kink and how tall the supports should be. Any ideas?
I used to build staircases and handrails and the perfect angle (comfortable to walk up) for a set of stairs is 36 degrees but it depends on the type of rail you want to ride. As posted above I would say 30 degrees is a comfortable angle to ride.
