do you want the ramp to be movable so you can skate just the box, cause if you don't then i would suggest using coping to make it a smoother transition. you could always have the other side be the box you know

no, I want to be able to move the ramp, have it a completely separate thing, so I can use it for wallrides and stuff too. Plus I like the sketchyness of not having a round coping
