Getting First Rail in Place

Getting the first rail in place was a bit of a scary proposition. I decided to go ahead and use the forks with another purlin clamped on it to get it to the necesary height, but it's still rather scary getting it close to level where there's a chance of it rolling forward off the forks. The bucket would have let me get the base higher, but is even less stable when it comes to keeping things from sliding off.
