After assembling six of the frames for the outer boom I cut four pieces of 5/32 channel a scale 50' long for the horizontal members and also two scale 50' 3/16" I beams for the crane rail support. Mark these parts off in 10' increments and carefully assemble the whole structure, keeping everything square. Using .030x.060 strip add the actual rail to the rail beams. Take 3/32 angle and create the top diagonal bracing as shown. And finally, using .060 angle create the side vertical and diagonal framing as shown. I've included an in-progress photo of the pier - tracked and in the process of paving.

Jim,
How are you doing the track in the pier and your cement? Looks good.
