Yep, planning on a small crane. Not sure this type of flange is ideal for a
buried pier footing. I've not found specific details on those beyond
conceptual, though.
Also planning to fabricate a cross brace inside for rotator and also for thrust
bearing, and perhaps a fiberglass cover... Unless I can find something field
tested by others. Thanks for the reply.
