Picked up 3 sections of the fence post and caps last night at Lowes. Will be working on my set up. Some mods to the mods:
Lockable access on both sides.
Use I-bolts thu caps as handle/locking device.
Use wire cable back to threaded rod on one side and pad lock on the other for securing.
This is a great mod/thread, will post pictures when done.
Thanks for all the great ideas.
