Built the T's out of 4"x4"x8' pressure treated posts, with a 4' section attached to the top with two L brackets, and two T brackets.
Painted them with outdoor paint to make them look a little nicer, and to make them a bit more weather resistant.
Dug the two holes - about 12" diameter, and about 26" deep. Used a 30" plastic post sleeve that the post will slide into, and will be 4" above grade. Helps prevent water from rotting the post, and also can remove the post without digging up the concrete footer.
Put a inch or two of drainage stone at the bottom of the holes. Used a 50 pound bag of concrete in each hole.
Set the post sleeve level and poured the concrete and let set overnight.
Backfilled with soil the rest of the way
Wasn't so easy to slide the posts in. I had to stand on a ladder and hammer in with a sledgehammer. So much for the theory that I could slide these posts out in the wintertime. Oh well.
Strung up the jute twine from the eyelets in the planter boxes through the eyelets on top of the T. Right now the excess twine is coiled on a rope cleat I screwed into the side of the T. But I will be building a second higher post to run the rest of the line up too. Hops need a natural line to grow on, so that the plant can grip it as it climbs, hence the jute twine: http://en.wikipedia.org/wiki/Jute
Minimal training needed. Just wrapped the bine around clockwise twice, and it did it's own thing from there.
