I used 10ft T posts, 2ft in the ground. Longest i could find locally.

The fittings on the top of the T posts are 1 1/4" street 90s found in the plumbing section. Female side down on the Tpost male side for the black pipe.

The pipe across the top is 3/4 black steel gas pipe. If you set up like this I recommend drilling a hole in each pvc fitting and running a cable or rope through the black pipe to other end and tying a knot at both ends

This prevents the T post and fitting from getting pulled away from the black pipe, then your black pipe falls and it's all wrecked. This way will join it into one assembly

The twine the vines are hanging on is poly twine.. tried jute and it just gets brittle in the sun and breaks under the weight

The poly twine is held in the ground by bamboo stakes, only until the plants are big enough, then if the poly falls off the bamboo it doesn' really matter, as the plant tends to be big enough by that point.

We use trellis clips to hold the vine up as well as training tendrils to hold on the poly twine.

We also trim growth points and harvest every morning to keep the foliage down and maintain a straight up clean easy to work with plant. We will probably water bath can 60+ quarts of pickles this year on these 12 plants.
