I have mentioned a set of trellis' that I built for pole beans and cucumbers in a couple of posts. I thought it might be a good idea to show you all what I was talking about in case some of you might find something similar useful for your garden.
The making was simplicity itself. The stands are made from 2x2's or similar scrap, each of the legs is 8 feet long. I bored a hole through each of them a couple of inches from the top and put a section of all-thread through it with a fender (extra large) washer and a nut on each end. The 2x2's cost me a buck and a half each; the all-thread (36" piece of 5/16"), nuts (8), and fender washers (8) came to another three bucks.
There are pole limas and cucumbers planted where each leg contacts the ground.
I made these after seeing how a friend of mine grows his pole beans. He uses bamboo tied together at the tops and stood up in Tee-pee fashion. The bamboo he used was quite tall, probably on the order of 12 feet, and he tied about 10~12 of them together. The base was about 6' in diameter so you quite litterly walked into the cone to pick. Cool!
On Edit: I used 4 legs because the ground is flat. If they were needed on a hillside or other uneven plot they could have been made with 3 legs.
