Worth, I think the gothic arch idea sounds good.
The following paragraph isn't done in any type of arch - just straight T posts and rebar. There are 7 of each per row.
I'm not sure the 3/8 rebar is strong enough to support the weight of foot long beans? I put in T posts today 5' apart in the rows (2 rows 4' apart) I have seven 8' - 3/8 rebar. The soil is so friable I was able to pull the rebar a foot into the ground easily. I wired the rebar to the T posts in 4 places each post. There's no strength on the rebar above the T posts whatsoever. I put it in this way just to see it, and it won't work. The T posts are 5.5' high and would support the pole beans easily.
I know I mentioned most of this earlier in this thread, but today, I put it in and saw that it doesn't work. I'm not sure 3/8 rebar is strong enough to make any type of arches?
I found this video

We are trying not to spend any extra money because we are finally more than keeping the bills paid. It's good seeing "Paid Off" starting to happen.
