more on my tunnel building

So I still have the 14 foot wide greenhouse film (in the package still) for a two bed wide low tunnel. Now that I buy EMT and bend with my foot I figured I could just take 2 and bend them into a U and make it a 14 foot half circle. It will leave 6 extra feet though. What is the best way to connect them? Being they will overlap say 4 feet and 2 feet in the ground can I just bind them together with duct tape so they overlap on the middle/top?

I put a link below to give you some ideas. I ordered my bender from lost creek, and I like the company. I'm sure there are other places to buy similar products.

get emt that is the next size up from what you got and stick the ends that you want to meet into it and drive a couple of tek screws into it.

Similar to Randy, I was thinking using a smaller diameter piece and fitting it inside the two you're joining. Use tec screws in the side opposite where the plastic will lay. Maybe a little less wear on the plastic this way.

The extra plastic overhang is a little overkill, but will give you plenty of edge to cover with dirt to 'batten down the tunnel'.

OK so I will get the 3/4 inch tubing and screw together with the screw on the inside. I definitely don't want to rip anything! I will leave some inches on each side for weighing down.

Yesterday I re-erected the tunnel from last fall. It will go on my early sweet corn.

I also started working on the tunnel for the 14' greenhouse film for tomatoes. Early tomatoes this year are going in 5/9! Eek that is late.
I bent the EMT but stopped there because the ground was too hard to push them in deeply. Now it has rained a lot so I will finish tomorrow. Don't get mad anyone, but I will probably just fasten them together with duct tape.

In the pic they are just barely in the ground. They will go in several feet.
