I'm getting ready to make some vertical frames from electrical conduit (ala Square Foot Gardening), and I am wondering about strength.
My conduit will be coming in 10' lengths, and my raised beds are about 2' high, and 4'x12'. I intend to put the frames along the long edge of the beds.
To avoid cutting the conduit, I would like to use 1 stick for each side, burying the end 1-2' in the ground, having 7-8' of height, and then bending the last 1' over to start the top crossbar. If I do this on each side, I could connect the sides with a 10' stick and have the whole contraption be just over 12' long.
My question is, do you think it will be too weak having the two connections along the top crossbar? Would it be worth the hassle to have the sticks cut, so that I am either having 1 connecting at the center of the 12' span, or should I also use a center support, and a T connector at that 1 connection in the middle of the 12' span?
If I should cut the conduit, how do I do that? It is EMT 1/2" thin-walled electrical conduit.
THANKS!!
