bending conduit for low tunnels
I'm seeing some posts about using pipe benders, making homemade forms and buying a pipe bender off of that seed company website. Mother Earth News even has some sort of bender using wheels and a crank (homemade) What is a cheap person to do? I think shipping will kill me here in WI on ordering the premade one (i may splurge). Can i use a conduit bender? I've seen where people make 3 60degree bends...is this not a good style of tunnel?
I'm going to shoot for 2 low tunnels to begin with...hopefully 2 24ft long ones. I bought a bunch of 1/2 inch EMT today (1.44 a piece).
