Re: 1/2 emt Conduit Arches
I've read of people using 1/2 rebar 8ft long, pound 4ft into the ground then slide the arch onto the remaining 4ft slightly angled piece. Lots of work to pound 4ft into the ground but this gave lots of stability. I haven't done anything this large to need some support like this but it's in a thread somewhere.
