Well, you're going to have to dig a helluva pit just to work in, plus elbow
You might try dirt auger bits, used for digging post holes. They come in
2-3", up to 12" or so. Hoffman.
Since you might need a rotary hammer anyway, might as well just make an
adapter and sectionable extensions, for both the auger bit and a carbide
tipped drill for any rocks, etc.
. My big Bosch is an SDS max, w/ variable speed, and not a very fast rpm,
but a good wallop, which would probably be helpful even in the augering
You will have to do some welding, which can be tricky w/ tool steel alloys,
so you might want to have a knowledgeable guy do it, or get recs from sejw.
The extensions can be regular black plumbing pipe, w/ couplings.
Hopefully you won't have to put anything in 'reverse". :)
