    Cut the driveway very neatly and replace the section that's cut out with nice cobblestone. That's what I usually do and customers are usually very happy.

    if done correctly, it can be done in minutes but you have to know what you're doing. :rolleyes:

    You can do a 20' 2" bore in minutes with a rod and hammer? How?

    you never mentioned a hammer in your statement, it can be done if you know what you're doing though.:)

    I agree it can be done, but I still think it would take half a day. The rod has to sit flat so a trench has to be hand dug(he doesn't want to rent any equipment) for probably 20' since a 2" metal rod isn't too flexible. And good lord that would be quite a few wacks to get it 20' under. And then how do you plan to pull it out?

    I own a boring unit, and a 20' bore would take 2 man hours if everything went perfect and if I did not hit rock.

    If I didn't have own boring unit I would rent one or sub it out. I hate making cuts in concrete or asphalt especially if it my own property. I can't imagine what my guys would be thinking if I pulled out a 20' pipe and told them to starting hammering.

    find an old time underground construction worker, if you're nice to him he just might tell you what the trick is.

    I am interested to know the trick, but since I have a boring unit I doubt I will be doing many long bores by hand.... been there done that... and its a hell of alot slower than a machine.

    I talked to an old timer who told me about a process he called "spooning". It was some kind of U channel connected to an air hose and the tip would chisel the soil and the air would blow it back out the whole.

    My brother hammered a 5" steel pipe under a road to connect his two fields using a demo hammer on his mini ex.
