Aren't those boring machines awesome?! I had one out to my house to run an electric conduit from my barn to the dock on my lake, then from my dock to my island in the lake. In the 400' run from my barn to the lake, they hit a large "obsticle" that caused a huge bend in the line. However, they were able to turn back and continue the line without doing it over. It is amazing how they can make the turns and still come up right next to a post on the walkway to my dock. /forums/images/graemlins/cool.gif
I found that when they made the run from my dock to the island what the max bend of their drill is. Being that the bits and lengths are so expensive, they don't like to lose them. Being that they were going under water (10' of water where they went), they didn't want to lose a bit. It would not have been possible to dig it out. Anyway, 15 percent bend is nominal, and 20 percent bend is max on what they had at my house. It is still amazing. They stayed 3' under the bottom of my lake and still came up within the 12" diameter circle painted in the grass on the island! /forums/images/graemlins/shocked.gif I thought that was awfully good since they couldn't trace the movement with their little detecting machine when the bit was that far under. The operator had to go by simple experience.
The company that did mine is owned by a good friend of mine. They have a boring machine that takes two semi trailers to haul it to the job site. They have a 48" bit for it and can pull 48" pipe. The bit (only the bit) for the rig was tens of thousands of dollars, and had a serial number of "1". /forums/images/graemlins/shocked.gif He told me that they won't do a job where they don't have the option of going after that bit if it gets stuck. /forums/images/graemlins/wink.gif I asked him if the entire rig cost over a hundred grand, and he laughed at me and told me that I didn't have a clue. /forums/images/graemlins/blush.gif I guess I won't be buying one of those for the ole shop. /forums/images/graemlins/grin.gif
Oh yeah, this guy is the same one who talked me into running a 3" water line back to my house from the 12" main out on the road. He knew I didn't want to be short on water back at my house, which is about 1000 feet away. Uh, a 3" water line provides plenty of water for one residence. /forums/images/graemlins/blush.gif I really don't need a pressure washer now, and when someone flushes a toilet (heck, they can flush all 7 at once) you don't get scalded in the shower. /forums/images/graemlins/laugh.gif It sounds like you should have plenty of water for about 50 or more homes or so from what I was told is needed volume wise per residence. I'm told that I could meet code for 15 homes with what I have! How many homes locations are you making?
