Anyone ever done this? Bidding a job where I need to go past a few utility poles replacing 8" clay tile with 8" SDR 26. Will be to close to poles to open cut past them. So was thinking I would probably stop and leave 7' of material on each side of pole and try to just push the 14-15' of SDR through. Any tips or suggestions on this idea besides a bore machine. Bids are really tight on these projects so anywhere I can trim some I need to.
