Dunigan Bros, working in East Lansing, MI, recently completed this 48" bore in only 5 days. The kicker? It was 330ft, and completed ON line and ON grade. Only the best of the best can maintain these production rates. In addition to knowledge and skill, this requires the right equipment and intelligent application of technology.
By using a Casing Compass, Dunigan Bros never had to pull augers to check line and grade. They got instant feedback on the pitch, roll, and alignment of their casing, allowing them to complete a gun barrel straight bore, which made for easy work for their work horse: A Michael Byrne Mfg 72-1.5
