AFTERTHOUGHT: Drilling the 48" deep holes for concrete piers for foundation
Having completed drilling the footings for the sauna
building, I learned one thing. It is hard to control the speed, angle and depth
while running the gas auger. You take the effort to carefully mark all the
places the holes need to be drilled, but you get the auger positioned over the
markings, start it up, and WAM! The auger goes where it wants to go—it’s possessed.
Especially if it encounters rocks or roots, the auger can easily change
direction. One thing I would suggest is, prior to drilling your marked holes, clear
a little bit of the dirt with a shovel. You don’t have to go deep—about 6”-12”
should do, but you will be able to be a lot more accurate with a shovel and
once a small hole is dug, it will be harder for the auger to jump out and miss
the mark when you start to drill.
