Stone columns can be easy or they can be difficult. Depends on the material: how well does it work under the chisel? How much of it is available? The techniques are simple and fairly standard.
I really do love my job. One week, I’m on a roof nailing down shingles. The next, I’m back on the ground laying stone or brick. Stone masonry, though, will always be my favorite. I come from a long line, stretching back for centuries, of stone masons and cutters. Very skilled they were judging by their surviving work. One example is the house in which I live, built over a century ago.
I have no doubt that they could have done stone columns with their eyes closed. I’m not quite that good or nearly as efficient as they were.
