Turning Concrete on a Metalworker’s Lathe
OK. The concrete is aerated… Hebel.
But, it does turn easily and cleanly.
But it is concrete, and probably very abrasive, so I have covered everything in plastic, and used an old carbide cutter.
I needed to refine the dimensions and shape of the supporting block while brazing my 6″ vertical boiler, so I turned it. And it worked brilliantly.
