In the process of moving to my wife’s grandmother’s place (or rather, as a result), I inherited both workbench and bench grinder from previous generations. How said generations had attached and safely used the grinder is a bit of a mystery because the grinder was just bolted to a loose chunk of 2×8 and I have not bothered to ask the other generation for their wisdom. (I keep forgetting.)
But no matter, said I, for we shall conserve bench space and be ingenious and clever all at the same time! And so I was.
