In my excitement, I neglected to explain what Bertha is, exactly. She’s a Brown & Sharpe 6" X 18" Visual Grinder. You can procure your own on eBay, of course. The go-to source for all your heavy industrial equipment needs. Watch those shipping costs, though! They’re a killer.
Once you have one, you can start grinding carbide to specification within 1/10,000th of an inch, like all the cool kids! N assures me you can grind other things, too.
