This is the noisy, sparky, bad-boy method. An angle grinder with a diamond or abrasive cutoff wheel will slice through cast iron like butter. But be warned: it’s loud enough to wake your neighbor’s dead goldfish.
You’ll get a shower of orange sparks. It’s very rock-and-roll. Just wear goggles, earplugs, and a shirt you don’t love. The grinder can kick back, so hold on tight.
Pro tip: go slow. If you force it, the wheel can shatter. That’s a bad day.
Why This Is Fun
Sparks are basically indoor fireworks. Plus, you can pretend you’re welding a spaceship. Just don’t do it near anything flammable—your curtains aren’t fireproof.
