Unpopular opinion: I switched from a standard 4-inch grinder to a 5-inch model for weld prep about six months ago
The extra inch (and the right cup wheel) cut my prep time on a big tank job in half, honestly. Anyone else find a small tool change made a huge difference in your daily grind?
Wait, you were using a 4-inch on a tank job? That's wild, man. I can't even picture trying to prep a big curve with something that small. No wonder the 5-inch felt like a miracle, you were basically polishing it with a toy before.
