I did a bunch of grinding and clean up last night on the left sabaton. WHAT. A. PAIN! That forge scale just doesn't want to come off of 410. I tried a couple different grits of Gator wheels. When they're fresh they work OK, but they loose their freshness quite quickly. Then they're mostly just heating the metal. I tried soaking the plates in vinegar for about 45 minutes. The stuff just laughed at me. A note for the future- don't over heat 410.
