Picked up a 1.5” drum sander-decided against the rotary file. Used a coarse drum on the cut, which quickly cut away the excess (on the left side, think I’ll cut closer to the line to begin with). When I got close to the edge of the cut, I switched to a fine sanding drum. Then I used a 1” scotchbrite wheel to finish up. Looks so much better than the night before.
