With a little more than a week to go until I start fine sanding the body, I tackled the fret leveling.
Overall, it went pretty well. The big lesson learned: tap the frets down with a rubber hammer to make sure they are all seated properly before doing any filing/sanding of the frets. My initial testing with the fret rocker had a lot of clicking happening on a large number of the frets. By tapping the frets down a bit, I immediately eliminated most of the high spots.
I bought a cheap kit off of Amazon, but it worked pretty well. The rocker was the only component that was virtually unusable due to not being perfectly straight on a couple of sides, but I received a much better quality rocker that was combined with the notched neck level. Still, my next lesson learned is to go ahead and spring for the better quality tools for future builds.
