I'm happy with the outcome and am working on some better designs right now. I figured out that the bowing was from the tweezers pushing against the bottom of the scale. This is a somewhat flexable material, so I guess that's going to happen unless you give it more room than the factory scales. I'll probably just leave the toothpick & tweezer slots out of future designs anyway. The surface also seems like it will break in and be less rough over time. You can polish it as well. I like the alumide. It feels like it should be brittle, but it's flexable. It's strange & interesting.
