I was so eager to start cutting, I had everything all set but the last detail - deck height. I had only eyeballed it, so the head was about .150" too far, with only a short focal length (1.5") lens. That's why it is cutting fat there, but the parts one that sheet are off by all of maybe 3 thou.. oh no!

I have all ribs 1,2,3 cut so far, two sheets of rib 4, the tip rib now. One almost done. I smell like a sugar shack from hovering around the filter exhaust all afternoon. (no worries, big HEPA filter and activated carbon organic vapour filter. Just a sweet burny smell.) Ah, done. 16 tip ribs, 5:54.
