I have a bit of setup to do I think. I used a fairly short board and had a bit of snipe on either the leading or trailing edge, the board length may have been an issue. I will play around again today and use a board of appropriate length and pay closer attention. I was surprised that the head left very slight waviness across the board. I think it is a product of the helical cutter head and the curved shape of the cutters. I doubt there is anything I can do about that. And it is very minimal but I can see it and feel it which makes me wonder about comments I have seen saying people get glass-smooth finishes. Well, it is glass smooth but not perfectly flat, maybe one-thousandth of an inch variance which really isn't much. The little piece of wood was fir so fairly softwood. Hardwood may be a bit different. That said this little beast is so quiet I needed no hearing protection and could hear my radio clearly over it while running and even while in use. Literally quieter than a fan. With the dust collector on you can't hear it running. All in all, I had hoped glass-smooth meant perfectly flat not just smooth and slightly wavy, it is going to save me a fortune in time! And a quick pass with some 220 on a flat hand sander will knock it flat very quickly.
