Google is only your friend if you have a clue about what you are reading.
A scraper is a wonderful tool producing a perfectly cut finish with pores wide open and ready to fill. A great tool and a wonderful way to get the best finish... If you have the skill to run one. Few do.
So then you go to the exact opposite approach and advocate super fine sandpaper! Wood is coarse, even fine-grained wood is coarse compared to finish. So you suggest the coarse wood be polished with superfine grit. What happens is the wood is crushed down into the pores and it "muddies" the finish.
Coarse grained wood like red oak is not improved with sadpaper finer than 150 or so. By the time you get to black walnut 220 is pretty fine. The tightest Turkish does not need 320. Once the finish goes on and you are finishing finish and polishing it, then fine paper works wonders, but it is wasted on wood.
Polishing unfinished wood? Come on!!! Let's stuff as much crap down in those pores as possible and see just how badly we can kill that luster and ruin the perfect surfaces developed! Denim to polish!?! Canvas!?!
Lee, you are a really special individual!
And again... If I knew as much as you do about that I would be asking advice, not giving it!
