Can I go from 80 grit to 220 grit?
Flexner generally starts at 80 or 100 grit and seldom goes past 220. He prefers to sand to 180 when applying a film finish (shellac, lacquer, varnish, conversion, or water-based) and 220 when applying a thin oil finish. Sanding to 200 grit and above will polish the surface and hinder pigment-stain penetration.
What sharpening stones does Paul Sellers use?
The grit I suggest is 150-grit. I found that the 250-grit diamond plates soon lose their aggressive abrading quality but that it is still highly effective as a finer grade (somewhere around 300-400 would be a good estimation).
What grit of sandpaper removes scratches from wood most efficiently?
So when you make coarse scratches in a wood surface—say, for instance, 60 or 80 grit—the fastest way to remove those scratches is with a medium grit: too large a grit (only slightly finer than the paper in your previous step), and you’ll be adding needless work; but too fine a grit, and you could sand for hours and …
What is the best stone to sharpen chisels?

How much grit do you use to sharpen a knife?
Whetstones come in a range of grits: Less than 1000 grit is typically used to repair knives with chipped edges, 1000 to 3000 grit are used to sharpen dull knives, 4000 to 8000 grit are finishing stones and are used to refine your knife edge.
What’s the ratio of fine grit to coarse grit?
After discussing the topic of grit coarseness and fineness we decided to come up with our own chart. Since one person’s “fine” and one manufacturers “fine” may mean something completely different we established a 1 to 10 grit chart with 1 being the most coarse and 10 being the most fine.
What kind of grits do you use on Arkansas stones?
Given the Arkansas stones are a natural stone the variation is to be expected but it certainly made making comparisons challenging. You have to use an average of the scratches of both types of abrasive to make a comparison. We also looked at the apex of the various blades to help in estimating the effective grits.
What’s the difference between 1 and 10 grits?
Since one person’s “fine” and one manufacturers “fine” may mean something completely different we established a 1 to 10 grit chart with 1 being the most coarse and 10 being the most fine. This allows you to better understand what each grit is used for and make a more educated buying decision.
