And then ya' slap on some varnish , or shellac, or whatever, and it fills in them there tiny scratches anyhoo..........
You will hear a different opinion from everyone, but here's mine: 180 g is the max grit I go to on wood - RO each step 100-120-150-180, then 180 on a cork block for one last pass by hand, with the grain.
EXCEPT when I have a multi-step finishing schedule, as per when I am doing A+C finish on QSWO. Then I stop at 150g. shellac sealcoat, dye, shellac sealcoat, gel stain to color the pores, shellac sealcoat, varnish x 3 - 5 coats. AIn't no stinking scratches gonna survive all of that.
EXCEPT on the end grain, where I want to seriously inhibt dye absorption. Then I go to 320 to burhish the wood, and keep the color in-line with the face grain.
When I started woodworking, I didn't know squat. I have progressed in 30 years - now I do know squat.
