Ok so I got my hands on a few vintage blades and attempted to start hand sanding them. I have never wet sanded anything before. I bought grits from 80 up to 2000. I have read a few threads and heard some guys advise not to move on to the next grit until the scratches from the previous grit are gone. My question is if each grit creates new scratches how do I know when the scratches from the last grit are out? I have been wetting the blade and the sandpaper and going to town. I got up to 1500 grit. The blade is shiny but alot of scratches so I am assuming I have to go through the grits again.
Can you guys give me any good tips for hand sanding so I can get a mirror finish. Should I use just water or some sort of oil? Should I sand in circular motions or just back and forth? And what about the scratches..how do I know if the scratches I see are from the new grit or the old? Any help is really appreciated!! Thanks fellas!
