Ciao Simone,

I'd like to use sandpaper to rough steel plates (tricky work using the file, and I haven't got a lathe...): which kind do you think is better to use? A fine or a coarse one?
If using Sandpaper, use very coarse one, minimum grit80, up to 40. ("very coarse" for a toolmaker, but quite normal for a carpenter )
Gruss
Hans
