I’ve bored my 2” cylinder and honed it to the point where it doesn’t seem to be getting any smoother. It is very smooth to the fingertip, but I can see rather coarse looking hone markings, that can barely be felt with a fingernail, I was using a 220 grit, 2-7” hone. I am thinking bore needs to be smoother,but I’m not sure if I should look for a finer grit hone or cast and turn an aluminum lap. Is a crosshatch pattern needed on the bore of an experimental /hobby engine? Can anyone describe how smooth bore needs to be?
