Left Lane Coal Roller at Large
So this is what I've gotten the surface to. I've used a carbide scraper, a .006 brass wire wheel then a piece of scotch brite against a 1" thick piece of ground steel as a sanding block. In two spots at opposite ends of the engine block just outside the fire ring I'm seeing some pitting which I'd like to eliminate but it is so fine it doesn't even catch my fingernail....at least not noticeably so. Thoughts??
