"shaving" heads
Gee, I read all of these remarks about the use of this tool and that one. I also read of some cutting materials being better than the other one. Some methods are better than others.
Well a few years back I purchased a cast iron Winfield head that, I discovered later, been welded across the water tube area on the top. This was to repair an exterior crack. Engine side looked okay but the head was warped .045. Not knowing I was doing it wrong I milled it with a 2" diameter indexable carbide end mill. Taking it off in light cuts, dry, I ended up with a flat surface, no measurable mismatch in tool mark patterns using a .0005 indicator.
Of course I had indicated the Bridgeport head in beforehand using the same .0005 indicator on the end of a 6" arm.
