Not to belabor this but, even though the discs are .025" there's enough wobble in the mandrel, chuck, and the operator's hand to dig a trench that's considerably greater than 1/32". Arnie says he built a fixture that allows for a straight line. That probably works just fine. But I don't believe, having tried it myself several times, that a person can etch a groove freehand to the width and depth required by USGA rules. But then, I ain't a vascular surgeon.
