When we jump from full cap to cut cap to full were cutting off such a small sliver from the cap to the left and right that its not noticeable. If were talking a real tight radius, firepit for example, measuring is the only way to go otherwise you would be correct in saying its gonna look like a hack job. We just use best judgement, if its still going to look like a killer finished job doing it the quick and easy way were def taking that rout if possible.
There are two things to aim at in life: first, to get what you want;and, after that, to enjoy it. Only the wisest of mankind achieve the second. - Logan Pearsall Smith
