I was assuming that the interior leads would be 1/2 inch (the visible lead on the outside - not the core). In which case my calcs will be off obviously. 1/4 inch feels too small in my head to be plausible. Maybe that's me paying too much attention to what the 100% scale image looks like and I'm editing my memories of the real thing to fit. It's just that on my 100% image the interior leads display on my 1600x1200 resolution monitor as about 1/4 inch wide in real terms (which probably bear no relation to actual size after the conversions it's ben through after coming out the camera as a RAW file).
