i'm about to begin my first project on a forge, and since i have no tongs i was going to make a set of tongs using the blueprints on a website. i'm going to be using a peice of 1/8 by 1 inch stock thats going to be about 3 feet long and since i'm only going to be heating the ends i was wondering how far your hand should be from the glowing end of the metal (wearing some welding gloves).
