Today we're sizing this ring down. But if we were sizing it up, we'd be adding a piece
of metal. So we use some of the same techniques and principles as we were just using. We would
measure precisely a length of metal that we want to put into the ring. I already have
this set up from one size, so for the sake of argument. I would scribe a one size mark
into it. Then using the same technique I used to cut a size out of that ring, I would cut
a piece of metal that was one size long. Now of course we would only cut the ring once,
not twice because we're trying to add some metal. Then we would take that small piece
and wedge it in here just tight enough that it won't fall out. But loose enough that when
we apply heat, the heat isn't going to force the ring to shoot that piece of metal across
the room. This is the time when it's a definite benefit to have a laser welder because you
can actually tack weld the piece of metal into the ring to make sure that it doesn't
fall out. That's a luxury that's only available above about the fifteen thousand dollar mark
for tools though.
