Default Endless lathe chips (re-adjusted the clutch on a Clausing 6913 lathe)

I finally got around and re-adjusted the clutch on the Clausing 6913
lathe. (13x48). The clutch was previously slipping and I could only
make the lightest of cuts.

Now, the clutch no longer slips when engaged, and can still be
disengaged, and I can take much heavier cuts. And what I like the most
is that I can again use power feed.

The problem I had with one piece of metal, is that when I cut it with
power feed and a carbide insert, it would make an endless chip, that
warps and gets everywhere, and it seems to be unsafe. How can I ensure
that this chip breaks?

Chip breakers rely on a given amount of feed in order to function properly.
Rule of thumb is to increase feed when a chip doesn't break.
Do not expect a chip breaker to function with light feeds, or shallow depths
of cut.

Good points. And sometimes, don't expect them to work at all.

If Iggy is dealing with some nickel alloy (like stainless), a higher
feedrate will work-harden the chip and help it break. If it's some
dead-soft low-carbon steel, maybe, maybe not.
