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?

i

1. Buy inserts with a built in "chip breaker"

2. Buy tool holders with an external chip breaker.

With the proper grind/chip breaker..your chips will come off the
cutter in the shape of the # 9

And yes indeed...while pretty..they are unsafe as hell. Depending on
the thickness and the metals...they can pull you into your lathe and
sever limbs/fingers etc etc

Really?

"Hurt" aint the word.

For Liberals, the truth is like salt to a slug.
Sunlight to a vampire.
Raid® to a cockroach.
Sheriff Brody to a shark
Bush to a Liberal

The truth doesn't just hurt. It's painful, like a red hot poker shoved
up their ass. Like sliding down a hundred foot razor blade using their
dick as a brake.

They HATE the truth."
