Is this paper there to do what I think it is?

Watching a video trying to learn a bit more and I see the fellow place this paper with a cut out on his workpiece.

Behind it is a steady rest.

So is the paper to keep swarf from getting on the workpiece and then getting stuck in the bearings?

It is clever, and not likely to do much damage if it get caught (other than potentially throwing swarf everywhere).

It is interesting that they’re protecting the shaft with copper covers on the 4-jaw chuck, but putting a real burnished ring on the shaft where the shaft is running on the bearings.

Swarf protection, I use a boxboard shield for the same thing.

My guess is the burnishing ring from the bearings isn't as bad as seeing serrations from the chuck jaws.

I think that with more rigid material the soft jaws in the chuck make it easier to indicate the part.

could be no need to remove them and like me, too lazy to take them off

I vote for swarf gaurd. I use cardboard and cardboard boxes for that all the time.

Another cool use of cardboard!

I use cardboard as chip traps on the mill all the time. But I never thought about doing it on my lathe too.

Today, I was hogging away metal for a project I am doing right now, and it was slobbering hot chips at me like horny teenage girls used to.

They make me uncomfy......

I remembered my mill, and voila. Instant relief!

I don't remember cardboard when I was a teenager.

As that post says, I use them extensively on my mill. I've added a few more cardboard chip guards for the lathe since that post too. Dirt easy to add cardboard chip gaurds to a steady.

On a lot of old lathes, it is pretty common to see the steady rest has been smashed at some point and repaired. I haven't seen it happen but I'd guess that swarf getting in between the work and a finger would be a leading cause. So the paper looks like a great idea to me. Plus, I've seen Curtis from Cutting Edge Engineering doing it on Youtube.
