What's new

The superiority of lapping films.

As children, we all learned the pecking order of honing hierarchy:

Right there: you can clearly see a simple sheet of 3um lapping films beating rock (looks like some form of nagura, probably cost $300), and also illustrated is the fact that after ordering your 11x13" sheets of lapping film from thorlabs, you will need to cut it with a pair of scissors.

Sorry, rock rubbers, that's just the way it has always been....

Just when I had the feeling that the ratio of Jnat threads to Lapping Film threads (usually 33:1?) was getting out of whack again... Seraphim to the rescue. :001_cool:
 
By this logic the film will be destroyed by the razor and the rock beats the razor into sharpness.

Last time I checked I was using the rock on the razor not on the film.

I agree rubbing the rock on the film might cause the rock to lose, but rubbing the rock on the razor the rock wins.

So if we played Rock, Paper, Straight Razor, Lizard, Spock... does that mean that you always win by default?

Love the reference

Scissors cuts paper, paper covers rock, rock crushes lizard, lizard poisons Spock, Spock smashes scissors, scissors decapitates lizard, lizard eats paper, paper disproves Spock, Spock vaporizes rock, and as it always has, rock crushes scissors.
 
I am going to try it someday


For now, doc226 and his rocks win, for me atleast.

There seems to be a lot of different papers, sources.

Where is a good place to get it?

Amazon had a multi set down to 1 micron cheap, but if I understand, you need 0.3, maybe 0.1

Anyone care to share sources, prices?

Thorlabs

No need for uber-grits. I suggest going to 1um and stopping there.

A Jnat edge is much coarser than that anyhow....
 
Again, we are not rubbing the paper or the saran wrap on the rock.

Correct.

You may finally be catching on.

Just like in third grade: "paper covers rock"

Some like their lapping paper on marble tiles from Home Depot, others prefer precision granite from Woodcraft.

Either way, paper covers rock.

and beats it.

You are correct but.....

Last time I checked we want to beat the metal thingy, to meat the metal thingy you need rocks.

Rocks win.

It's called a pair of scissors.

Scissors are for haircuts.

If you want to sharpen your scissors, go right ahead, Rocky.
