Thread: Why lapping film rules

Well, you sent me on a web adventure trying to figure out what the heck lutos effect was.

Damn! Sorry I misspelled. Of course I meant Lotus Effect.
I mean, the water on the lapping film does not spread evenly thus not providing proper lubrication and cushion.
A little dish soap will keep that from happening and does in no way harm the lapping film.
Just be causious not to drop the razor, because the tang may get slippery

I got the .1 in yesterday and had to give it a try.

My Case Temperite has always been a little harsh so I put the film, didn't expect it to be adhesive backed, on a granite tile and sprayed it with water. I had to add a little soap to make the water spread as I was warned.

20 laps and it seemed to do better on the HHT. This mornings shave was definitely better.

I'm sure it will take more experimenting to get the most out of it.

As far as paper goes, what kind of paper are we talking about for use under the 1 Micron paper. I mean are we talking about just regular notebook paper or something with a little more cushion to it.

I think Seraphim originally recommended standard copy or printer paper.

Yesterday I finally took the time to do a "High Tech Hone" session

First many thanks the the two guys that sent me some 5-3-1 µm Lapping paper and the .1CBN spray to mess with

Method:

Base:
I went to the local Glass & Cabinet place up here, as they have been so generous with getting me Plexi sheets for my hones.. They supplied me with a piece of Polished Marble 4.75 x 9.75 x .75 inches... This made for a perfect base plate which I put some of the Silicone non-slip feet on..

Strop: I had read that if you are going to use the CBN on leather that Kangaroo was one of the best choices so having two Roo strops I sprayed one down and set it aside to dry

So now I am set...


The Razors


6/8 Wacker full hollow and an older Sheffield heavy grind, basically two polar opposites


Starting with both razors at a well set bevel off the 1k Chosera I went to the Wacker first and the polishing went fast, easy, and accurate.. The W&B was a different story it took more work to get the entire bevel even and polished...

On the 3µm the story was repeated as above


Moving to the 1µm I had cut a piece of Printer paper before hand and placed in on the Base then sprayed it down, the Lapping film went on with zero problems, and the Wacker took to it perfectly, the bevel and edge looked excellent under my 30x loupe..

Now the W&B that wasn't so perfect and I wasn't liking what I was seeing under the loupe, you have to understand I was being pretty conservative on laps and was watching the bevel develop as I went but this just wasn't working for this razor IMO

Anyway I continued through 10 laps on the CBN Roo strop and the 50/100 Linen & Leather


The test shave

The W&B first and with a short pass I pulled out, the edge was just not there...


The Wacker I shaved this morning with excellent results, just a beautiful shave...


I took the W&B back down to a Norton 4k the 8k and finished with my Coticule and the edge looks great and I expect a nice smooth shave from it...


Will do more testing later, the Wacker outcome was impressive

I find lapping film works best on high quality steel razors, cant speak for every razor but it works besk on my iwaski kamisori, a tamahagane kamisori and a heljestrand. We these razors i can maintain an edge almost indefinately using 1 and .3 mircon lapping, just a quick pass, strop and off you go again.
