Thread: Synthetic progression end result?

Yeah it what I have been using for a couple of years now, I sometimes wonder if adding a stone right after 1k and before the 4k would set up a smoother edge in the end? I don't like using pressure in the lower grits and find myself using a lot of passes on the 4k to remove 1k scratches.

Using circles on the 4k will speed that up

I do the Lynn method of 40 circles with pressure and 40 circles without pressure then 10 or so X stokes. It does work great don't get me wrong. I just wonder if I did those first 40 on the 2k then next 40 without pressure if that would produce a more refined scratch pattern? Or if the truth is there wouldn't be much of a difference then I will let the theory go

I've wondered that myself, if you add the 2k time to the 4k time does it save any time and refine the edge more? I get a very mirrored surface after the Norton 8k and my finishers. I hope someone with a 2k experience pipes in with info

I like to add in my 2k to my progression a lot of the time. I use shapton glass 1k,2k, then either natural jnat or synth 4K, 8k, 16k and g20k. I do find it is really nice in finishing the bevel set if for some reason the 1k does not tend to be getting to where I like it before going to the 4K. It does save time but just going by the numbers it may save a 1/4 of the time going from 1k to 4K.

And about the pressure circles then no pressure circles. I've quite counting a long time ago going simply by feel and only when the edge passes my tests do I move up. But yes the no pressure would refine the scratches more.

And as a note sometimes I will use my 2k as my bevel setter.

My Shapton 2K (light green) works for me to get the scratches from the King 1K out, I use it often. If I am jointing the edge, this 2K will be the last time I do it. Then reset and move on to Norton 4K. I will also toss a King 6K in between the Norton 4/8.

The Shapton 2K seems to load up quickly. But a trick is to get a little coticule slurry going on the surface with a small soft coti rubbing stone. It still cuts like a 2K but doesn't load up, the slurry turns grey instead of the hone.

The 2K is also a bevel setter for me when 1K is not needed.
