Hi...Im testing with a norton 8k and a shapton 15k...
I was making some pyramids using both of them...
I lapped both with the same procedure, norton lapping stone, 600 sand paper, 800, 1000 and 2000.
while Im in the 8k, it feels smoooth....but in the 15k I heard like the razor on a wall....I hear the steel beeing removed from the razor, and see the darknes in the stone....
Is it normal? should I feel the shapton as smooth as the 8k norton?
I will test the razors maybe tomorrw
Regards,
You might need to round the edges of that hone. I get that sound when the edges of my stone are a little jagged.
Oh, and this is a recipe for a wired edge and the worst shave you can imagine outside shaving with broken glass or sea shells, trust me!

It's also possible that the Shapton cuts more. They are known to be fast cutters. You may wish to hone it on the Norton and just give it a few polishing strokes on the Shapton.
It sounds like you may be using too much pressure on the Shapton. I use the 15k Shapton and it's much much finer than the Norton 8k. It's nearly as fine as the chrome oxide. It does seem to be a fast cutter, mine turns dark very quickly if I use any pressure at all.
How many strokes are you using on either stone?

Maybe I need to round a little bit more the edges....I already did it, but I think I can do it more....Quote:

thanks all of you for your help
I didn't round the edges of mine, it never seemed to need it. It's very quiet when honing, though I don't remember how it compares with the N8K (I go from N8k to S8k, then any pyramiding is done between the S8K and S15K).
I wonder if maybe there's something embedded in your hone? Did you lap it on sandpaper or something that may have contaminated it?
I lapped it first with the norton lapping stone, then with 600, 1000 and 2000 sand wet/dry
Under the microscope I only see small part of metal and some black points.....maybe parts of the sand paper?
I think for most razors this would overhone the edge. Just MHO.Quote:

that's what it sounds like. You shouldn't get any long-term accumulation of metal if you rinse it off and rub it down with your hand under running water after each use. Once I start getting swarf sticking around between uses I lap my 8k and 15k shaptons against each other, which cleans them off and flattens them again.Quote:

I guess it has good quality because I didn't have any problem lapping the 8k Norton...
one more thing....
I don't soak the Shapton in water before each use, I only spread some water over the stone before using it ( I do it because the instructions from Shapton say that)

one question, without the use of the microscope I can see small porous regularly distributed in the stone...all over the stone....is this normal?
Some one has a Shapton 15k close photo to compare?
The pores don't sound right at all, mine is perfectly smooth and dense even under a microscope. You may be able to lap past it, but it's possible the stone is bad.
I don't soak either of my Shaptons either, I've heard some guys have had problems with that - the stone just isn't designed for saturation. I just run it under the tap for a few seconds, then refresh it with a spray bottle while I'm honing. When I'm finished I run it under the tap again and rub it with my palm to loosen the swarf.
One other thing that I've found is critical with the Shaptons is to make sure your blade is completely oil-free or the oil will penetrate the stone and it will start loading up with swarf and getting sticky and gritty. I run my razors under the hot tap water for a few minutes to wash off any oil before I start honing.
I guessed that...but I'm not too sure if my definition of pores is correct....Quote:

this is a picture of my Shapton 15k, the pen is for size reference.....
the pencil mark is to see the surface of the stone more clear, but I think the pic is clear enough to discover the pores of the stone....
I don't know if this is normal, or maybe a defective stone...

Wow, that's a big picture.
I just did the same pencil thing with my 15k and got similar results, so I think it's normal, or at least not unusual.
thanks a lot for doing this to your shapton.....now I know that the stone is fine....
I will lap it again and see what happens....
thanks a lot for your time and help
Parker...
one more question....
Do you see "pores" on the stone? Not just inside the pencil mark...the "pores" all over the shapton.....
Do you have the same kind of surface in your stone?
Thanks again
I'd say it looks pretty similar, but I don't see the "pores" you're talking about, neither on my stone or in your photographs.
he he he eh.....
That was the main reason of the picture....
I think my definition of "pores" is not accurate...
Thanks a lot for your time...have a great day...
