my new Shapton 8K glass loaded up bad

Wed May 22, 2013 2:56 pm

I was sharpening a knife on my EP

I have the stock EP stones 120-200-400-600-1000

most cases i use the 600 to start

then i move to the shapton 8K then to the .25 micron strop


I'm confused as to what i did for my 8K to load up? it loaded up and scratched my nice polished edge (knife is is sharper then is needed lol)

i used my dimond plate i got from here to bring it back

Did you use a lot of pressure? That would do it. I spray my stones often too. My 8k loads a tad, but not much.

no more pressure than the other stones i use in fact on the 1000+ i really just use the weight of the stone.... maybe a tad more

Strange, I can only think that you worked it till it was too dry, then it will definitely load & will need to be lapped to restore - this will happen to most grits in the range - use plenty of water - the GS stones are not that dependent on slurry formation for decent abrading.

Seems the EP 1k jump to a 8k Glass is a bit much EVEN accounting for two different grit scales. Something inbetween would be nice. Even on the other end 8k to 64k (.25 micron) is a pretty big jump too.

But regarding the 8k glass - use more water and don't run it dry. While they aren't a soaker but a splash and go, do more 'splash'. Keeping it wetter will give you a shinier finish too as there will be less metal swarf in the mix. Glass stones will load up if run too dry as will most any other stone. Lap the surface down to clean and flat, use more water and you should be fine. Alternatively a drop of 2 micron CBN on the stone surface will reduce to eliminate metal swarf loading as the stone surface releases particles more rapidly.

Short answer - more water.

thanks

would you suggest the glass 4K for a step in the middle, I plan to add the 16K to my line up on the high end.

Thanks :)

Yes. The 4k is a good intermediate stone. Depending on use (steel type etc) you may also want to add a 2k later too. It is good to realize that the jump from 1k to 2k is double - just like the jump from 8k to 16k is double.

thanks to all in here for the advise, I now use a crap tone of water and a tissue to wipe the stone and pull out build up. and it work great looks like a mirror

I just ordered 320-500-1000-4000-and 16000 glass stone to add with my 8000 !!!

in fact i have even though about just submerging the hole thing......... LOL underwater sharpening...... but that wont work for high end handles or one that could get water logged

I like to keep one of the blue scotchbrite sponges wet and handy. It's super quick to wipe stone of swarf and wet it at the same time.
