Thread: DMT D8F for light lapping/stone cleaning work?

Hey guys,

here in Europe DMT´s are hard to come by.
They come either expensive or they do not at all.

The only DMT easyily available are 120, 600 and 1.2k, ie XXC, F and EF.
Prices are equal.

I have a system for lapping my stones with loose abrasive up to 400.
This leaves the stones completely flat but scratched. (yea, I´m picky)

What I am looking for is not a hole lapping solution,
but something quick to clean stones from debris
and refining freshly lapped stones like Naniwa.
Also the stone should fit in as bevel setter for str8 and especially kitchen knives, followed by a 1.000.

DMT f and EF come to mind, but I wonder if these would stick to the hone to be lapped badly.
Did anybody ever use DMT F or EF for light lapping/cleaning/refining?


Thanks

the finer MT tent so stick, but if you lap under running water you will not have as hard a time.Have you tried Atoma diamond plates, they are supposed to stick less and be better than DMt in performance.

I lap all of my stones with a 325 grit DMT, and that works great for me. This stone also doubles as a major edge repairer for razors with large chips or that require some serious bevel correction. I then move onto either 1/4/8/16k Shaptons or 1/3/8/12k Naniwas.

In terms of cleaning the hones, I just wipe them with a green backed sponge to get the swarf off them. Eventually they will clog/glaze though, and then I just give them a few laps on the 325 again.

1k is really a bevel setting stone, and you shouldnt need to drop below that unless there are things like chips in the edge that you want to remove. Starting at below 1k for every razor will wear away a lot of steel unneccessarily.

Some people here do use the 1200 grit DMT as a bevel setter, but I have the 1k Shapton and Naniwa stones that fill that gap very well.

You guys are quick!

I sharpen many different blades in any condition including some really messed up kitchen knives.
So far I have been using a polycristalline no-name diamond stone for this kind of work. Not very pleasing.

Atoma blades are even harder to find here. I am happy at least these three DMT are available...

I have been thinking about the 325 very much, too.
Unfortunately it is not an option, because no vendor in germany carries it
and I already have a basic lapping solution.

I will just think about the 600 for a while.
It seems to be a good way to clean my finer stones wich I do after every session.
I have to do so, because my wide beveled kitchen knives reaaaally clogg the stones.
They turn completely black after one session!

I was only wondering if the DMT Fine would stick too much to move it.
Maybe I will just give it a shot

If you are doing the lion's share of the lapping with something else you might get by with a higher grit plate for cleaning the swarf while honing and not ruining the plate. OTOH, you may wear the plate out quickly. Sham wore out a D8E 1200 using ir for a lapping plate.

Here is what Dia Sharp says on lapping waterstones;

Which grit is the best grit to use to flatten my Japanese water stones?

We recommend a DMT® coarse grit (45 micron, 325 mesh) or extra coarse (60micron, 220 mesh) 8" or 250 mm DuoSharp¨ bench stone for flattening Japanese water stones. It’s fast and easy. Make sure there is plenty of water to flood the surfaces of the stones when flattening to wash away the slurry made by the flattening process. View Color-coded Grit chart

Atoma,
can be purchased only from Japan as faras I know
a few sources;
Japanese Diamond whetstone #1200 grid for professional - eBay (item 250620327688 end time May-22-10 17:19:03 PDT)
I think it can ship SAL so no fee.

Tsuboman 'Atoma'. : Tools from Japan, Japanese woodworking tools direct from Japan.

those are same size but cheaper, I am not sure what is the difference, but you could ask.

Hope this helps.

Have you tried this German vendor? He seems to carry the 325 (pretty expensive though).

Same here. The XX 125 eats hones for breakfast and cries for more. It does leave deeper scratches though. The 325 takes care of those and between the two way less work.

Hi,

You can find DMT stones from Germany at Dick.

Just watch out when lapping or cleaning your hi grit hones with coarser stones that it is the right stone that gets lapped. Softer always takes the wear. There's some difference in softness between natural and synthetic stones.
I've been using wet/dry sandpaper (about 220 - 600 grits) glued on a sheet of glass to lap my hones. Works ok.
