Thread: Coticule edges (dilucot) under microscope 160x

Hi Alex,

My magnification equipment is all except scientific

I am using a children’s experimental microscope at 160x magnification (10x objective and 16x eye-piece).

I am taking pictures with my cell phone hand held through the eye piece. This setup produces some optical issues like spherical aberrations (getting blurr towards the sides of the picture) and chromatic aberrations (yellow-blue lines along the contrast edged) wich are not easy to come around. But in their center the pictures are quite useable.

For illumination I am using an LED desk light turning its head in a way to get side light. Before taking a picture I turn the razor to get maximum light reflection from the scratches.

I put the razor on a magnetic self made wedge-holder.

Here are some pics.

Alex,

Yes, I am was using my exceptionally fast and fine nakayama kiita I got from a friend of mine (on its back there is a number #726 ;-)).

I haven’t gained much experience on that stone yet but as of now it can produce for me HHT4 edges finished on milky tomo slurry.

Refreshing was done without tape. Nakayama can easily remove the unicot-second-bevel produced with taped spine before.

Yes I am aware of the micro-beveling effect of the slurry. I was hoping that when finishing with tape the higher angle (caused by applying tape) can compensate any microbevel from the nakayama-tomo-slurry. This for me was kind of proven by the fact of getting higher HHT results of the unicot finishing on Coticule.

As per synthetic finisher for refreshing: you’re absolutely right, this would definitely help in terms of consistency, repeatability of the tests as well as it would allow others to reproduce them.
But I have never used high grid synthetic and currently not planning to do so. I am a fan of natural hones, to me putting of a blade to a piece of natural rock has something magical to it. I love how they feel to my hands, love the earthy smell and the uniqueness of the each and any stone.

As they say 'Many roads lead to Rome' you found a nice one! Good job!
I can totaly relate to the natural stone fascination, they are sweet once you figure them out.
