Hi Clay,

Nice!!

Just a couple of questions:
(1) Are these images from your new metallographic microscope?
(2) What is the scale of the images (if you know)?
(3) Are these photos taken as black-and-white?

Looking forward to more of your results.

Sincerely,

One of the things that I found really interesting is that I still experienced rounding with stropping after lowering the angle by two degrees per side. I'll try the experiment again at 3 degrees lower per side and so on until I find the setting that allows me to just reach the edge without rounding.

Howdy

Just a couple of questions:
(1) Are these images from your new metallographic microscope?
These are from the new scope. The 100x objective still isn't working, so I'm limited to 800x.
(2) What is the scale of the images (if you know)?
What do you mean by scale? Are you talking about microns/pixel or something else? The camera is 10 MP.
(3) Are these photos taken as black-and-white?
These are taken in color.

So far, it's a really fun study to do. I'm working on a developing a little jig that will allow me to hold the blade in exactly the same place on the stage so I don't have to do so much fiddling for every picture.

Hi Clay,

By "scale" I just mean a length-scale. For example, what is the length across the width of the image? Or something like a little line in the image with a measure of how long it is (something like 0.01mm, or 10 microns, etc.). Maybe you could take an image of your linear stage micrometer at the same magnification?

I'm kind of curious how big the scratches are.
Sincerely,

No problem, I can do this.

Clay,
Just curious, what is the problem with the 100X objective? I have no experience with the kind of microscope that you have, but have spent lots of time with various lab microscopes. Usually changing an objective is relatively easy...
