Thread: usb microscope

I have the same microscope and find it invaluble for setting a bevel. I usually just hold it with my hand. All I need to see is if the bevel is set.

Having said that, your set-up looks fantastic.

latest pics. this is one of my vintage razors, by hartford cutlery, after 1 shave. bad chipping going on. the honing was: king 1000 grit, diamond 8000 grit, jasper, chrome oxide on maple, bare leather. what’s going on here?

Did you inspect the edge at each honing stage to know it is a post shave problem. I think the 8k diamond is likely the culprit . Altho it is 8k the scratches cut deep & deep scratches can chip out. Previous pitting may also have weakened the steel.

I did inspect at each stage. the jasper cuts slow, so it's possible that I didn't get to the bottom of the 8000 scratches before going to chrome oxide. next honing I'll substitute .5 micron diamond for the jasper, then chrome oxide. these are down near the limit of my scope to see- the chrome oxide just makes it shinier as far as the scope can resolve. I think that the scratches below about 1 micron are sub-pixel wide so I can't see them.

previous pitting is a definite possibility with a vintage blade.

Thank you for the post. Your 200x gives a nice image. I am using a spencer stereoscope that only goes to 30 power, but the image has good resolution. It's interesting how the pits run like sand on the beach when they're stropped with a little paste.

I am beginning to collect vintage razors, and some of them have pits like yours on the threshold where the bevel begins. They hone out fine but its interesting the effect of the various sharpening techniques are.

the edges on the vintage blades look bad but shave surprisingly well. I haven't had them long and both are junkshop finds, so it might take a few honings to get through to a good edge. they look great to the naked eye. the microscope will be a good aid to achieving a better edge

Nice pics Bridger but try to get some info on what razor and what stones tagged to them.

it's there in the image file name.I guess tumble doesn't display them. you're right, I need better tags.

How far away is the lenz from the blade edge?

I can only get decent images with the lenz on the edge. What setting on the software are you using?

Can you post a pic of razor being photographed?

Thanks for the images and thread.
