we will try it on sunday with the scope. I am not a betting man, but would bet a bright shiny new quarter that that burr will still be there. it will be very fine according to the stone being used, and centered with each stroke, which is why you cant feel it with your fingers, but it will still be there.

take a look at the very nice drawing of a burr earlier in the thread, if you abrade one side of a chunk of steel at the same angle to where it meets the other side, the very next stroke should cause a burr as the steel at the very edge is too weak to hold on to the body of the chunk of steel. in my video, we can see this at 6000 grit. im betting that we can see it with that lense at higher grits, and still more with the other lense.


ill bring the gopro and we can record what we see.
