Mr. Rupert, Thanks for the additional explaniation. Appreciated!
"The EXL wheels are 3M products and an are entirely different product."
Hmmm... OK. I can intuitively imagine how a Scotch Brite like material would be good at deburring. That's why I tried a Scotch Brite belt in the first place. If those wheels are something different, I'll look into it. My testing with Scotch Brite extra fine belts was not encouraging.
What I have found is that removing the first bit of burr is not that difficult. It's that last bit if remaining burr that is wider at the base just above the edge is what is difficult to remove. I was never able to remove that with a cotton buffing wheel. Maybe the one you reference is significantly different from what I have. That's always a possibility.
Also, please understand that when I say something didn't work for me, that does not mean it does not work! I'm just sharing the results my own testing. For things like deburring, I'll try something, check it under the microscope, test for sharpness and repeat, etc. While I try to be careful enough to at least conduct a test that will result in informative results, it is by no means conclusive and/or definitive. It's just what I've seen in some particular tests.
I have seen blades with remaining burr that test as very sharp. What I think happens is that the burr itself has been sharpened and is very straight out from the edge. Even though it can test as very sharp, shave hair and cut paper, etc., because I can actually see remaining burr I assume that edge won't hold up very long. I have even seen times when after that burr is finally removed, the edge will test as slightly not as sharp. But that is actually a good thing because what remains is the actual edge that will endure, and not just sharpened burr material.
A lot of you guys have sharpened far more blades for many more years than I have. I would be perfectly happy to one day find out that everything I know is wrong!
I really appreciate any and all feedback and info. I just want to learn, so I welcome and am thankful for any and all ideas and information!
