Burr removal is more difficult, and in my mind, just as if not more important than the actual sharpening.
Of course, I could be laboring under a delusion, but I have not seen that a buffing wheel can completely remove burr. I've tested it a number of times with both sharpness testing and microscopy. It did not pan out. There was always burr remaining.
Concerning Scotch Brite duburring: As I mentioned before I've found it to dull an edge so I want to make sure I'm understanding you correctly. Are you saying that you use the Scotch Brite wheel to deburr the edge right after sharpening?
What do you mean by "use instead a 3M EXL 8 inch wheel to blend with" ? What do you mean by "blending"?
Sorry for being a bit slow!
We both agree on burr removal importance. Try the untreated loose buff it works for me (Woodcraft). Use the buffed edge for cutting paper or etc and rebuff until you get the results desired. DO NOT over buff do not over buff - I am not talking about rounding the edge over. When (sharpening) the "apex" is created - LIGHTEN up, lighten up. Once you have sharpened both bevels, and they shake hands STOP sharpening and begin burr removal if any burr remains (very light touch one or two passes).
In ref to the remaining burr if any is remaining often sharpeners chase said burrs with a progression of finer grits (I do not). We need to be very careful and let the sharpened bevels shake hands before we start burr removal. Again I often use a Scotch Brite belt to de burr, anything will usually work a MDF wheel, EXL wheel, cross grain (end grain), a polished steel - anything will work. Again the stated Woodcraft buffing wheel is my favorite. WOW! what an edge. If the two sharpened edges shake hands we will always end up with very little de burring and a very sharp blade.
Yes! I use a Scotch Brite belt to de burr with (blending). Use the Scoth Brite WHEEL to remove rust, dried blood, guts and etc.
The EXL wheels are 3M products and an are entirely different product.
Blending for me is the transition between a properly sharpened edge and on to the final burr removal if any remains (cotton buff).
You are not slow I am not the writer that you and Ken are.
We need Thomas (EdgePal) to enter this conversation.
