Carbide scraper blade

[Wannabewoodworker]

So after reading one of the threads regarding carbide sharpening with my T7 I told the boss I had the machine and i would be happy to sharpen his carbide scraper blade. Well contrary to what has been posted here the Sg-250 stone has little to NO affect on a carbide scraper blade. I was after a very long time able to get some of the blade polished shiny like a mirror but actually sharpening it back to factory new was an abyssmal failure. Who here has been successful sharpening carbide tools with this system??? Is this even possible??? I know Jeff had stated in another thread that it can sharpen carbide but I am here to tell you mine would not sharpen carbide. I even graded the stone time and time again to try and get the stone to cut the blade but to no avail.

If I have posted anywhere at any time that the SG-250 would sharpen carbide, I would certainly like to know where, because it needs to be deleted.  I have never to my knowledge written that.

The SB-250 can touch-up but not reshape carbide.  The SG-250 will have no effect on carbide whatsoever.

Jeff,
       My sincere apologies if I miss read your reply's concerning sharpening carbide tools. I know you said the T7 could sharpen them I just did not realize you were referring to a different stone than the one that came with my machine. I will have to look at the SB-250 and see if that will do what I need to do. Thanks for the response as always.
