Any good tricks for this final operation? Knife is clean, ground and then!!!!final bevel to screw up the works. Should edge be up as in normal grinding?
 
I do the secondary edges first in case I screw up I can bring them back into alignment with the main edge. either hollow or flat grinding, hit your false edge first.
 
Grind edge down!!! :eek: I usually tape the blade, all but the area I'm sharpening. Estimate the edge angle by the distance between the spine and platen, keep this distance the same for both sides. I start at 220 grit, make two or three passes per side until I start to get the wire edge, then even everything out one pass per side until it's right. Depending on the use for the knife I may go to 400 or even 600, then take the wire edge off with a couple of light passes on the buffer. Then I shave a patch of hair off my arm to make me feel good. ;) Hope this helps some,
 
I grind the blade as close to a cutting edge as possible without being to thin before heat treat. I put convex edges on all my knives sharpening on a 2x48 grinder horizonally. It's pretty tough to mess up sharpening the secondary bevel this way.

I cut the edge using a portion of the slack belt about 2 inches above the small wheel. edge down starting with 220 then to micron. Sorry about the mixed up answer before Thinking about something else Blond moment :D :cool:
