Ok I've got an old Wostenholm that I'm having some problems with. I just got a new norton 4k 8k and I really like the abrasiveness to it. I don't have a flattening stone and I can't afford to buy one right now. I have marked the stones and used an old very abrasive stone to take the initial grit out of it and I am able to get the razor pocket knife sharp but I can't get the bevel set. I have tried the circle progression a few times on the 4k side and though I get a good edge the bevel is definitely off and I know its because I can't get the stone flat. So my question is is there any other way I can get it flat? I know using sandpaper isn't a good idea because of the grit coming out. Am I stuck until I can afford to buy a Lapping stone or is there any other way around it just for a temporary solution?
