Tried to sharpen my plug cutters (fluted, snug plug style) today for the first time following Leonard Lee's techniques described in his book (Complete Guide to Sharpening).
I think it went well, but I tried to sharpen the tops of the flutes and I had difficulty maintaining the bevel angle by hand. I did ok on three of the four flutes, but the forth ended up multi-faceted. I tried it and it seems to still work ok.
Any advice? Insights?
