I have some 6" jointer & 12" planer blades in need of sharpening. I also have access to a surface grinder at work. The last time I sharpened my jointer blades with the surface grinder, and a borrowed machinist vise. The guy who owns the vise no longer works there, so I was figuring that for the cost of sharpening multiple sets of blades, I might be able to buy something and do it myself. Anyone sharpen this way? Or any other suggestions for fixtures to buy for this machine? If I have the local sharpening company do it, the bill will come to around $82.
