I have HSS 12" planer blades and 6" jointer blades (Hitachi). Are these
something I can sharpen myself? I was going to take to local sharpening but
they are closed on weekends. I have stones and I looked for jigs or
something meant to hold the blade properly and could only find a $250
sharpending motorized wheel w/jig). Any URL reference or opinion is
appreciated.

thank you
