Small Engines (Lawn Mowers, etc.): Sharpen REEL Mowers, angle grinder, dremmel

Question
Is there a way to use a "Dremmel" or an angle grinder to sharpen a reel mower? Does anyone make a tool to get the angle correct? thank You.

Answer
Golf courses sometimes use reel sharpeners that bolt on their equipment.  I'm not sure how they work because we rarely service their equipment.

Don't know about the Dremmel...never tried.  We have a special reel grinder we use to sharpen the blades; it keeps the correct angle and ensures the height is the same on all blades.  
Have you tried any other message boards?
