[QUOTE="Lil' Blue Rude, post: 178011, member: 4627"] I'm putting a picture of how I sharpened my new impeller and a picture of a used impeller that I had sharpened. The new impeller has only been sharpened on top of the blade.The red arrows show where I began and ended it. I normally try to go a little farther back then that to make it a very smooth slope. The second impeller was sharpenend on the bottom when I got it. I marked where I sharpened the top with red arrows. The green arrow shows where the lead edge is, in the picture it looks like the lead edge is higher but it starts where the green arrow is. Because the impeller had been sharpened on the bottom I would have had to remove to much material to sharpen it like the new impeller (the blue line shows this) so I blend the bottom end taking as little out as possible. That's the way I sharpen a new impeller and and how I fix a impeller that's only been sharpened on the bottom. [/QUOTE]
