Sharpening meat grinder blade?

old_goat2 · January 29, 2020, 09:06:47 PM

I've had my grinder for a while, never sharpened the blade before, looks like it's just a flat grind on all four blades. Am I correct? Could touch it up on a diamond hone I would think. Anybody know?

No clue but I'm in for the answer . . .

i wouldn't sharpen each blade individually but rather all at once on a flat stone or even a sheet of sandpaper on a piece of glass. that will ensure all the cutting surfaces are flat and on the same plane.

Yeah, that's what I did, don't know if I did it enough, but I have some large diamond stones and just spun it on them in the direction it normally turns. Ground 14lbs of moose and pork to make some sausage and it seemed to work good! I'll give Tom Clum a call tomorrow maybe and see what he says

You can flat sharpen on a stone or abrasive paper,I sharpened many of them on a surface grinder for people .

This is how I sharpen mine. It works very well and maintains a good flat surface. I use the pane of glass with wet or dry sandpaper.

I would second the pane of glass. I use this method to sharpen my plane blades and chisels. I have strips of wet/dry sandpaper glued to glass with double sided tape.

Don't forget the "cutting plate" that the blade cuts across. If that is also worn/warped it should be replaced. Tom.

I do hit the edge with ceramic sticks. I finish out the flat part with 1500 grit wet dry paper. I hit the plate with coarser paper and work my way up to 1500 to take any grooves out of it.
