Nice and simple way to sharpen up your mincer plates and knives.
Works a treat.

Excellent, been thinking about that recently. Thanks for the share.

Years ago I salvaged a porthole from the bottom of the harbour underneath the Shelly Bay hangers. An inch thick piece of very strong glass. That's been my go-to for lapping stuff. Just get hold of a variety of grits of wet and dry and away you go.

Some of the very large, and a lot of the very cheap mincer plates are only case hardened, so don't be too disappointed if they don't work once you are through the hard layer - they were buggered at that point anyway.

That system doesn't really work once a plate gets well worn, What happens is the working side if each hole in the plate rounds off, so to sharpen that plate you would need to remove a significant amount of material to remove the rounding in that working edge, not really practical using the system as shown. Once that rounding occurs the motor works a lot harder and the meat is not clean cut, it is mashed. With good quality plates it takes many a few hundred Kgs of meat to wear the plates, so it shouldn't hurt too much to bite the bullet and buy a new one. Ross is correct in what he says above. Also the cheaper plates are not precision ground so the holes are not sharp to begin with.

This just what I need. Thanks McNotty

In theory same technique will work with your hair trimmers too.

Got me thinking MD. Unsure if would work on hair clippers or not. I know grinding plants for shearing gear have an “included angle” to get the grind right.

I've seen shearing gear done in linisher....but that $60 pair of no brand clippers sitting in drawer might just come back to cut not pull hair again.watching clip I now understand why couldn't get it right with oil stone lol
