So, with our big wild game processing day coming up in about a month, it's time to sharpen grinder plates and knives. Since we will be doing 24 deer and 3 wild hogs this year, we will have two grinders going. So I picked up Dad's grinder today and looking at the plates and knives, yep-time for a sharpening and honing to get back into shape. I do not know the last time these were done...they were in pretty bad shape.
I had started with 150grit, but had to go to 80 grit to take a lot of metal off the face of the plate because of the deep grooves. Then worked it over with 150, then 400, and finally 1000grit.
That is more like it!
Also-I ran across an old post by daveomak suggesting to use a ceramic tile for the lapping surface for the sandpaper...that worked beautifully!
