What are the directions for using metal Universal grinder inserts and how to decide which one to use?
Like the one on the right in this picture. I use the one that has the least “spokes” and that is hard enough to push meat or food through. What do you use the inserts with more “spokes” for?

I was hoping someone who used one could give me ideas.

Finer grind.
It’s an extrusion process and the forces are primarily mechanical and hydraulic.
dont grind it
It depends how fine you want to grind the meat. First you start with the largest wheel then go to the next size down and so on, until you are satisfied with the grind.
