We all know there is such a thing as too little grit to grind. BUT.... Is there such a thing as too MUCH grit to grind? Is there a Point, when you have so much grit in the water, that it basically "Becomes cushion" and ceases to grind the rocks? This is fun thought exercise/ Video Idea for Jugglerguy . What do yall think? I am talking so much grit that it is JUST fluid, Like wet slightly overly wet sand, when it will run through your fingers but just barely. I would Love to see Rob do a Video on this where he loads a 3lb barrel with rocks, and like 1 1/2 to 2 cups of grit, Just to see what happens!

I wonder if your the first person to ponder this question. From what I've read what happens is exactly what you stated, it "becomes a cushion", no grinding action, the rocks just slide off one another, however, I'm thinking that after weeks and weeks left alone it should start breaking down, but that slurry would be super thick and nothing would happen. With 1 1/2 cups of grit in a 3#er, I think it would turn to cement.

I would like to do a video testing how grit quantity affects tumbling, but two cups in a small barrel seems like it's going way too fat. I'd rather keep it to quantities that might actually be used in actual real life tumbling. For a three pound barrel, maybe 1.5 tablespoons, 3 tablespoons, and 6 tablespoons.

Ok ya that is a bit of much, but like 1/2 cup reaslistically in a 3lb barrel is only slightly more than 6 tablespoons which is 0.375 of a cup so not all that much less than 0.50 of a cup.

Yes, half of a cup is much more reasonable.
