I recently bought a used QT66 and I am wondering how full of rocks it should run. I am used to the 3 lb Lortone barrels which I fill 2/3 full as instructed by Lortone (except for Polish where I have been filling it fuller than recommended with better results).
Is it 2/3 full for the 6 lb barrels too? How do you judge how full it is when the barrels are so wide and short? If there is a manual online a link to it would be great! Also of course any advice based on your experience!
I am looking forward to that 6 inch drop action in Coarse!

The owners manual for the QT66 suggest that you feel it 2/3 full. I just eye what I think is around 2/3 full but if you want to measure you would fill the barrel with just over 2 1/2 inches full of rock.

The guy who sold it to me was relocating out of state for work and I got the impression it was a bit of a rush. The barrels were full or rocks and unbroken down grit. I maybe should have left them as is, but I was curious to see the rocks. He had it filled up more like 1/3 to 1/2 so I added more rocks. It is amazing how much 12 lbs is when you are use to 3.

It will make a big difference in your productivity. More volume, faster grind.

I just eyeball my barrels when filling them. However, I also have a short piece of PVC pipe that I cut to help me measure. Measure the barrel from the inside bottom to the bottom of the lip that the lid rests on. In other words, depth of the inside of the barrel when the lid is on. Divide that number by three to find one third the height. Then add on the height of the lip of the barrel. Cut a piece of PVC pipe (mine is about four inch diameter) to the length you calculated. You can use this to set on top of the rocks in the barrel to see when it's 2/3 full. The pipe should be about level with the very top of the barrel when it has been properly filled. You don't have to use PVC pipe, you can make your measuring tool out of a chunk of wood too. After you measure for a while, you'll get used to judging without measuring.

Measuring from the top instead of the bottom is a good idea. Obvious, but I never thought of it! It will be great to do more rocks. My club gives free rocks and grit to people who tumble rocks for the kids' grab bags at the annual show. You keep half and you donate half of the finished rocks. It was danged embarrassing to only be able to donate enough for about 3 kids!
