After using my QT12 a few times now, It's evident that I'll need a pretty big bag of grit for stage 1.
I see the Rock Shed has 50lbs of 46/70 (which I've used), and KN has 35/70 in 45lb bags.
With shipping, the Rock Shed is almost $30 more than KN. Is there a noticeable between the two grits for a large barrel?
Thanks,

Because the 46/70 has a "smaller" size max grit particular there will (in theory at least) be more (denser) grit pieces. In practice we are not talking any measurable difference. I have never used the courser XX/70 grits as I bought a 50Lb bag of 60/90 10 years ago and have not used it all up yet (I have about 10 Lbs remaining) but the difference between the 2 will not make a difference (time wise). Go with whatever is cheaper (unless you have a reason to choose one over the other). I have used both companies grit with great success.

Also someone did a test, not sure if I saw it on here or on youtube, but I was surprised to see 45/70 performed worse than 60/90 for course grind. I think that was specifically in small barrels though, not having the falling force to break the grit; you might be okay in the QT12. This popped up when searching: "The Rock Shed sells good grit and so does Kingsley North. I bought 50 lbs of coarse grit from Kingsley North. Don't let the shipping cost scare you. If you ask them, they'll ship it in a large flat rate box ($18, I think)." forum.rocktumblinghobby.com/post/837209/threadThanks. Yeah I saw that when searching before posting but there wasn’t much discussion comparing the two grits. Looks like there isn’t too much difference being 35/70 vs. 46/70. This would be for a large barrel only. I use 60/90 in the 3lb barrels.

Johnson Brothers has 44 lbs of 46 grit for $99 with free shipping. It's one thing that they seem to get out very quickly. They have 20 kilo bags that they've pre-packaged in flat rate boxes. I ordered about 2 weeks ago (during Quartzite which can be really bad with JB) I had it in 2 days. The other time I ordered was similar.

Shipping at rock shed is always adjusted after the item actually ships and it has always gone down for me. If you are looking for an accurate price with shipping I would give them a call. Each time I order my 50 pounds of grit I always add rough rock to my order so I so not know the cost to ship just the grit.

My first order from them when I bought an assortment of grits, the shipping was adjusted. I forgot all about that.

Rock Shed ships in flat rate boxes. When I order rocks from them, I usually add a note saying "If there is room leftover in the box, stuff as much 60/90 in as you can and charge me the difference". I want to make as much use of the flat rate shipping as I can.

I use The Rock Shed for supplies even when the prices may be slightly higher because of the quick service and the expertise that Shawn will provide when help is needed when tumbling. Shawn has always been very helpful with any problems I have had and will guide buying decisions for projects.

Shawn has always been very helpful with any problems I have had and will guide buying decisions for projects. I ended up ordering from the Rock Shed anyway. They've been a great place for me in the past. It didn't sound like there was much difference in the grits, BUT, I have been using 46/70 for a month or so already with good results. In the long run, I didn't want to commit to a 45lb bag of 35/70 should some problem that arise with an unfamiliar grit. The tootsie rolls in the order pushed me over the edge! haha I'll try the Kingsley North 35/70 some other time in a smaller amount.

Please don't get me wrong as I use the Rock Shed all the time. My last two tumblers were purchased from there as well as 35 lbs of rock. I have also bought a bunch of rock and barrel lids from Kingsley North as well. Both have shipped quickly and have done very well by me. Of course I always get some candy from the Rock Shed, but being diabetic, this really only benefits the grand kids lol.

Went through it faster than expected as it breaks down very fast in 7 days. For those who have used the 35/70 from Kingsleynorth.com, what is your experience vs. the 46/70 silicone carbide? If it eats rocks in a week, I'll pass on buying it to replace 46/70. If there's a better source for 46/70 that doesn't turn to complete dust like 220 when I dump it at the end of a week, please chime in with some sources. I need some suggestions for the first extra coarse grind in a 12 lb lortone barrel. Tumbling mostly hard stones like quartz, quartzite, jasper and chalcedony types. Thank you in advance. Tumbling and dumping multiple barrels like a crazy woman during the warm summer months in Michigan when water is available in my shop.

I have been using 30 Grit Silicon Carbide for almost 5 years now in my Loretone QT66 dual 6 pound tumbler. Loving the aggressive action and the grit breaks down to smaller than 600 Grit in one weeks time. Wanting fast 1st stage grinding, I probably use a different Stage 1 method than anybody else. I will load the 6 pound barrel to more than 80% almost full of rocks, with a couple of large stones in there. Then add 1 inch of water in the bottom of the barrel, very little water, will need to move a few rocks out of the way to see the water level at the bottom. Then roll it for a week. To me, this is the fastest grinding/Rounding that can be done in a 6 pound barrel. Frequently the slurry will be rather thick like pudding, but has never been a problem for me. My last grit order from Kingsley North was for a 50 pound box of 30 Grit.
Roll On . . .

My new tumbler has three 12lb barrels and two 6lb barrels. Needless to say, after a couple weeks I can see that my 46/70 from January is going fast. I’m starting to explore the new grit options again. I’m glad to read others experiences above.

I only have a double 3 pounder but think I’ll try something similar to your method on some local rocks that need a lot of grinding down. Many thanks!

I’m with wooferhound, I use 36 grit in my six pounders. Some slurry and not a lot of water. At the end of a week, no noticeable sign of grit, fast grinding for sure. I don’t do many small stones, mostly big stuff, works for me.
