Calculation seems off.
Porosity, Benjamin.

Bet that is the case snuffy. Just plain smart to sell LFRB/MFRB's in any product. 45 fits fine, no fuss, all are happy. Price is mighty fine indiana. Probably send it from Washington Mills at Niagara Falls NY by barge to Kingsley at Norway MI via barge across L. Erie and L. Huron. Cheap freight GFRB (giant flat rate barge).

Ok, Kingsley replied about my inquiry about shipping costs of 50 pounds of 30 grit and 46/70...they responded that either would fit into a LFRB and cost would be $16-$18.

Bulk density (one cu ft) of various abrasives. LFRB is 12 X 12 X 6 = half cu ft Note garnet Silicon carbide 106/cu ft pounds of blasting grit. Void volume 115-106 = 9 pounds. The Chart below shows the "Bulk Density" (Weight per Cubic Foot) of several common Blast Cleaning Abrasives. Silica Sand 100 Nut Shells 45 Mineral Sands 127 Corn Cobs 35 to 42 Flint 80 Aluminum Oxide 120 Garnet 147 Silicon Carbide 106 Coal Slag 85 Steel Shot/Grit 250 Copper Slag 112 Glass Shot 100 Nickel Slag 85 Plastic Grit 45 to 48 Sodium Bicarbonate 61 Ferric Oxide 172 www.manusabrasive.com/bulk-density-chart/

Seems like the final charge was $88 + $18 = $106. Way cheaper than any SiC 30 I ever bought. As Ed mentioned, a bullet proof plastic bag. Some distributors charge some kind of hazardous material charge. Well, that is probably the reason Kingsley may not post the LFRB offering on their website. Same billing arrangement for 50 pounds of SiC 80 if memory serves. Posted this back in October, funny it came to surface recently. They are advertising some 45 pounders as being shipped in a LFRB. I never thought to ask if they could cram the extra 5lbs in one. Still a very low $ per lb cost with the $28 shipping. Holy moley, look at this 80 grit price: The weights that they have posted is for a flat rate box full. I have mail ordered most of the grits shown and that was all that was fitting in the box

No shipping to boot. they must have bought a serious load of 80 grit. The generators at Niagara Falls is one of the world's largest power generators. Washington Mills buys their cheap power to make their abrasives. Certain you bought their SiC.

I also opened a wholesale account, so got it even cheaper. With that being said.... I should pull it out of my truck now lol

I should pull it out of my truck now lol Washington Mills salesman used to stop by and trade grit samples for rocks for his son's tumbler as I lived just off his route. Hard to find an abrasives expert. Learned a lot from him. Spoke of process to make abrasives. 'Samples', in 10 pound cardboard tube containers. Nice handouts, last us tumblers a long time. #4 #8 #16 SiC, freaky big SiC. Broad assortment of weird aluminum oxides. Mostly coarse to 600 grits. Have not seen him in a long time.

jamesp that would be a nice perk. I would exchange rocks for grit. Lol. Not to shield about the 4,6 grit. Might have to take a hammer to it to use it. Lol

Lol He was quite clear about the effectiveness of 30 to 46 silicon carbide particles being the most mechanically resilient size to hold up to cutting hard materials like agate in tumbler. Namely the shape, that the sifting operation yielded rounder more effective particles. That the flatter particles were separated sent on to further crushing for finer grits. And larger than 30 grit broke down inefficiently at cleavage planes into flatter less efficient cutters in a tumbler operation. Discussions with him primarily related to the roughing operation. The shaping operation takes so long, best to focus on it. Finishing relatively short operation.

That's interesting, this evening I'm doing a weekly check on a load that has been running the new 46/70 I got from Kingsley. Curious to see if it seems to be shaping faster.

Guessing you will be happy indiana. I tumble a lot of coral over and over, always similar and very hard. SiC 80 is really slow to shape it. Have run 80 and 60/90 in past for a long time, switched to 46 and saw marked improvement. So moved to the 30. Please post results.

The generators at Niagara Falls is one of the world's largest power generators. This doesn't sound right. Compared to the Columbia river, I don't think Niagara even registers. So I did a quick check and it looks like the capacity of Niagara generators is about 2.5 MW, and it looks like Bonneville Dam generators capacity is about 1242 MW Maybe I am missing something?

Grand Coulee #1 in US at 6809 MW, Niagara #4 in US at 2525 MW. I too might be missing something. en.wikipedia.org/wiki/List_of_largest_hydroelectric_power_stations

Niagara Power Plant www.nypa.gov/facilities/niagara.htm"You know it as one of the great natural wonders of the world. But did you know that the power behind Niagara Falls also helps generate some of the least expensive electricity anywhere?Photo of Niagara Power Project The United States and Canada have shared the Niagara River's water power—along with a commitment to preserve the beauty of the Falls—for nearly half a century. And our Niagara Power Plant will continue to produce steady supplies of clean, carbon-free hydroelectricity for another 50 years with a new federal license which took effect September 1, 2007. When the Niagara plant produced its first power in 1961, it was the largest hydropower facility in the Western world at the time." panamark, I think Niagara was the big player when Washington Mills built their production facility.
