Hey 'Hounds 'n' Rollers,
I've picked up several bags of grit because retail prices for smaller quantities are crazy and I'm cheep.
My thought is to offer smaller quantities of grit to forum members at what it cost me plus shipping and any materials. This is a not commercial endeavor in any way - just getting less expensive grit for myself and anyone here who is interested. Won't be interesting to large-scale or commercial tumblers, but might be worth it for hobbyists like myself.
My thought is SFRB's, but I'm open to any configuration.
Here's what I paid for grits:
SiC 46/70 $1.70/lb
SiC 80 $1.31/lb
SiC 120/220 $2.00/lb
SiC 500 $2.68/lb
White Aluminum Oxide 1200 $3.00/lb
Payment would be via PayPal only. If you're interested in any of these shoot me a pm letting me know how much and I'll let you know an itemized total including shipping, etc.
Of course for anyone who is close enough to Fallon, NV that a meet-up/hand-off could be arranged, no shipping costs would be necessary. I'll be road-tripping a fair amount in the region this summer, so something might be arrangeable at halfway points.
Please be patient for responses as it will be about a week before I'm home.
Argh

As an afterthought: I'm currently in the Portland, OR area and will be heading through Prineville/Madras/Mcdermitt/Winnemucca on the way home, so anywhere could also set up hamdoff within reasonable distance of that route. (I have all but the SiC 46/70 with me.)

I could use 5 lbs. 46/70 (am newbie, am assuming 46/70 would work about as well as 60/90
on mohs 8.5 material), 10 lbs. 120/220, 3 lbs. 500, and 5 lbs. 1200.
If there is a 20-lb. max. weight for usps, then I would wait and get the 500 grit later.
Is the "quick reply" a pm?
also, can newbies post in the buy/sell section?
I need to buy like 5 non-working mini-sonic vibrational tumblers.
Many thanks,
Mike

Hi Ampeg, welcome to RTH. I can't speak to the buy/sell question, but I don't believe a quick reply is the same as PM. The only way I've ever sent a PM is to select "Messages" from the menu bar at the top of the screen when I log in. It brings up a new screen that is pretty intuitive - just start filling in the blanks. Good luck!

Thanks, kskid----you're absolutely right about "Message" in the menu bar------I hadn't even noticed
it.
It looks like you've got to have 100 posts to be able to post in the buy/sell, so it'll be a while
before I can do that.

I need to buy like 5 non-working mini-sonic vibrational tumblers. Many thanks, Mike You may want to rethink your numbers a bit. I don't want to derail this thread too much, but I'll offer a few pointers... First, as to 46/70, what size tumbler is this going in? If you're not using at least a 6lb rotary barrel, don't bother with 46/70. Smaller barrels don't have the material weight to efficiently break it down. If you have small barrels, 60/90 is fine. Note: this has simply been information that was passed to me; I have not done any testing. As to amounts, you're awfully "light" when it comes to a coarse grit. If you're doing weekly cleanouts and are shaping your rocks for weeks, if not months, 5 pounds of coarse won't hardly last at all. Again, tumbler size is a deciding factor, but figure around 1.5 tbsp of grit per pound of barrel capacity. For comparison sake, I buy 50 lbs of coarse grit at a time, and only 5-10 lbs of the other sizes when I need them. Of all the sizes that you have listed in your post, are you aware you have not accounted for polish? Maybe you realize it, but 1200 is not a polish. It would be considered a pre-polish. Polish sizes are usually around 1:14,000 (1 micron). As to USPS weight limits, I believe any flat rate box (priority mail) can ship up to 70 lbs. I don't want to take away from the thread, but those are just some high points. If you have additional questions, I'd suggest going to the Rock Tumbling area and starting a new thread with your questions. Tell us what your plans are, what equipment you have, and you'll get pointed in the right direction. Better to be well informed before you jump into this instead of trying to correct things after the fact. Good luck. |

Hi all,
All of the grits listed in the original post are still available. I bought much more than I will need in the next 5 years (except for the 46/70 and 80) and I've only made any "pitch" here. Again, not trying to make money, just wanted lower price per pound and thought some hobbyists might be interested in same.
There's just one tiny hitch: When I left to come home, my car was loaded with other stuff and I left about 100 lbs of grit sitting on my dad's shop floor! I'll be headed back up there in the next couple weeks, so if you're patient, I'll still get it to you.
My signature is particularly appropriate,
Argh

I need to buy like 5 non-working mini-sonic vibrational tumblers. Many thanks, Mike Hey Mike, I'm no expert but based on my experience I completely agree with aDave on the 46/70. I have two double-barrel tumblers, one with 6lb barrels and one with 3lb barrels. If you pay attention to loading, the 6pounders just eat grit and extremely hard, extremely rough agate. (Buttery smooth slurry in 5 days with 1-1.25 tbsp/lb.) But the 46/70 is actually pretty ineffective in the 3pounders. 60/90 or 80 works better, especially if you don't load too full. Please see my other post about the grit shipping. (Facepalm) Argh |

aDave, thanks for the heads-up!
I've got a 3lb. used Thumler Rotary tumbler, and a Geosonics Mini-Sonic MT4 4lb. vibratory.
Actually, I thought the 1200 grit was polish, so it is a good thing you commented on that.
I'll have to look up 1 micron 14,000 grit, and the sieve mesh equivalent, so that I can grasp how
finely ground it is--------I imagine a dust mask would be in order when handling abrasive
that is that fine.

I'd love to get some grit, if you are willing to ship 10 lb of each from 80 to polish to Canada via USPS. Grit in Canada is expensive, so this would be doing me a big favor. Greig

Greig Hey Greig, Shoot me a pm and we can talk. Most people wouldn't consider 1200 aluminum oxide to be polish, and if what you're tumbling is anything like what I'm tumbling, you'll probably use at least 4 times as much 80 grit as anything else. At any rate, I go through 46/70 like crazy. |

Grit still available. Since it's heavy, flat rate boxes seem to be the most cost effective route.
Just to get an idea:
Small flat rate boxes hold up to 4.5 or 4.75 lbs of one grit, a bit less if there are several.
I just sent a medium flat rate box this morning. I reinforced the sides with some very thin wood from a crate, and was able to get 15 lbs of 80grit, and 4 lbs each of 120/220, 500, and 1200 ao.
I'm doing this as a zero-profit because it can help folks (including me!) reduce hobby costs.
Buyer pays what I pay for the grit, plus shipping, plus paypal fees plus a paltry sum for what a few ziplocks cost me.
All my grit comes from Abrasive Armory. Prices are reasonable, Paul is easy to deal with, and I can pick it up when I'm in the area 3-4 times a year so I don't pay shipping when I buy it.
He does not currently carry a polish. If there's enough interest I'd be more than happy to ask him if it's something he's interested in carrying, but at my current rate of usage 55lb of polish would outlast me.

Thanks for doing this! I would be interested in a SFRB of 400 grit next time around if he has it?
I run strictly 400 on my little flat lap that I use for the backside of cabochons - 400 does the trick on getting scratches and sawmarks out and staging it for a light shine on the wheels. I thought several times about buying some of your 500 for testing but 400 is working so good I hate to fuss with it again.
