How much grit do you use? I put 1 T coarse grit in my first batch of rocks and it ate through the plastic barrel. Did I use too much??

I used the 3 bags of 3 different course grit that came with the tumbler. The course compound turned for 5 continuous weeks. Medium grit for 8 days, and polishing grit for 10 days. There is wear in the interior of the plastic drum, but no more then I expected. Next batch, I'll use two extra grades of polish. The rocks came out smooth but not as polished/shiny as I expected. Purchased for the rocks our granddaughter "mined" at a hunted Halloween mine. We made necklaces and key chains for her to give as Xmas presents. For more serious crafting/jewelry, I'd recommend a more professional tumbler.

Sanding disks come in different grits, even 60 and 40 and they take of a lot of material quickly. I have used 150 grit...not sure if you can buy 240???...wear some gloves or attach the guard (if possible because these grinding/sanding wheels are aggressive and will take a slice from your hand if you do not respect it. Also try to use a rubber washer, it flexes while supporting the cardboard sanding/grinding disc. PS there is not such thing as a stupid question!!!!

I would think water is fine. The idea is removing grit, not pasting it in. Water also cools down the process.

You tighten / loosen a screw to adjust your grind. I keep an eye on the ground material and adjust the screw if needed as I go. As mentioned in other reviews, multiple grindings may be needed for your desired texture.

I have 2 if them and I finish sand at 180 grit and 220 grit. I do not have swirl marks in hard wood. Sometimes pine will swirl a small amount. Then I hand sand and it come out.

Hi - I'm not a grit expert, but these look pretty coarse to me. Hope this helps.

Do NOT soak the 6000# grit (white) stone. Everything I have read states that because of the fitness of the grit, the can become fragile and crack. Soak only the lower grit (brownish) stones. see Korin website.

I really don't know exactly. However, if the stone is an oilstone, and I believe it is, then its probably 240 grit for "medium" and 280 grit for "fine". There doesn't seem to be a specific grit noted on the stones or packaging for oilstones, and just using "fine" or "medium" terms to describe the abrasiveness seems to be the norm. However you can get more info if you search the web for woodworking, sharpening etc.

I I would say around 1 1/2 inch diameter. Also I have observed that the rocks only need a couple days tumbling after the first grit. (7 days required on the course grit). Good luck

I emailed Winco and all they said was "The grain is a Fine/Medium grain" so I guess we're on our own. I'm looking to get it for major blade repair as well as leveling my higher grit stones (1000-6000 grit). Good luck.

Grit and size are what is important. Almost any brand is good anymore. Some, though, works better wet with water and some is better dry. For wood I'd say dry is best.

Its a good idea to separate some of them obsidian was in mine and they just disappear if tumbled with quartz. They give you enough rocks for around 1 batch but some of them will come out poorly if all tumbled together.

I have had the same problem. We used fine at first and recently I changed it to coarse. It still has a little sediment but seems to be working better.

I use the 120 and 240 grit. Remember the higher the grit number the smoother the nail will be and the less likely it will split and crack.

That sounds like a really BAD idea. First of all, if your bores are so dirty that you felt inclined to put a power tool in them they must be really bad. Second, copper lead and brass are very soft metals, but I wouldn't put any other metals at high speed through my barrels.

From 4 to 6 weeks. Some polish faster, others take longer. During each stage of polishing we go through each barrel after a 4-5 day period and select which rocks stay back in the barrel they came out of and which go on to the finer grit for polishing. If you take your time you can get some very beautiful rocks. We use two of the two barrel polishes so we have all 4 grades of grit going at once. Just keep moving them to the next level of polishing. After 5 weeks you should have a polished barrel of rocks each week.

I use a 300 & 600 grit stone before I use this and am very pleased with the results. I hope that helps.
