Rock Tumbling NEWBIE
« on: October 21, 2020, 05:50:33 PM »

Just started acting on a interest I've had for a while. Gems...pretty rocks...call it what you want. Saw a video/Ad for rock tumbling and bought a National Geographic tumbler kit. If you are not familiar with it, it comes with a bag of rocks, tumbling media and instructions. I followed the instructions to a tee and came away with rocks that were reduced to pebbles and some nice looking rocks that were only shiny when wet.  :dontknow:

While they were tumbling, I learned about different rock hardness and understand now why some were reduced to pebbles. You would think that they would include rocks of the same hardness so you get great results from "their" product and WANT MORE.   :laughing6:

After YOUR first tumbler how did figure out how to make the "MAGIC" work?  :WEEEE:

amrap,
I suggest that Youtube is your friend in this situation, as there a a number of videos on using a tumbler that I think would be a great help.

YouTube is my go to media for information on anything I want to learn about. I figured out one of the problems. The packets of grit they give you with the tumbler doesn't contain enough for step 1 & 2. Also, the packs don't tell you the actual grit #. Tonight I got a different tumbler and their grit packs were short too. I also bought a batch of grit from another company with the grit# on the label, compared it to the "cheaper" packs and they look the same (Other than #4 is white instead of gray)

I also bought a bag of agates and a box of petrified wood and will tumble them separatly (with the correct amount of grit) and should have better results.

Rock on dude!

I also bought a buffing wheel for my drill and headlight polish. I polished the best looking ones from the first ever batch. Here's the best looking ones:

Batch of flint going in next. Hopefully all the same hardness. Check every 3 or 4 days to make sure. Yea, NO BRAINER.

Update on the tumbling. I was watching some YouTube videos about tumbling and noticed people using different grits 60/90, 100/150, 180/200 and so on. Some people say 5 days for step one and 7 for the rest of the steps. Others 7 steps for all and still others go longer on each step. I don't recall any rock specifics on the differences like 5 days for Jasper and 7 days for opal. I checked the NG bottles of grit and it didn't state the grit#. The packets that came with the tumblers and boxes of Agates & Petrified Wood didn't state the grit# either. So I bought some other company's bottles that stated the grit# and to compare them.

They all looked and felt the same...not sure if you can see or feel the difference between 60 or 90 anyway. :LOLOL: However, the packets that came with the tumblers didn't contain enough grit on steps 1 & 2. Steps 3 & 4 contained more than the 2 tablespoons that most all of the videos say to use.  Also the other company included a LARGER scoop than the National Geographic one. It holds a tablespoon!

I saw 1 video that I think sums it up for the newbie. When he bought his first tumbler he bought extra grit. Do what the instructions say for your tumbler. After 3 days on Step 1, take a couple of rocks out and if there is very little or no change, add another scoop or tablespoon of grit. I did that with my second batch and that was when I discovered the shortage in the packets that came with the tumbler!  :thumbsup:

Marketing is about getting your money not about delivering the goods that work. Nice array of tumbling supplies at  a few dealers such as Kingsley -North. Between their offerings  a little education and a lot of patience you can make great stones.
