I bought my son a NatGeo Rock Tumbler for Xmas and I have lost the instructions! HELP

The company below supplies these kits:-

I'd try going to this site, scrolling down to the bottom of the page and clicking on their "Contact us" link. Ask them if they can supply you with a copy of the instructions you need.

Directions for the NatGeo tumbler are apparently non-existent online. However, I did find the video below to be quite useful. It has some general tips that work with any brand of tumbler. I hope this helps out!

just bought a rock tumbler for ToysRus but the barrel does not rotate i think that the toy is defected please let me know what else i could do to make the toy work thank you

I used to have exactly that same rock tumbler. I have a bunch of polished rocks out in my garden that the kids and I made with that thing.

I don't have the instructions, but there are some perfectly great generic instructions on the geology.com web site: http://geology.com/rock-tumbler/rock-tumbler-instructions.shtml

I used these directions with great success.

Hi, We got the same tumbler this Christmas. You might be able to get an manual from [email protected]
To get started though, Step 1 takes 2-4 days, step 2 4-7 days, step 3 2hrs, step 4 2 hrs.
To start day 1
1) rinse stones with water and fill barrel with no more than 8 oz of stones
2) Add step 1 course Grinding Powder
3) Add enough water to cover stones
4) tighten (snugly) cap on barrel to prevent leaking
5) Be sure barrel is clean & dry. Fit barrel into tumbler (fits correctly only in 1 direction). Cover barrel with safety dome.
6) Attach DC plug to tumbler and plug in.
7) Push on/off button
8) Push # of days button timer.

Extras
They suggest using a lubricant on the inside rim of lid to help removal.
Once you start the tumbling do not turn it off and leave it off - It will harden like cement inside the barrel.
It is loud so place it on a towel to help reduce noise and put it where it won't bother anyone.
Good Luck and Have Fun
