User questions & answers

Question:	Can i buy extra grit without the rocks. we have many rocks from "mining" gemstones that i would love to polish. what do you recommend
Answer:	Hello, currently, our GUI app can only run on Linux and Windows platforms. We are developing an Android app, it will be released in two months. THX!
Question:	What pound tumbler is this product
Answer:	Hello, RaspTank does not include the Raspberry Pi board, you need to buy the Raspberry Pi yourself. You can connect the keyboard and mouse directly to the Raspberry Pi to program. You can also use the PC to connect to the Raspberry Pi to program via ssh.
Question:	What the difference between this and the starter kit
Answer:	YES.
Question:	What is the power consumption of this unit over a week of continuous use? (in usa on 110v). thank you
Answer:	Yes, it can turn left and right. The calibration wasn't exactly straight forward but after a few tries was able to find and acceptable 'straight' setting and it drives okay. Speed is normal RC car speed, slightly faster than human walking so maybe 5-10 mph tops. The lag between the app and the car is a bit of a problem and at higher speeds you end up running into stuff a lot.

User questions & answers

Question:	Are the stones ethically sourced
Answer:	Ours has never done that and we fill it about half to 3/4 full with smaller rocks is the belt getting caught up or falling off?
Question:	Are any of the gemstones crystals
Answer:	Our Rock tumblers are currently manufactured in China.
Question:	With my rock tumbler kit i received 15% off my next purchase of refill pack. The savings will not apply to the 5# refill, why
Answer:	Yes you can use your own rocks, just keep in mind you will want to tumble like kinds together, as hard rocks could chip and bruise softer rocks.
Question:	Can anyone tell me how this comes packaged? is it in a brown box and inside that is the item? I'm not talking about the amazon box
Answer:	I am a 39 year old rock climber with a full tool shed, it takes me about half an hour to finally get open. I'm probably in the 99th percentile in ability to open a jar; this is ridiculous.

User questions & answers

Question:	Where are stones from
Answer:	I don’t have a tumbler - I spray them with Krylon triple-thick crystal clear glaze. They turn out super shiny & absolutely beautiful!
Question:	How do you put the rocks in the earings
Answer:	No you shouldn't any stones rocks or minerals ending with ite should not sit in water they will eventually disintegrate examples flourite calcite selenite etc sorry
Question:	Why does my rocks not polish after 10 days
Answer:	Not at all. One of the unique properties about fluorite is its fluorescence under a uv light which not a single piece does in my order. If I could pose a photo of it next to actual fluorite you’d be shocked.
Question:	The instructions say to use 4 tablespoons but the packet contains less than 1 tablespoon. Shoud I buy more or is i packet enough
Answer:	The instructions for the Tumbler does not give a specific weight. It recommends not filling the Tumbler barrel more than 1/2 to 2/3 full. If you overfill the Tumbler, the built-in sensor will automatically protect the motor inside by turning the Tumbler off. It further recommends if this happens you should remove some of the rocks.The grit to be used in the Tumbler comes in premeasured packets for the Tumbler size itself. I hope this helps.

User questions & answers

Question:	Will these help protect the more fragile stones? Some stones are snall and somewhat thin and have a tendency to splinter or break
Answer:	Not 100% but they keep the stones from hitting each other real hard.
Question:	I understand that I use grit with this, but do I still use water? Or does this replace the water allowing for a dry tumble
Answer:	You still need to use water.
Question:	Can this be used to give clean, rectangularly cut glass a "seaglass" look? It is a frosted look with edges that have been filed down. Thank you
Answer:	The pellets will cushion the glass in the tumbling process, but you will need to add grit to help shape and round the edges of the glass. Hope that helps!
Question:	What is used to give the stones a shiny finish
Answer:	The shiny finish on stones is done during the polish stage, and the final polish is done during the "burnish" stage. Burnishing is done using, not grit, but soap.

User questions & answers

Question:	Mine didn't come with an instruction booklet. Where can i find one online or request one
Answer:	Hello, The Hobby Rock Tumbler can hold 1lb of rocks. Comparably, the Professional Series Tumbler can hold 2lbs. Thank you for your inquiry, National Geographic Toys Customer Support
Question:	I get an error code everytime I try and run it doesn't anyone know why? I hardly have anything in it
Answer:	There are two main differences:The Hobby Rock Tumbler has a rubber tumbling barrel with a stainless steel cap, which reduces noise and is more durable. The Starter Kit Rock Tumbler has a plastic barrel. The Hobby Rock Tumbler also has a keypad for setting the number of days you would like it to tumble, where as the Starter Kit Rock Tumbler's setting options are on/off. Thank you for your inquiry.
Question:	what is the warranty for and how long is it
Answer:	This takes .3 Amps, so (watts = amps x volts) OR watts = .3 x 110 which equals33 watts. Now for one week would equal 33 watts x 7 days x 24 hours =5544 watts or 5.54 kilowatts for one week.At $.16 per kilowatt it comes to $.89 per week.
Question:	Can you confirm the voltage rating of the power cord? only 110v or up to 240v? thank you
Answer:	Hello, you should run code/server/sever.py on the Raspberry Pi and code/Client/RaspTank.py on the PC(Windows or Ubuntu Linux). Please refer to these two videos: https://www.adeept.com/video/detail-70.html https://www.adeept.com/video/detail-53.html If you have other questions, please contact Adeept support Team by Email.

User questions & answers

Question:	My kit has 2 "step 1" packets of grit media and is missing "step 2" Should i just move on to step 3 and tumble longer? Any tips
Answer:	They fit both hands
Question:	what stones are in it
Answer:	Thanks for the question. Yes, they will , this glove works on iPads as well as other universal touchscreen devices.
Question:	Tumbler stopped spinning, seems to still run but it only does one spin and seems it cannot push the barrel futher. Is it a weight issue or something
Answer:	I have very small hands too but it fits ok. It’s not as tight as it probably should be but it’s not so loose that it gets in my way or falls off. As long as you don’t mind it not being skintight then I think you’ll be fine. Just an FYI- when I buy gloves for the winter even the small size is too big on me.
Question:	Is there a replacement rock tumbler barrel available
Answer:	Yes ,it can work with Cintiq.
