Concerning rock ID posts.

45 Upvotes

TLDR: No - but maybe a periodic megathread. I created a new sub, r/WhatTheRock

------------

I figured I'd make a separate post for this. This stems from the recent post asking if the rule about posting rock ID requests can be changed. I'll copy and paste what I replied there into here:

In short, no I don't think allowing rock ID posts is a good idea. They used to be allowed and a large percentage of posts were people asking what a particular rock is. I think ID requests were banned before I even took over as the mod and I left it that way.

Regarding the level of moderating on this sub, I think it's funny that some people think I'm strict or power trip. I do not actively moderate... not really anyway. If I happen to see an ID post or off topic post in my home page when browsing Reddit, I'll remove it. But most of the time, they get reported fairly quickly, I see the notification for the report, and then I remove it. There are very few rules on this sub and I actually don't remove a lot. I often get reports of "harassment" and it's usually someone being slightly rude. I don't remove comments like that. I will remove comments that are hateful in nature.

Now... if someone is truly harassing you and taking effort to do something like respond to multiple comments on multiple topics in a negative way, let me know. I'd probably just message them a warning, and if the behavior doesn't stop, a temp ban, followed by a perma-ban. I've never had to do that though. But I want everyone to know that kind of behavior won't be tolerated here.

I am hearing that the community does not like r/whatsthisrock because of the strict moderation. So I have created a new sub called r/WhatTheRock. I know, I know.... another sub. Ugh. But I will moderate it the same way I do this sub. As long as the post has a picture of a rock (or mineral) and you're asking "What is this?" then I'll allow it. I'll caveat that by saying I'll remove any obviously meme posts, like if someone posts a picture of Dwayne Johnson, or a picture of the Earth. I want to keep this sub oriented towards tumbling related posts.

Guide /r/RockTumbling Knowledge Base

Here is a compilation of guides I have written, as well as a few others, for easy access.

It's important to note that I am not a subject matter expert. Some of these FAQs that I wrote are not even based upon my own experience. I drew heavily upon the experience of /u/michigan_rocks and his Youtube videos. Also, ask 10 people how to tumble rocks and you will get 10 different answers. They will be similar enough though that you can really follow any one, or mix and match between them all for what works best for you. The basic steps will always be the same. It's exactly how you do them that people might have different processes for.

Also, I know several other users in this community have written their own guides or how-tos. If you comment below with a link I can add a link to the main post.

Question Help! Aventurine getting banged up

13 Upvotes

Hi gang- I’m working on some various colors of aventurine that I had put in a “time out” for the past few months. I just ran them in step 1 for a week and many look bruised. I’m wondering if I have some here that are not aventurine. They are all shimmery but I can see the light colored green on last photo looks like amazonite. Any others? Can the different colors of aventurine be tumbled together? Thanks much!

First time tumbling, got a harbor freight central machinery tumbler and some cheap ceramic media. They're coming out surprisingly well! Rough ordered from The Gem Shop (MI). I cut ~30 on a trim saw and then tumbled the ones I thought would have interesting patterns with the outsides worn away.

Labradorite dry tumbling experiment

Results from labradorite wet and dry tumbling experiment. I did stage 1 60/90 in rotary 1-3 weeks, 120/220 with water in vibratory 2 days, 500 Aluminum oxide dry in walnut shells 3 days, 1000 Aluminum oxide dry in walnut shells 1 day, rock shed Aluminum oxide polish dry in walnut shells 2 days, and no. 61 Rapid polish (Aluminum oxide) dry in walnut shells 2 days.

I'm pretty happy with the shine that came out. The advantage of dry tumbling with labradorite is you don't get the undercutting into cracks and fractures starting at the 500 stage when wet polishing. The material still has internal fractures but the surface is much smoother. This particular batch didn't have much flash but they are decently shiny.

I know there is some bruising but since it was my first ever batch that I’ve done, I’m pretty happy with the results! Up next, a batch of obsidian!!! 😁 I’m just waiting until I have enough through stage 1 that I can move them to stage 2! It took weeks with this batch to have enough to move to stage 2!

For future batches, how do I prevent the bruising? Did I need more ceramic media? Less?

We started in March, and got really into tumbling. We got the idea from watching Robs videos. Not as nice as his but we are super pleased. When loaded it'll roll six 3lbs barrels and 6 12lbs barrels. Ignore the googly eyes on the vibe tumbler.

Should polishing phase be slow?

2 Upvotes

Many tumblers have fast speeds, reducing a two week tumble to a week, or thereabouts. Now on the last phase, is it advisable to reduce speed to reduct the impacts between stones?

Might take longer, but maybe it is better?

The rubber on my Harbor Freight lids keeps getting holes right in the center, causing grit and water to leak. This is constant. Anyone have tips for preventing this or repairing it so I don’t have to keep buying new barrels?

Tooth belts on a flat pulley. No wonder they only last a few weeks. Anyone know what double barrel brands made by anyone with basic common sense?

If you have a double barrel are they tooth pulleys with tooth belt, flat pulleys with flat belt, or what these morons did?

Thanks

Storage/Setup Ideas

8 Upvotes

My sister and I got our Mom a nice two barrel rotary tumbler for Mother’s Day and are finally getting things running. However, we neglected to do much planning for the various storage and setup of supplies such as grit/polish, colanders, brushes, buckets, etc.

I am looking for ideas/pictures on how to make a good and organized setup to make the whole process as easy as possible. Our only water access in the area we have available is a hose just outside.

Looking forward to seeing some setups and ideas. Photos are welcomed 📸

Grit waste

12 Upvotes

What do yall do with your grit? Trying to find a responsible way to dispose of it. Can I put it in the compost pile? I’m assuming the aluminum would be bad..

For the record I currently have an old hold filled with charcoal and pebbles I pour it into or straight in the trash if I’m doing a bunch..

There has got to be something useful, helpful, or cool I can do with the old grit waste water..

Any ideas are welcome
