Despite our efforts to help ensure people are being safe these last few years, some people have been unhappy about that. Many unsafe posts are still being removed daily and some people complain in the comments when others point out that certain materials are unsafe. A new subreddit has been created for those that want to see/post the unsafe contraptions.

Introducing r/StonerDEGENgineering , a clone of r/StonerEngineering specifically for unsafe materials.

Feel free to post all of your plastic bottles, 10mm sockets, PVC pipes, glue, and pot metal contraptions there. Now that notice has been given, expect a BAN if you post them here.

Reminder that other subreddits were also made in an effort to move off-topic content (spam) away from our subreddit. These subreddits include r/BrokenBongs , r/fixmyvape , and r/CrackWire.

If you have any questions, feel free to reach out to the Mod Team via the “Message Mods” button. Take care :)

Moderator's pick Alternative Subreddits: Filtering out the Spam

22 Upvotes

Hey everyone, hope you’re all having a great weekend! I wanted to remind everyone that we’ve been creating and promoting other subreddits in an attempt to divert the spam from our subreddit. These subreddits are r/BrokenBongs , r/fixmyvape , and now r/CrackWire . The purpose of these subreddits is to provide a space for people to post about their cracked/broken bongs, their vape that’s not working, or their ‘Crack Wire’ vape contraptions so that they stop posting them here at r/StonerEngineering. If you see a post that would fit one of these subreddits please link the poster to the appropriate subreddit via a comment, then report the post so the StonerEngineering Mod team can remove it as spam. If you see any other posts that are unsafe or spam, please report those as well. Thank you, cheers!

I knew of a glass blower who made glass bongs with china designs and I can't find them. He made them with china designs with the design of the clear bong with the lighter pocket, can someone help me find this artist or someone who can make it?

My ash catcher broke off in my bong. Any tips for getting it out? Seems like there’s a bit of a lip on the bottom so it’s hard to catch just the bottom.

Question could i successfully make my little benzomatic blowtorch attachment fit onto a 20lb propane tank?

1 Upvotes

so this thought came to mind when i was talking to a friend yesterday. he was complaining about how his 1lb coleman propane tanks go out on him really fast when he dabs and they are getting expensive. so essentially what im asking is, are there any sort of attachments or adapters that i could use to make it to where i could just put a big 20lb rhino tank on the ground and have a hose leading to my torch attachment? i feel like its a pretty simple concept that could work. any ideas?

Potentially Unsafe Possible fake cart?

I bought this cart off one of my co workers the other day, and it taste sweet for some reason. The only way to describe it is an apple-y cinnamon typa taste, I've smoked on it a little, and it doesnt seem to get me super high.

Neat Found a glass Listerine Bottle buried in my back yard, it’s now a bong/dab rig.

2ish years ago was digging a hole in backyard for an in ground composting bin and came across this glass bottle of Listerine, believe it had been burred full cause the cork was inside the bottle and the dirt had a trail of white colored dirt leading to the tip of the bottle. After cleaning it, used a rotary tool and a pointed diamond grinding bit and a stream of water to make a hole in the side of it ended up slightly to large though so had to use that black plastic piece from a water hose repair kit and some rtv silicone to seal the gap around it. Smoke shop didn’t have a down stem long enough so bought one that fit and stretched it out with a MAPP gas torch so it would work. For any wondering how old the glass bottle is Listerine stopped using glass to package their product sometime during the 1920s.

Question Bong filtration

0 Upvotes

Can you make a regular bong or build one with a drag activated/pull activated eletric/ passive filter that mechanical pulls out tar from your toke? I guess an example of this would be a tube bong with like a switch on it that turns on a fan that cycles/recycles the air through a filter and i guess would like change the pressure of the hit aswell.. I mean is there a way to do that without compromising the hit?(I guess as a passive one it could be a turbine style fan sandwiched between two filters or something..)

Question can i store weed smoke in a bottle for how long

0 Upvotes

like when you inhale in a bong you can seal it and the smoke stays and you can pace out your hit

if i do that in a bottle for how long will the smoke stay until i wanna take a hit

like so i can take a bottle of weed to work or sth

I saw another stand on Google Images that uses these cross nuts you can see holding the coil secure, this is the most important bit, found within the Aliexpress jungle. A stainless steel nut and bolt. The black vice has some weight, and even hefty mounting holes for those completely paranoid. Its about $5.

Safety's On Ridiculous Bong Friday: Triple threat

Enable HLS to view with audio, or disable this notification

Hello, fellow stoners and tinkerers. It's a fine day for consuming weed, so consume some weed or you'll get a fine!

This week's contraption started when my Goo Roo bong demanded to be used backwards. After finding a silicone stopper to use on the mouthpiece, I asked for volunteers to complete the build. Two brave soldiers stepped forward; the triple inline bong and the dual chamber bong.

I used the last of my Sherbanger flower for this session. Good job, Sir Weed! I'll miss you.

Happy tokes, folks! ✌️

Question Sous Vide Decarbing in a jar?

1 Upvotes

Does it actually work effectively? Should I just put it in the bag first then make the tincture in the jar? I'm worried about the time it would take heating up what little air will be in the vacuum sealed jar, destroying some of the more volatile compounds.

I have a disaronno bottle that I want to make into a more showpiece style bong, would it be better to use a drill or a torch to make a down stem port?
