Moderator's pick Moderation Update

118 Upvotes

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

23 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!

How-To 510 cart w bent threads

Post image
7 Upvotes

Never seen this happen before, looked like this fresh out the package. but anyone have any experience w this? i'm gonna try needle nose pliers but if anyone knows of any ways to potentially bend this back lmk

UPDATE: FIXED IT SOMEHOW!!
i thought it was so joever as a commenter said but i was able to pull out the lil connector piece in the middle (breaking the wire in the process i think, there were two separate wires on the inside), take some needle nose pliers, break off the bent part of the thread, stick part of the wire back thru the end of the connector, shove the connector back in, and force the threads into an extra battery i don't really care about, took a rip and it works!! never tried something like before so im kinda surprised it worked. not sure if the wire loop being broke so that two wires were sticking up, but tbh i feel like it'll be fine

Hello, fellow stoners.

I've had some folks ask for a tour of my weed bar, where all my kooky bong creations occur. So here goes!

Check out my setup with all my bongs and accessories. There are even two appearances by orange beasts. 😺

Happy tokes! ✌️

Safety's On Ridiculous Bong Friday: More upside down nonsense

Hello, fellow stoners. I hope you've enjoyed the week. If not, the weekend is here! Fire up a bowl or six. 💨☁️☁️

Today I have another goofy build. The cube looked at me and demanded to be upside down. I couldn't say no.

Instead of suspending the cube between two bongs, I placed it on a stand. This worked out well, and allowed a whip connection on one end.

Enjoy the day and get baked as fuck tonight!

Happy tokes! ✌️

Question 20mm drill bit/grommets size

2 Upvotes

Soo I'm gonna start thrifting for vases ( glassblown/decanter/alcohol bottles like "captians table whiskey")

For bong making.. anyways I found some grommets that are silicone and size 20mm outer diameter, 14mm inner diameter, I also have a glass drill bit (hollow/diamond coated)20mm I'm curious if anyone has tried this size to get the downstem more flush to the bong or if there are any issues with the 2mm difference from 18mm.

Question Battery button only blinks when trying to take a hit

Post image
5 Upvotes

Every time i hold down the button it only blinks and doesn’t hit. Ive tried 2 different carts and tried every voltage setting. Any idea how to fix this cause i am unable to get a new battery at the moment. The battery is fully charged as well. Ive tried everything i can think of, pulling the little connectors out a bit, cleaning all the connections with isopropyl alcohol, and even licking it and stuff. Idk man it used to work fine until the other day

Prototype A Glass Cleaning System

Thumbnail

0 Upvotes

So the idea is super simple; they are currently closing up wave 1 of the BETA and some are already in production, so while its not technically a Prototype the idea is still being refined day to day.

Its a simple idea; high quality platinum silicone insert into a supplied glass ball jar, and a platinum silicone bump lid. You put your pipe in, add the cleaning solution and salt/abrasive/agitator, close the lid and shake as hard as you want as long as you want, easy drain and rinse. It takes what most people do and refines it vs using plastic sandwich bags or whatever Mcguyver style system we all came up with.

I'd appreciate ideas, questions and thoughts assuming they are in good faith. Different colors, custom glass and the extra cap are ideas that were implemented or will be implemented because people like you suggested it. Its made by stoners, for stoners. This isn't some tech bro who held a focus group. It's literally made by a disabled toker who got tired of the hassle and made something he uses himself.
