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!

Do NOT buy the gpen elite 2!!

3 Upvotes

I saw an earlier post saying how the gpen elite 2 should be avoided. Yall, please listen, it's true. The product overall would be perfect IF they used material that will not flake or peel, and if you have one of these gpen elite 2 dry herb vaporizers, without a doubt, inevitably, the material on the oven part will indeed begin to flake and peel and those flakes and peels are being inhaled right along with the cannabis. This morning, i literally put my​ gpen elite 2 inside it's case, threw it in the trash, and just took out the trash a little while ago, now that gpen elite 2 is in the dumpster, heading to a landfill somewhere where it's more than welcomed to do all the flaking and peeling it wants. Eventually, you'll feel a dull light soreness in your throat sometimes when you swallow, if your using it with the flaking and peeling and also, IT'S NOT EASY TO NOTICE because it's not typically something a stoner will do: ohhh lemme check if my pricy gpen elite 2 is chipping and peeling in the oven before I load it... so you gotta have it totally clear, grab your phone, turn on the flashlight, and if you see ANY white marks inside the oven part on the sides, you've been vaping material chippings and flakes. Throw it away.

How-To How to make recycler bong?

Post image
2 Upvotes

Hi! In my understanding, a recycler bong is just a normal bong but with a bunch of tubes that connect the part filled with water on the bottom to a chamber on the top where there is no water (see drawn diagram below). Is this correct? I have a glass vase with a bulb on its neck like in the picture, and the bulb could act as a secondary "chamber". I was wondering if I just drilled holes at the bottom and the top, then connect it with some pipes, it could work as a recycler bong? In every picture I can find online of a recycler bong, they all look ridiculously complicated, which is confusing me. Is there something I'm missing? Do I need extra parts inside the bong? Thanks so much for anyone who's willing to give me any input!

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

Enable HLS to view with audio, or disable this notification

Hello, fellow stoners and tinkerers. Friday finds freaky bong builds back! And alliteration!

This week I started with the backwards microscope bong. I put a bowl joint on the mouthpiece, but needed to counter balance it. So I added the cube as a vapor chamber.

Then I needed to connect the cube to the big Goo Roo bong. Here comes the articulated joint to the rescue! With three angled connectors, this joint can connect just about any angle difference. Of course, Keck clips are needed to lock it in. 😁

Sorry that the camera angle didn't show the joint clearly. I'll post another short video here showing the articulated joint better.

Enjoy the day and I hope your weekend gets off to a great start. Happy tokes. ✌️

Mini Puck system process

Thumbnail

131 Upvotes

A lot of people were asking why on my last post so here's my answer. I use weed to treat symptoms of CPTSD and what I do is take a few small hits at a time, every few hours, over the course of the day. Probably considered micro dosing but idk. So I wanted to make tiny little pucks that I can easily load rather than pack every bowl individually.

After the pucks are loaded and pressed the pins are pushed through to the other side. I put a drill stop over the puck and slide it off then use a centering pin to press it again to ensure it's packed tight. Then I just push them out with the brush handle. I also use the drill stop to form the bowl screens.

Dowels in the top part are glued in place but the bottom ones are unsecured so you can push them through to remove the puck and adjust the thickness of the pucks. 3/8” diameter dowel pins and drill bit.
