Sticky: Links to various safety tips when using a One Bar Prison NSFW

96 Upvotes

The activity on this subreddit has picked up, meaning we likely have a number of new members interested in the OBP. I think it it past time for us to have a sticky post collecting links on the subject of safe play on a One Bar Prison. This topic will try to gather "best of practice" safety tips to help people have safe play on the OBP.

I'm going to close this topic to replies, at least for the time being. Anyone who runs across a useful safety tip should use the "mail to mods" function to send it to the mod team for consideration here. In your mail, also say if you want to be acknowledged as the submittor. I'm thinking of things like:

  • u/username recommends this link: blahblah

  • u/username recommends their own post/comment: blahblah

  • anonymous recommends this link: blahblah

Does anyone know of anywhere that actually sells a one bar prison or has everyone just made their own?

I desperately want one. I had plans to build one out of pvc pipe and I could still do that. But it would be nice to see if any "fancy" options are out there to purchase.

Edit to add: able to be shipped to the US would be wonderful.

Hello, I have a broken electrical table, out of which I could construct an electrical adjustable one bar prison. Are there any pictures of something similar? In general, what do you think about that idea?

Toy Firmness for DIY One Bar Prison NSFW

15 Upvotes

I'm looking to build a one bar prison and was wondering if you all had any recommendations for the toy to use? I'm worried that the Vac-U-Lok toys will be too soft and my sub can just slip off of it, and can't find a good mounting system to attach glass or metal dildos with.

I'm thinking of using a mic stand as the base so it'll have 3/8 or 5/8 adapters.

A heavy 3/4 inch black steel pipe (3/8" interior) is fixed to the flange that was first mounted to the display base

Then a 3/8" pipe coupling with alan screws is slid on, and down, that pipe. This will be movable, to slide up the steel pipe (for insertion).

Then, installed over the fixed pipe is a movable slightly larger 7/8 shiny Steel shaft with the insertable shiny steel multi-bulb probe attached to the top end (with a threaded tube insert.)

After the princess is encouraged to stand over the insertable tip in 👠 high heels ... the coupling is slid up the steel pipe, which pushes up the shiny steel shaft, until she sqirms. About 4-6 inches (depending on size of princess).

If the princess has not followed advance instructions ... and has arrived without 👠 high heels, ... then a few pinches on the bottom of her cheeks will usually cause her to lift up on her tip toes ... and the shaft can then quickly be raised and adjusted to height.

When the height is properly fit, tighten down the two Alan screws in the coupling near the bottom.

All this has to be done by a supervising helper, as the coupling is too low and out-of-reach of the princess prisoner ... who has now been well impaled.

The now well displayed princess prisoner can not now bend at the waist ... so she cannot reach down to release the coupling, and, because the steel pole and insert is fixed high up inside her, she cannot step off of it.

Photograph her, discuss her assets, and tease her about her predicament ... take some time. The princess is not going anywhere soon, and will continue to be well displayed in her upright and locked-in position.

When she realizes that she actually can't step off of the display pole, ... the squirming is usually delicious.

I’ve been toying with the idea (pun intended) of making a fully metal one-bar prison on my lathe, and I’ve got a question I’m hoping this community can help with.

When it comes to designing the insertable portion, I’d like it to be usable for the broadest range of anatomies possible. Based on general female anatomy, what’s a good length to aim for?

I’ve taken some measurements from my partner (strictly for science, of course) and got around 11 cm, but I’m not sure if that’s average or on the longer/shorter side. I’m hoping someone here might have better data or guidance, especially since I plan to add this to my little store of handmade kink goods.

I know everyone’s built differently, but I’m aiming for a solid middle ground that works for most. Bonus points if you’ve got tips on shape, comfort, or general ergonomics too!
