Bolted to the wall

Here are more pictures of SFDom working over Mr Kristofer at at Serious Male Bondage

Mr Kristofer Bolted to the wall

Ultra-heavy wrist and ankle shackles are needed to keep Mr Kristofer in his place against a flat plywood wall in SFDom’s basement. The eye bolts are drilled into the wall and screwed in. Fucking hot if you ask me!

Cam cleat for self-bondage

In response to this post about a device that can be used for self-bondage, Metalbond reader Markus also recommends a cam cleat, available in boating stores!

Markus writes,

“You can go to a boating store and buy a cam cleat. You will have to come up with a base plate on your own. The difference is that unlike the Everlast product these usually come rated with SWL (Safe Working Load) and Breaking Load. You release the rope by puling UP and OUT of the cleat:

Markus continues:

“Generally speaking you will find lots of ‘pervertables’ in boating stores, usually made with high-end materials (all that salt water, you know) and at reasonable prices. And the sales people are usually very knowledgeable and will gladly help finding a solution when you describe them a non-boating problem. Just be aware that they usually will know what you plan to do with the stuff you buy, even if it’s not mentioned loudly!”


Thanks, Markus, for the information!

Update: Master Mike’s computer-controlled lockdown

Master Mike writes,

Here is the final piece of my electro magnet setup. I wrote this program that can be run from any PC with internet access. It basically controls the remote timer connected to the electro magnet system. There are two timers, the local timer that cannot be remotely controlled and is currently set to 8 hours, and the remote time that is currently set to 2 hours and can be controlled by the prison guard program. Both timers need to be active for the magnet to be on. The prison guard program can be used to set up cycles to reset the remote timer. It can also be used to optionally set release time after the execution of a number of cycles.

In the example below, the cycle time is set to 32 minutes and set for 7 cycles:


When 3 cycles remain, the program will release the magnet for 2 seconds.

This works out to be a maximum restraint time of 03:44:06 with the earliest possible release of 02:08:00. As you can see in the example below, I slept through the first two early release cycles.



The system is completely safe. The remote time cannot exceed the local time value currently set to 8 hours. If the internet connection is lost, then the remote time will finish out its 2-hour time and release the magnet. In the case of a power failure, the magnet will release.

That being said, there is no other escape.

Only Paul knows the password to access the prison guard program and relay. I cannot clear the timers from my iPad or by calling anyone else to release the timer. The only way I can get out is to call Paul. As for the bed, the left arm is held by the magnet, which has a 1,200-pound hold that is bolted to the floor with the wires running under the carpet. There is no way to pull it off. At the bottom of the magnet block is the key to unlock the restraints. There is absolutely no way to escape. The same system works on the gurney and for the cage.

There is also a camera for the guard to monitor and communicate with the prisoner.

Metal would like to thank Master Mike for sharing this information and sending these pictures!


Reader contribution: Master Mike’s self-bondage timer

Master Mike was inspired by the timer system made by Louis (see previous post, ‘Self bondage on steroids,’ by clicking here) and he built his own device.

Check out the pictures and information below from this guy:


Mike writes:

First off, a big thank you to Louis and the pictures posted on your site of his timer system. I got the same timer units and built myself a timer. I took it one step further and made it controllable over the internet. There are two timers, one I can set for the maximum amount of time before the magnet is released, and the other can be reset or restarted over the internet.

If it is reset, the timer will stop and release the magnet, if it is reset, the timer will reset back to the set time without releasing the magnet. There is also a camera with two-way communications so the remote master can communicate with his prisoner. There are numerous magnets around the house connected to different equipment.

Here are pictures of the timer, internet controller and me secured to the restraint bed.

The magnet has 1200 pounds of holding force and is bolted to the floor, so there is no pulling it free.

Here is a picture of the web page that controls the timer:



Metal would like to thank Master Mike for sharing this information! Very impressive, indeed!

Since he sent these pictures, he subsequently updated his system and sent further updates. Keep checking back to Metalbond to see more about this system.
