TAG：电磁锁自缚、防毒面具。这是一对圆形电磁铁，每个电磁铁都包裹在重钢中，橡胶绳从每个电磁铁连接到控制箱。每个磁铁有150磅的拉力。在这段视频中，我穿着厚重的橡胶StudioGum套装，脚踝伸开，被地板上的螺栓锁住。我以展开鹰的姿势躺下，用磁铁固定一对钢盘。每个钢盘都系在我手腕上的镣铐上。一旦两个磁盘与磁铁接合，我就会保持在展开鹰的位置，直到控制箱中的计时器结束循环。OK you guys. This might be my best bondage invention. It's a pair of round electromagnets, each encased in heavy steel, with rubber cords that run from each electromagnet to a control box. Each magnet has 150 pounds of pull strength. In this video, I'm in my heavy rubber StudioGum suit, with my ankles spread and shackled to bolts in the floor. I lie down in a spread-eagle position and engage a pair of steel disks with the magnets. The steel disks are each attached to shackles around my wrists. Once the two disks are engaged with the magnets I'm held in the spread-eagle position until the timers in the control box end their cycle.

The timers are mechanical, not electronic, because the time duration is easier to set and much less prone to making a mistake. The two timers are wired in series, so if one timer stops working the other timer will continue to count down and open the magnets.

The magnets operate on 6 volts DC at around 1.5 Amps each, and have a pull strength of around 150 pounds, which I actually tested with sandbags. Each round steel disk (or armature) is around 3/8-inch-thick and has a 1/2-inch hole in the center where an eye-bold in securely threaded. Each electromagnet is recessed inside a heavy steel cylinder with a flat plug at the far end which another eye-bold threads into, along with an industrial wire mesh cord restraint.
