Well I had a water damaged 2 plug one so I thought I'd tear it to bits to see how they work. After trying to leverage it open with a crowbar and not getting very far, I hit it with a club hammer which just left a dent. I realised the plug in bit must be close to the other end of the flex so hack saw through it and pulled it out. It's a very simple device, just like any plug socket.
I then tried to use a crowbar to pry open the drum from it's spindle and it just would not budge. It was stuck solid. Then I remembered I had a Bosch Multimaster ripoff and cut what looked like a column of black plastic designed to push outward, hard, which must be what causes the drum to spin.
So, now, if I can't find the device I want at least I can build one, referring of course to that chart of how hot wire gets when coiled at thicknesses with certain wattages pumping through it and put a spring loaded retractor on it like the henry hoover and DIE FLEX DIE on things which get moved a lot like power tools and vacuum cleaners.
It was the stupidest idea ever. The flex SHOULD COME FROM THE WALL NOT THE DEVICES and have a lock switch to allow you to pull out more flex and a push button to retract it for you. Built in concealed casette reels.
Now when I get a home of my own one day...
OK, I need to goto bed and not stay up so late
