Pal of mine used to do this with his car when he lived on a 'rough' street. Lost a stereo and a window the first time. After than it was just two stereos lol!
I don't suppose anyone steals stereos any more for some reason...
Long been thinking that some tools should be sold with restrictions/registrations/etc.
Cordless mini grinders for one. I mean if a baseball capped, joggers wearing, gold chain totting 18 year old scrote turns up at the local B&Q to buy a cordless grinder, it's not rocket science to figure out he's not into DIY...
I've often been quite inventive when securing my tools in sheds and the like. Fabricating elaborate physical mechanisms independent of the padlock. Sometimes it can be simple though, a hidden sliding bar from the side, which pins the door and frame together, even if they cut the lock. I treat it as a challenge to keep them out 🙂
