A new lock cable idea, was Lock Opened With Ball Point Pen
I've been wondering about this for awhile. Chain and wire cable can be cut
easily with either bolt/cable cutters or cordless grinders. But what about cable wound from both wire and kevlar? A bolt cutter would have a tough time because the kevlar strands would crush but not sever. Grinding would be difficult for the same reason, and because the cable would be too flexible. It could be cut for sure, but it would take longer, and maybe require stopping a few times to hack away with another tool, like a knife. Any ideas? Has this already been tried? Matt O. |

Yes, it's basically a good idea. From another life, I've learned that a good way to secure anything is with multiple devices that require multiple defeating tools. What would be ideal is something like a twisted or braided cable wrapped around hardened dowel pins or broken pieces of carbide. That is then covered with a thick layer of tar and then a nice vinyl (or whatever) cover to keep things clean. The dowel pins/carbide prevent cutting with hacksaws and the like. The tar makes a horrible mess when cuting with grinding type tools. The tar just makes a sticky mess and it also smells bad when over heated from the cutter/grinder or if torched. Of course, given enough time and energy, all locks can be defeated. All you want to achieve is maximizing the time to the point that the thief will decide to look elsewhere. On a side note: In Daly City, CA over the weekend. A city street was marked with many No Parking signs for construction about to begin on the said street. Cars etc. where to be towed away if parked during construction period. A bike was "Krytonite-d" to a street sign. The city workers needed to remove the bike as it was illegally "parked" and in the way. My friend witnessed them removing the bike from the street sign. How did they do it you asked? They cut the FRAME, removed the offending bike, and left the Krytonite secured to the pole!! ...one way to defeat a lock. -- Skuke Reverse the domain name to send email |

Boy, I'd be ****ed if someone destroyed my bike because it was illegally parked. I don't think city workers would casually destroy an illegally parked car, and I don't think they should do the same to a bike either. -- Ben Pfaff email: web: http://benpfaff.org |

However, I understand that is not the point and I'm not defending what was done. I too disagree with the worker's action. When told the story, I remembered the opening scene of the movie Backdraft. There was an expensive car parked in from of a fire hydrant and the firefighters needed access to it for their hose line. They smashed the driver and pasenger windows then passed the hose through the car to be connected to the fire hydrant. -- Skuke Reverse the domain name to send email |

Boy, I'd be ****ed if someone destroyed my bike because it was illegally parked. I don't think city workers would casually destroy an illegally parked car, and I don't think they should do the same to a bike either. I'm new to bike commuting, having started seriously during May, using some crappy cable locks. 25 miles roundtrip from Queens to Manhattan. May is Bike Month in New York City and there was a bike show at the Armory, where I bought my first real chain and lock, a Master. A good buy for $50. For the next three weeks I left the lock locked to a streetlamp in front of my job, using it during the day. That is legal in NYC. One day I had not brought the bike for some reason, but as I walked out of the building I glanced at the lampost and saw that the lock was gone. As was the lampost. All that was left was the base which rises about two feet from the sidewalk and has four big bolts where the rest of the lampost screws in. I checked with the local precinct. They had no idea what happened but did get a giggle out of it. Then I spoke to the building super, who told me that a contractor had removed the lampost during the night because it had a dent in it and would replace it with another. So I called the City. Tracked down the contractor. Got a call back that the guys had left it "locked" to a nearby bike rack. Say what? If there was a bike rack that's where the bike would have been. They just threw it away or took it. I did check the local cans but there was no big heavy chain in any of them. Still, I do get to tell the story of how someone removed a lamppost just to get my lock. True story. |
