Modified Bike Lock (aka uber, epic, mega lock!) by angelabchua

Step 2: Cutting the lock

To get started, you want to make sure that you take good measurements of where you will be cutting and welding.  You know the saying, "measure three times, cut once!"

Remove bottom piece (the lock) so that you are working on the original U rod of the lock, and take off any protective rubber that might be on it.  

On each side, make a cut just above the locking ends of the rod, and just below the curve of the top of the rod, basically somewhere in the middle

Measure at equal points and mark where you will cut.

Using a cutting wheel, cut through the markings on the rod.   Originally I tried using a band saw, but it wouldn't cut because the rods were made of hardened steel, which means it resists traditional cutting.

That is a nice, custom lock that you have created. One hint is that most thieves carry either chain cutters or cable cutters. Most thieves do not carry both. So also use a chain.
Having said that there is no padlock like device that will stand up to two minutes of attack if a thief knows what he is doing. One answer is long prison sentences for the first instance of bicycle theft. Knowing that stealing a bicycle will be a life ruining experience will tend to stop most sane people from such a crime. Thieves are the greatest obstacle in getting people to use bicycles and not use cars. The theft of a bike is actually an assault upon all of society. It is in effect, a form of terrorism that alters society just as bombs and bullets do. Matter of fact more people die in bicycle thefts than in bank robberies. It is a serious crime but treated as a joke by the law.

Thanks! I totally agree. Scary to think people die over bikes though. In regards to this i'ble, this lock is mainly a cost effective way for us to refrain from buying 3-5 U locks, ontop of the cable lock.

we do use two types of locks for this set up (modified lock, and a cable lock). We also installed a motion sensor flood light right above the bikes. I want to attach a red LED light to it as well for added funsies. Then when the light goes off, and the potential perps see the little red LED, they think its a camera attachment as well.

Add it to the laundry list of "To Do" Projects in my house. :D
