First at all, I'm not a locksmith, and I'm not very experiened in lockpicking. I just opend a cheep cylinder sold in 1€-shops, by raking, than I gutted this peace of rubbish, to show my friends, why they never hat to use such a so called securety lock at their property.
But I have a weird idea, to make pin tumbler locks maybe more secure and pickresistand, I want to discuss.
At my idea, the stack of the pins in every chamber will be as follows: The core-pin will be quite normal, but than I will insert a hollow pin, maybe made of that kind of tube, made for telescopic antennas with the outer diameter as the normal pins.
Al long as no key is insertet, the ombination of the core pin and that pipe ring pin will end up exactly to the shear line, so the core can be turnd, intil something stop that turning. Therefore I will use T-pins as driver pins with the smaller diameter is less than the inner diameter of that tube-pins. At last there is a spring loaded ball bearing in the very last chamber of the bible, and a little dimple in the core, that holds the core slightly turned, that the pipe-pins are undere the shear line, to prevent that e-pick from working, so that you have to turn the core a little to get in the key into the lock.
When you now want to pick this lock, and give tension to the core, you will rotate the core until all the pipe-pins are blocked under the shearline, so the core pins cannot be liftet up.
For the problem with that slightly turned core in normal position I have another idea: Make pin 1 and its portion of the core independent, so this will guide the key into the right position by a tight fit keyway until it is inserted in total. The real core than is in the blocked positiion first, until the tip of the key, guided by the keyway will rotate the real core in the right positin, to free the hollow pins.
When you try to pick the lock, you only give tension to that key-guide, that you then can turn around freely, while the real core is still in the locked position.
What do you think, will that work?
