Awesome tutorial with great visuals and explanations. I am really getting a feel for this lock now and the intimidation I felt with the butterfly discs has gone away. Thank you for taking the time to do these tutorial, greatly appreciated mate, cheers
15:10 If you accept that the internal parts get greasy, just apply semi-thick grease into the ball bearings to "glue" them into place and re-building the lock will be easy.
Do you know if there's any commonly used terminology for the disk sleeve / plug / disk carrier part? Pretty much all DD locks have this part but everybody seems to call it with different name.
I still don't understand the principle behind the butterfly discs. Couldn't they just replace them with regular non-zero-cut discs to get the same result. What does the butterfly-shaped hole do?
Excellent video, very interesting indeed 👍 Question: in my latest video, 169, I show a Russian dual custody DD padlock. The front two discs, on both keyways, rotate further than the rest, am I able to tension off of the first disc? All the best to you and yours, hope you are enjoying the weekend 👍 🍻 🍻 CHEERS 🍻 🍻
THANK YOU - i'm no expert but in my experience with front tensioning locks - as long as there's a zero cut disk somewhere in the stack, and the front disk doesn't just spin around - you can use the front disk for tensioning all the rest of the disks, and then hold the zero cut and rotate the front one back into position. If you look at the playlist of dd locks - you'll see examples of - grabbing the SECOND disk when the front is a spinner; grabbing the first disk, and swapping, and some other similar manipulations. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tspXnYdzosA.html&pp=gAQB The basic principle seems to be: tension first available disk; set all the disks; when set, grab the zero cut wherever it is and then rotate back (CCW) that disk you were tensioning. GOOD LUCK!!
@@itsallinhow Absolutely brilliant thank you very much for that 👍 👍 👍 🍻 🍻 I've a feeling that it's rotating further than I'm used to. CHEERS, thanks again 👍 🍻🙏😎
I think ABUS could fix tensioning from butterfly disk pretty easily. Instead of having straight edge to push against rotation limiter, ABUS could make it a ramp so that if butterfly disk is rotated against the rotation limiter, the ramp would push the whole disk towards the sidebar. That would result in disk pushing the whole sidebar upwards into the groove in the lock body which should remove all feedback. Another solution would be to just get rid of butterfly disks because there's no reason to keep those zero cut when those are not used to tension the lock with the correct key. Why not use those disks for the correct combination instead? Because butterfly disks can be identified simply by looking into the keyhole, it makes no sense to always have those zero cut because it only allows the attacker to know 2 disks already.
