Cruciform lock.. haven't seen a padlock with this mechanism before.
If you can make a dual tensioner then your best best is applying tension and either raking or SPP each pin.
Raimundo came up with a nice idea to make picks for these when I started a thread a while ago. Since I have the instructions to hand I'll post them again for the benefit of those who don't know.
In a long forgotten thread, Raimundo wrote:Make a pick Take two 7 inch long sweeper bristles, bend them together to a 90 degree angle, put a round tool handle inside the angle and bend them til the ends are parallel, (the tool handle keeps the inside piece from folding sharply and cracking,) clamp a locking plier down hard on the stack of 4 ends, leaving about the length of a key blade and a twist , and bind the 4 pieces together tightly, then make all of them twist by using two locking pliers clamped down hard, and make a 90 degree twist in all four pieces at once, with enough flat metal past the twist to file picks from, (you need to keep about half an inch between the pliers when twisting to give the metal room to shape without shearing. This will leave two double ended pieces that nest perfectly because they were bent together, You can put diamonds or mulitple diamonds, on the ends of these. they can be made to carry flat as they were bent, and then quickly made into cruciform with a keeper that is fitted behind the twist. of course sanding is the key to making them work.
Perhaps this will help you.
Oh yeah, if the plug needs to be turned only 90 degrees to open the lock then you will be fine. If you need too turn the key more than 90 degrees you will have to pick it more than ince, similar to tubular locks. When it gets to 90 degrees the pins settle-down in the next chambers thus ressetting the lock, hence if you need to turn the key a full turn to unlock then you are looking at picking the lock 4 times to open the padlock. Even if the lock only needs to be turned 90 degrees you will likely have to pick the padlock to lock it again - that's if you want to of course.
