Neat security pin

[Raccoon]

The specification is 0.115 but there are variables in tolerance. If you accurately measured lab pins to .113 (i never tried) it's likely to reduce risk of crappy worn locks jamming pins. But they are probably both identical spec.

The pins belong in a dom ix ht, which uses the same weird-shaped bottom pins that can't rotate.
they are about .116" diameter, while a standard lab pin measured .113", so while they are just a hair wider, they fit fine in a regular LSDA lock.

Strange, I thought the non-rating pins are made because the pins are not in the center and the shear line is not rectangular to the pin's axis. But the other pin should match to that surface, otherwise the shear 'surfaces' always have gaps on one side and it's more easy to pick there?

I'd have to agree with mh: the DOM has a curved shearline specifically for pick resistance, does it not? Meaning one end of the driver would have to be curved (and splined) too.

But if they're misplaced, and not for the DOM - what *are* they for?

while some dom ix locks have 10 active pins arranged in two rows of 5, dom ix HT has only one row of 5 active pins.

I don't think i have any of the locks on hand but I'd be willing to bet that the shear line is centered and not curved in this case. If i have time i'll dig through our old stuff and see if i can find a lock to confirm this.

oh, and the non-rotating pins serve another purpose, because the bottom of the pin is not round at the bottom, it is thinner along the front-back axis of the lock, and the cuts in the key are often not round either. So even if the shearline is centered and flat, they still would have to be prevented from rotating.

A mate of mine from Slovakia remembers driver pins that are of a very similar pattern to those ones (you pulled out of your old DOM kit) when he was working back home in Europe. Evil things. However, it is sometimes the case that pins like these (and others like the serrated variety) that can make impressioning easier, has anyone tried impressioning cylinders with these driver pins installed? Just wondering how they react.

It looks like those type of pins would set up some kinda of conundrum for the key to even go in, i'm sure it worked most of the time, but it seems if you tried a bump key or something in that lock it would ruin it a bit.

MH and Linty:

Square or oval pins that can swivel?
on THIS TYPE of pin.... even a KEY would jam the lock
while opening.

you HAVE TO use round pins on something like this....


Gundanium:
Yeah, Id love to see someone pulling their hair out bumping this.
