Neat security pin

[linty]

found these in a dusty old dom ix kit, in my mind i call them abacus pins, the inner discs move side to side and up and down.

i haven't really gotten around to testing them too well but it's a pretty neat driver pin.

All of the round sections move independently? Sounds like a chalenge to me. When you got the false set the shape would change and it looks like they could become unset again. Be interested to see what effect they have on picking. Anyone know of a lock with these in?

[Tempature]

thats krazy

its like an insane version of serrated pins. ya, picking a lock with those would be quite a challenge i assume

Cool, thanks for sharing!

But I thought DOM ix pins always had that strange shape to make sure they don't turn inside their chambers?

Cheers,

ooooh they look fun. i wounder if you could retrofit them in a normal lock? Do DOM use standard sized pins?

Trippy. Looks like a crankshaft from an engine.

i also am sort of confused as to why they are round as well, I've seen the square corner dom ix pins elsewhere, but this is from a pinning kit which is clearly marked, just something my shop hasn't supported in years.
I'll look into it on monday and see if i can find more specifics.

Also, they look the right size for a regular lock, but I'll have to wait until tomorrow to test that as well.

they are drivers/toppins, so they would not need the corner to keep from rotating, that is only necessary on the bottom pin because the shear line is not top dead center, but off set. this means that one side of the pin is higher than the other at opening. without it, the shear line would be sloppy or impossible.
very interesting.

thinking about it again im not sure if it woudl be much harder than a spool pin. i mean you wont feel the discs sliding about so it would act much the same as a spool pin.

Unlike a spool pin, this pin would still have spring tension to it when it is false set.

Here's a peak inside a DOM i jsut did.

It shows how the are Key pins are cut incase someone wanted a look

[raimundo]

Ok, then, not the first time Ive been wrong

[Schuyler]

i pulled a couple of these out of a dom a LONG time ago, never put it back together.

mine was not a ix

[Kaellman]

Iv seen these in a DOM before. Cant remember where or when, but they sure look tasty!

[linty]

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.
