assa twin help please

[Baloopaloop]

hey peoples, I have an assa twin that I've been working with and I read up some stuff about it at tool to find out what was giving me so much trouble simply picking the pins. I took the sidepins out and left just three pins in the lock and I'm having crazy difficulty still. I figured out that it must be the counter milling. Other than extreamely light tension, are their any other ways to get around this?

If you look at the plug, you will notice that the third pin stack from the front lacks the counter-milling. So, if you can try and wait until all the other pins are set before setting that stack. Additionally, use very light tension to keep those drivers from catching in the counter-milling.

The Twin series locks don't have a set milling pattern; it is random, including the type of counter milling. Everything in the Twin series requires a high degree of practice and skill to pick even the pin-tumblers, let alone the sidebars...

great so, I don't get exactly how the countermilling even works though. Is it just on the plug? Info on everything that has to do with it would be great

Counter-milling means that in the plug chambers instead of a straight through hole that they milled (cut) out rings to give it a ribbed/serrated effect. A good picture from the Twin series is here:

When you put tension on the lock to pick it, the spool pins are designed to catch onto the counter millings to provide pick resistance in the same way that a security pin normally catches between the plug and cylinder. The counter-milling is better because it is much more sensitive and makes counter-tension (a technique to pick spool/mushroom pins) more difficult to pull off.

Which lock are you working with? There are quite a few in the Twin series.

Twin 6000 I believe. thanks for the info there. So then is feather tension the only way of working around it?

The Twin is a demon wh0rebeast and it will break you.

So yes, feather tension.
