As for freezing they reckon that the S&G bigguns (833 and 951) are the only two padlocks to withstand an attack with liquid nitrogen immersion for 30 mins.. Apparently all other locks will shatter, not sure how much of that is true and what's just marketing hype. So it depends what locks you're working on ;)


This is just speculation on my part, I'd love to be proven wrong because it would be neat to watch. However, from other materials I've seen subjected to similar treatment I suspect a well delivered sharp strike to a lock after immersion in liquid nitrogen for a little while might fracture a key component and cause it to open. But shatter? I'm just highly skeptical that would happen.

Re: Removing Anti Drill Pins

What model of lock are you making your cutaway with? If I knew I might be able to offer a suggestion.

It doesn't *seem* likely, does it? I wish I could get hold of some liquid nitrogen.. I did look into this a few years back, was ready to buy a dewar and contact a local gasses supplier to see if I could get hold of some but it seemed unduly difficult and risky.. Awkward questions etc (I don't think "I need some for home science" is a good enough reason :mrgreen:) but if I can get hold of some I've got a whole pile of Masters and other locks who are begging to be experimented with :D

My guess is a Ruko Garant :).

lol maybe someday :drool: but right now I got some new assa twin scandinavian ovals for dirt cheap that have a long pin down the front parallel offset to the pin chambers. Here is a factory cutaway of a mortice showing the type of anti drill pin. Image

I'm guessing areospace machining, aluminum, artificial aging chamber..... just a guess... and I'ma have to agree with Gordon... skip the N2 and just freeze the bugger and give it a little tap... if you're going to dip something, go for a master lock, let it soak for about half an hour and take a video of you dropping it in the driveway for all of our satisfaction.... please.... maybe 2 of em... locked to each other :)

Re: Removing Anti Drill Pins

After looking at your pic and then the Han Fey pdf ( https://toool.nl/images/d/dc/Assa-twin-part1.pdf ) The Oval seems to have the a/d pin in front of the pin stack it also looks like it's being retained by the pin cap. If this is so wouldn't the pin just fall out when you remove the cap?

Re: Removing Anti Drill Pins

Ohhh! Ok, makes more sense now. I thought from our PMs you -had- a Garant that you wanted to operate on, but then you also mentioned wanting one so I got a bit lost, my bad :D.

Dayum, that's nice.
