Picking 17th century cultural heritage locks

Saturday, June 30th, 2012

If the key to something you do not use every day is lost, it can take a little while before a locksmith is called. In this case it took them a couple of hundred years to find us!

But that is ok. I like mysteries, especially if I can help solving them. Last week was good for mystery solving and there still are some to be solved (edited 8-july: solved!) .

We were invited into some sort of museum where they had four 17th century treasure-boxes without key. They did send some images that allowed me to do some Research (via barrywels on twitter).

When we arrived we inspected the boxes and padlocks with endocsopes and decided they could probably be picked with simple steel wire bent in an L shape. Click on the image below to see how a similar mechanism is opened using two hooks. One hook lifts the hammer while the other moves the bolt.

In a little while we did mange to open a number of padlocks and one of the boxes.

Currently three 17th century treasure boxes are waiting to be opened and at least one of them contains a number of ‘heavy objects’. This is interesting, especially if you consider the boxes were used to transport valuables in ships.

Jord was asked to make a key for the lock(s) and that is quite a task with the special warding. Hopefully I can make a blackbag posting out of that too as it is an interesting process to create such a key. (more nice keys on http://www.duke.edu/web/isis/gessler/collections/locks-keys.htm)

The exact location of the remaining boxes has to be kept secret for now not to give anyone any ideas. There will be a follow up soon (after LockCon.US) and hopefully we can solve some more mysteries then.

What I do on vacation …

Sunday, August 1st, 2010

It has been a little slow with my weblog. Maybe it’s because I now use twitter to burst short messages instead of blogging, but the silence here does not mean nothing is happening. On the contrary, a lot is happening….

combination safe lock manipulation minor difference

First there was the safe opening weekend. I am sorry to be repetitive, but the weekend was a great success. Julian picked open four safes, amongst them yet another couple of real monsters , and lots and lots of other safes were opened in more destructive ways. I really was eager to try to open a safe by manipulating a combination lock, but failed as the only lock around was a four wheel lips lock. I am by now reasonably experienced in opening three wheel ‘group two’ locks, but this four wheel lips lock was just a little too much for me. We ended up drilling a hole in the safe and using a scope to read the combination.

I like a challenge and am using the vacation I am in now to study the four wheel lock(s). Jord Knaap was kind enough to let me use one of his cut-away demo locks for this research/test. The lock is neatly mounted on a stand, and as Jord had an eye for details, he even included the anti-drill ‘hard plate’ on the stand (it’s the yellow layer between the dial and the house of the lock). The interesting part is that these locks have false cuts in their wheels, and the position of the false cuts seems to be different on some wheels. Maybe there is a pattern, but it is too early to say … It’s just the first day of my holiday today ;)

Behind the scenes we are busy preparing lockcon (October 8-9-10). It’s gonna be good as more and more people from all over the globe are attracted to it, and the presentations will be high quality as always. And I will use this two week vacation to reply to some mails people have send me. I am running a little behind but will be back on track before the holiday is over …

Next stop: Safe opening weekend June 11-12-13

Monday, May 31st, 2010

One of the things I am really looking forward to is spending a weekend between the good old Dutch safe techs and their visitors. These guys are organizing yet again a fabulous penetration party on June 11-12-13. These parties are the ultimate for safe technicians as they cover the latest in state of the art in safe opening. Picking, drilling, manipulation, decoding … the works. And if you are into the legal safe opening business you are invited to join in! Just send a mail to Paul Crouwel if you want to attend.

And I am currently more focused on other things then safe opening but I definitely want to try some new toys I bought at my latest trip in the US.

Hope to see the usual suspects in less then two weeks!
