Kromer combination locks

Haven't found a proper place and thought it would be a good idea to open a single thread for their combination locks instead of multiple.

At the moment I am trying to manipulate a Kromer 3011. It has three wheels and no anti-manipulation mechanism. This particular lock was made in 1993. Its size is that of the current S&G vault locks and is a descendant of a clone made by Kromer of the S&G 6550. Their locks can be quite easy to manipulate or the can be quite evil. There's not much middle ground. That lock here seems to be of the evil sort. After 5 hours and 10 graphs I have nothing! The variation of a graph is up to 1/4th of a number. I have attached a Vernier scale and try to do 1/32th. It is not easy to get the CP that precisely. Switched from RCP to LCP because it is a bit easier there.

Re: Kromer combination locks

I haven't yet had opportunity to get my hands on any Kromer locks... don't see them for sale much here in the US. Would like to learn more about them, and get one or two for my collection. Those graphs don't give much away at all, you've got your work cut out for you with that one.

Laser and mirrors will make your numbers easier to read.
Are these the ones you have to push in when dialled correctly?

Re: Kromer combination locks

Lasers will improve graphs only if the dial can be positioned as precisely.

This one is a standard lock. You probably mean that with the distance disc. See photo.

Re: Kromer combination locks

Possibly, I'm not overly familiar with them to be honest, i don't see any here. I remeber doing one where I think the knob had to be pushed. It was a good few years ago now and can't find my pics.

Re: Kromer combination locks

Opened that "Garny" padlock today. Lever is in the typical style of MagicModule Kromer locks and the size is also the same. So it seems Kromer reused standard lock parts to build a padlock. I opened it, because the padlock has an major issue. Turning left is fine, turning right will seize up because the fly of W3 is creeping from the area it should be. The cause is a really wobbly wheel pack. It must have been that wobbly when new. Maybe the wheels spun easier when new and the problem did not occur.

Re: Kromer combination locks

You literally opened the padlock!

It's nice to have a true combination padlock. I mean, it's a portable safe lock so you can manipulate when you're not at home.

Cheers :)

Re: Kromer combination locks

Are you able to fix that wobble and make it operate smooth again without using donor locks?

Re: Kromer combination locks

I'll try to put a ring behind the wheel pack to stabilize it.

Re: Kromer combination locks

The last four graphs of the Kromer 3011.

1) brown, W2: The locations with the dots seemed to have been the low spots. The are around 16 had the most defined walls, so I took it as a candidate, even so it was very wide.
2) green, W3: Nothing.
3) lavender, W1: Low spots around 30 and 59. 59 hat a not great walls, but at least a bit, and I beat 30 dead already, so I took 59 as current best choice.
4) green, W3: Open.
