My Kromer 3011 has similar solid wheels. I took mine with me in the car for a few days to see if the wheels move. I believe they did. Luckily most safes are not in cars or on ships. I believe these big locks are made primarily for reliability.

I will stick it in the van this week ( average around 400 miles per week) with all gates down, and see how it looks after 1 week.

I believe a vibrating poker as used to get bubbles out of concrete as its being poured was the vibrating bypass. Im not in the trade just now so cant test the poker, but have a customer who has.

If you make a scan, which numbers to you graph? Every second? Also every second and a half?

I scan every other number. If I read every two numbers and a half I save time but I may miss a good indication. Never underestimate a lock ;-)

Congrats for the opening and for the new Chubb, ratlock.
I'm confused by your graphs. (EDIT: I'm talking about the new ones on blue graph paper.) It may be because I'm a little tired, or I may be right.
A graph should represent the area between contact points. Our goal is to reduce that area. This is why I would put the 4 up and the 96 on the bottom.
Imagine the scale from the bottom of your graph going like 96, 97, 98 ...some empty space... 3, 4, 5.
It's like if you had a scale that starts from zero on the bottom and goes up until 100, and then goes on again. You only take the part that you need.
Hope this makes sense and help you.

Cheers :)

Cheers Femurat. I relised the number mistake after I had drawn my first graph, but thought to keep it the same for the second one, I was starting to confuse myself, by then.

If any one has a spare wheel for this one (the Panzer lock) Id be happy to buy it, or trade for it. It turns out im a wheel short. Great Ebay buy at the time.

Heres another bargain off ebay, its a cool lock, and looks good mounted up. But what a racket the clicker inside makes.

It has another wheel behind the cam wheel (closest to the dial). In this second wheel there is a groove roughly the same size as the drop in point.
There is a spring loaded ball bearing, that clicks into the slot and makes a loud "clacking" noise. Ohh boy what a row.

Has anybody removed the grub screw that holds the spring in place.? This one has glue or thread lock on it, and is pretty solid.

Nice lock, but would wake the kids If I played with it in the house.

That would be a Mosler MR 302/402. (302 has 3 wheels, 402 has 4 wheels).

Oldfast has done a great breakdown of one here : https://www.keypicking.com/viewtopic.php?f=100&t=8411

Yep thats the lock covered there in oldfasts thread. Sorry I cant show you the spline key in my lock for comparison, as I had to make one, (normal "L" shape) But agree that without the proper one, in time it will work loose, as there is a load of vibration caused by the clacker.

Here is a follow up on the 4 wheel chubb lock, where I put it in the van for 1 week with all the wheels at the 6 o clock position. (see previous picture)

After 5 days of my driving around Aberdeenshire in the van, the wheels have all moved anti clockwise to roughly the 3 o clock position.

Not really good, but at least it does not open without human help.

So now you can drill to open the lock?

With such a mounting the spindle doesn't have to be shortened.

I had to go to the extra trouble to mount the lock this way, as the threadding, and slot for spline key, only goes part way up the spindle.
