I got this 1962 MARK IV MANIFOIL and I'm pretty excited. I'll make a wooden stand for it and put it in my safe locks display.
I'll try to manipulate it just for the fun of it. Even if the lock is still disassembled I think there's a way to check contact points. It just requires more time and effort since the cam is two pieces and can't be rotated back and forth without making an extra turn, but in theory it can be done. I'll keep you updated...

Cheers

Very nice, Femurat!

Holy shit Fem, where the hell did you get that?

I was talking to a guy from Chubb safes a bit ago and he was telling me how tightly controlled they are. Once they are made they are collected from Chubb (by the UK govt) and stored elsewhere until installed. If a Chubb technician needs to go and look at one they have to be escorted to/from the safe. Apparently anyway.

What do those 2 rollers do? The ones on the end of the arms?

Shouldn't this and your other acquisitions be in "lock porn"? Some pretty exciting pictures.

Please do a video spinning the Mark IV. Thanks, and AWESOME!

Wow! Nice!
It looks really cool!
I want also one!

Damn man, I have been trying to get one for a while now. You are one lucky guy!

That is incredibly cool! Congratulations on getting it and thanks for sharing with us

I'm a little late to the party. Does "manifoil" refer to foiling manipulation attempts?

Wow! Great question I never thought of that.

How are these locks rated? Is there a European rating system similar to our UL ratings?

What a piece of work! Wow... BEAUTIFUL... just beautiful. Congrats Femurat.

I know I was lucky

Thanks for the link flywheel, I saw it years ago and couldn't find it anymore. Sure I'll post pictures and maybe a video once it's mounted on display.

Hey huxley, the two rolls rest against the two cams. The cam is two pieces, one on top of the other, like if it was another disk. I'll try and explain it better, maybe with a video...

So I measured the spline and found out the door should be about 5 cm thick. I cut some plywood 15x15 cm and glued them together to get the desired thickness. I let them dry overnight...

....and so it begins! Nice

Can't wait to see it all dressed up

I sanded a little the plywood sandwich I made and then proceeded to assemble the lock. I thought it would have needed a stand but looks like it stands up on its own due to the "door" thickness. Here is the assembly sequence.
The lock works but turning the dial requires more force than I thought. I've checked and measured everything carefully but I may have made an alignment mistake. I'll double check hoping to make it turn smoother.

Here's an update about this lock. I removed the dial, the ring screws, re-installed the dial and rotate it while the lock was horizontal on the table. The lock turned smoother. I marked around the ring with a pencil. Then I removed the dial, put back the ring screws and reassembled everything. I also put a few drops of ptfe grease inside the nylon bushing where the dial touches it and one little drop on the two small rollers on the back of the lock and one drop inside the cam. The lock was still hard to turn.

I removed the cam again and and looked at the spline from the back... even if everything looked aligned the spline was a little on one side. I was not sure because it looked centered, but I used a small flat screwdriver as a gauge and found out it was just a little off center. I loosened the ring screws, moved the ring just a hair and tightened them again. Reassembled everything and the lock rotates smoother than ever.
It still requires more force than a s&g 6730 for example, but now it's smooth and regular.

I'll make a "dial centering tool" with a threaded rod and two threaded cones to help me perfectly align the next locks.

Cheers
