Freestyle model inspired by the old big superheavy round vault doors :)

That's a true masterpiece Maik

Great to see the video as pictures only can't show it off to its full grandeur- absolutely Brilliant!

Hey Max,

again thank you very much for your kind words. I am glad you like the door so much :)

Hey guys,

I made a new video about the remote combination viewer :)

Hey guys,

Its been a long time but I had to do my studies, and that took my freetime away... Butu today I thought "lets give them an update", so here it comes:

Currently I am working on the locking mechanism. Because of a member of this forum I got two Kromer combo locks and so I expanded my project far beyond my first "dreams".

On this picture you see the locking mechanism that is currently under construction just assembled so that you get an idea about it. In the center you have a block of steel (it is damaged and I will repair it soon) where a lever mechanism will be built in that locks and unlocks a bolt of the door (I think I told you that earlier). It is moved by unlocking the two combo locks you see left and right of this center piece. And beneath the locks you have the armor plates for them. Each lock will sit on a gear plate so that the locks are off centered to their spindle that you control from outside.



Here another view:


Here you see the rear side of the door frame. And on the left side the whole mechanism above will be mounted.



This is a view from above the door with the furniture it is mounted in opened.



Well I hope you guys like it and please ask questions if you have some :)

Best regards from Germany

Hey guys

Since Huw brought up the topic of pressure bar cams and their pins I thought I could present the solution for my door. So the cam is 74mm in diameter and made of mild steel. The eccentric pin has a roller that is 22mm in diameter and also made of mild steel. Maybe I make new ones that are hardened, but I am not sure. The pins are made of tool steel and are screwed into the cam. They sit in a reamed hole so the forces are not taken by the thread. The cam is mounted on the 32mm shaft with a M16 screw.

Here are some pictures.

Cheers

Brilliant, I knew you'd get it sorted Maik, turns out you already had it sorted!
Job done- all it needs is to replace that nylok nut on the end of the stud with a new one you've made from hex bar

74mm diameter cam, 32mm shaft with M16 threads- that's BIG!
I'm pretty sure M16 is actually the very largest metric tap and die I've got...

BIG thumbs up from me

[RiemannHypothesis]

Hey thanks man, I really appreciate your compliments

Yeah you are right about that ugly screw... I will replace it

Keep up your great works!

Cheers

After some hours of milling, filing and sanding, I finished the first anchor point on my door. Precision drilling also was necessary to mount this piece correctly and secure onto the remote viewer. The screws are hexhead M14 and I machined the heads a bit, as you can see on one photo. Also I tried to show how the eccentric grabs into the milled surface of the anchor point when the door is shut.



Tomorrow I will continue with the gears of the pressure bar. I have to make another part for it since the two handwheels are overlapping each other.

Cheers

That's brilliant Maik, every time I see your pictures I'm amazed at the scale of things...it's a seriously big model. You've done a great job on the anchor point, not an easy shape to mill out that, can see you've made a really neat job of it
