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

Hey folks! Since February i am working on a round vault door model completely made of steel. The door with frame weights about 300kg and the door itself about 120kg, and its diameter is 34cm. Im looking forward to build a remote combination viewer to which i have still many questions. I mainly used a lathe, a big drillpress and a big indexing head for the door. Some things, like the outer door plate and the crane hinge i have had plasma cutted out of a big 35mm steel plate. Well, there is still much work to do; the inner door frame is still missing, but raw material is already bought and the whole locking system is under construction. Here are some pictures 🙂 Best regards! Maik

Hey guys 🙂

I had a day off and so i spent some hours in my workshop to build my remote combination viewer 🙂 The good news is, that i have now all the raw parts and some of them got machined today. I think this thing will look epic 😃 I’m not sure yet but i have the impression that i could make both the door and the remote combo viewer water proof… If that works, it would be nice, if not, it still would be nice 😃

Best regards

Well guys, i spent some time in my workshop, cut many threads, got the lathe rollin for some hours, and so on… And since my design for the remote combo viewer has been finished some days ago, i got my fire on will to start building it 🙂

I wanted the combo viewer to be heavy and stark, and it will be that way 😃

Im now round about half the way of the building process.

Best regards

It’s looking good Maik 🙁y):

Thanks mate!

Im looking forward to continuing my work on monday evening 🙂

Looking forward to seeing more- theres some sizey chunks of steel you’ve machined there for it! What have you planned for the combination lock positioning on the remote viewer- will it be ‘on the side’ of the housing like the Cleveland Fed, as the spindle drive through the frame will then meet the dial at 90*- I’m guessing you’d go for bevel gears though but they’re a nightmare to cut- are you cutting your own? Over the years Ive made a few small spur gear sets, but only the one beveled gear a long while ago, to mesh with a larger crown gear I already had.
It was sheer luck I had a cutter with the right profile angles, as they cost a fortune and for me that makes it prohibitive for a one-off job. Lucky I had that one and it turned out the setting up for the angles proved harder than indexing and making the cuts!
Beveled gears aren’t easy to get hold of in small sizes though, even more so if you want them both on a 1:1 ratio as most have different face angles which means you can’t just use 2 crown gears as the face angles are often different Between crown and pinion.

Thinking about it though, and seeing what you’ve made so far there’s no reason why you couldnt put the combination lock on the front of the housing, so the spindle goes directly through the frame, like a conventional combo set-up except your spindle will go straight through the frame instead of the front of the door- would still be a remote combo viewer and it’d make things a lot more straightforward without the need for gearing and intersecting drive spindles. Keep us updated..

Yoo 🙂

The RCV will be positioned in a way that the spindle for the 16th bolt (thats what i call the bolt that is controlled entirely by the RCV) is in correct height. The 16th bolt is on the horizontal diameter of the door and it locks the door and it blocks the gear of the main handwheel which controls the 15 other bolts. So it has a double function: If somebody cracks the main handwheel and the 15 bolts, theres still one (thicker) bolt left (the 16th), which is independent of the whole door 🙂

The RCV has a direct spindle connection to the combination lock and the 16th bolt, so yes, this will avoid any complex gear mechanisms 🙂

I oversized the RCV, because it doesnt matter AND it looks cool 😃 It became way more stable and massive than i thought it would, but i personally really like it.

Here are some new pictures:

Yesterday i built the second unit 🙂 Now the most difficult work is done 🙂

Aha I see now! That’s brilliant- I was a bit confused at first but Ive read over a few times and fully understand what you’re doing now- that’s a great way of doing it, and you’ve given it your own unique design. It’s looking great and ‘chunky’ definitely rules on a door like that! I bet the RCV alone is getting pretty heavy as it grows. Great stuff I’m enjoying seeing it 🙁clap):

Thanks man!

Because of my infinite impatience i decided to clamp the whole thing to the door frame, just to get a look how it will look later 🙂

Yes the RCV weighs about 20kilogram, so about 40 pounds, and there is still the handwheel and another part missing.

Here are some pictures of the setup. Because of the lens effect of the camera it looks a little oversized, but in natura the size fits the design 🙂

… and im going to have some spare time later, and so i can continue my work 🙂 I already made a handwheel for the RCV and a dialer, but i have to do some modifications…

Huw Eastwood

Wow seeing those pictures gives an indication of just how big the whole door and frame is. The RCV looks great on there and I love the 4th photo with the door slightly open- looks amazing from that angle Maik 🙁y):

Is the inner ring large enough to fit a time lock?

[unknown]

RiemannHypothesis

Hey VaultDoors 🙂

Ah, you mean the inner door ring? It is about 100mm in diameter, so there is enough space to put a single time lock in it, and i have been thinking about that recently. But i couldnt figure out the mechanics yet.

Hey guys 🙂

A little update from the RCV 🙂 I mounted the hand wheel (the handles are still missing) and i machined the socket for the pressure bar! I clamped the whole thing to the frame again, to see how it looks 🙂

Have fun 🙂

Hey guys 🙂

Just wanted to give you a little update:

I pause the RCV for some days now, because the big work is done and the fine work has to wait until the mechanics inside the frame is done. After that i can continue building the RCV.

The next step now is the pressure bar. It will be a single one with a 32mm shaft (around 3/2 inch) and with 60mm (around 17/8 inch) excenters on both ends. Luckily i found a nice worm gear for the job and with that it will become a really nice looking, massive pressure bar system that will be fit perfectly into the design. The worm gear allows to actually get some momentum on the pressure bar and because of its blocking properties, the bar will remain in the desired position. Also because of the nice brass worm wheel and the polished steel worm it will look quite nice 🙂

After this i will continue with the fine mechanics stuff.

Keep it real!

Hey guys 🙂

I will continue my project in July and now all the plans and prints are done, i will get the two 40mm steel plates under the plasma cutter and i semi finished the pressure bar and the worm gear housing. Yesterday i made a colored scetch from the finished vault door. Here it is 🙂

PS: The door will be 4cm thicker (that means 16cm (about 7inches) all together).

Best regards

Hey guys 🙂

Today i got my plasma cut steel parts. So the project can move on 🙂 Here you have some pictures from the machined parts i made in the last months and you have the inner ring structure where the bolts will be hidden when the door is finished.

Hey guys 🙂

After some time i finally finished the remote combination viewer of my vault door 🙂 Here are some pictures:

Huw Eastwood

It looks great 🙁y): Nice and chunky but also has some nice radii and curves. Looks mega heavy- I can only imagine the total weight of it all now, the RCV must have added a fair bit, but just looking at the size and thickness of the inner ring…great work 🙁clap):

RiemannHypothesis

Heyyy!

Thanks man! Yea the total weight is 25kg, and together with the parts behind the doorframe it will be about 40kg 🙂

I will post pictures of the inner parts soon!

Best regards

Hey folks 🙁hi):

The last months were really full of work on my vault door and last Saturday i managed to finally get it up into our flat :8): It is still a lot of work to do on it, the door doesnt close yet and the anchor points are not finished. Also the bolt work is still not finished and the remote combination viewer needs a lot of work too 😃

BUT, it is still nice to look at it, so here are some pictures 🙂

Best regards
