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

[RiemannHypothesis]

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!
