Do X - The Resurrection Of A Legend in Real Life, VR and 3D-print

    I will not do much more else during the next months or probably years. So I decided to make a seperate thread about this very special issue.

    upload_2020-1-6_1-23-59.

    At July 12th 1929 the Do X took off at the first time. At that time she was the biggest airplain worldwide for more than 20 years. Additional she was build completely from metal wich was new. Only three were build and no exemplar survived. Even the blueprints are lost except some drawings and a lot of photos. We are a few enthusiasts who want to make a 1:1 scale model of this masterpiece of engineering. We collaborate with Dornier Museum in Friedrichshafen and with some universities in Baden-Wuertemberg/Germany. Currently more than 30 students work at this project.

    I stumbled about this project by accident. I loved this airplane since I was 8 or 10 years old (1962/1964). So I searched the internet for some drawings or contacts to build my own model of it for VR. Immediately I found Peter Kielhorn, who is the spiritus rector of the project. And TAHHHDAHH! he got pretty good 3D-models already. He planned to make a VR-version as well. So we quickly came together and decided to combine our activities.

    Thanks to all the data I could make some high-resolution pictures for a photo book, a few raw VR-presentations and some early parts for a 1:43-scale model of the forecastle. This is our first waypoint. Something like this:

    Fortunately my old WANHAO printer died and I bought a new ENDER 3 pro for 250 Euro. This baby is way better. So I could print the first parts:

    Tomorrow an editorial journalist of our local news paper will visit me to talk about the project. Especially about VR. But I can show him the ongoing of the 3D-printed model as well.
    In early April we will be at the AERO in Fridrichshafen. We will be part of the presentation of Dornier Museum. I hope to finish the 1:43 model until than. We will be able to offer two Oculus Quest and my Oculus Rift. No clue if we have enough room for such a blast ;-)
    And I hope to meet David Dornier, director of Dornier Museum.

    Printing lots of parts:

    Well, my first attempt to make a model kit, everyone can print and build. That's a big chellange! I had low success so far. I have to rethink what I really want to publish. For now I'm working at a model of the forecastle of the Do X at 1:43 for our presentation at the AERO in Fridrichshafen in early April.

    Well, long silence ...
    I canceled this 1:43-project. We think about a 1:10 scaled model meanwhile. But that's not our main focus.

    Next week Peter Kielhorn and I will ride down to Hungaria to visit Sophia Borbely. She owns a replica workshop and will build our 1:1 scaled model of the Do X. That's a huge project and will take several years. Especially because we need the money to pay her. During last summer I reworked rib 44, wich is one of the biggest, from former students work:

    6 meters tall and 4,6 meters wide. The guy standing in the door at passenger's deck is a 3D-scan of me. Above is the bridge. We got photos of the first parts already and hope to see much more during our visit.

    Sophia is a professional. She engineered Amundsen's Dornier Wal for the Dornier Museum already and her husband Karl Birczak manufactured it:

    I hope to learn a lot about manufacturing such 1mm aluminium films. Chocolate paper even. I come from heavy machines like excavators, dragline diggers and bulldozers. 20mm thickness is still metal sheet. But 1mm? That's thin film! And rivets? Not much clue of that yet.

    We hope to exhibit rib 44 in Dornier Museum at the end of this year. Currently we discuss the requiered space for it with the staff ;-)

    Parallel we talk to Joerg Neumann from Microsoft. I flew the Do X already in Flight Simulator. She is not available as addon yet because it's a WIP. But hey, its fun!

    hehe.... 1mm aluminum is ~ 0.040 inches (we say Fourty-Thousandths), that is about as thick as I work with, I commonly work with (on the plane I am building with my son as well as at my actual job) .040, .032, .025, .020, .016 I do work with thicker, such as 1/8" (.125) but it is more for brackets etc... not for skins and ribs and bulkheads. That you are using 1mm shows just how massive the beast is :)

    The thinner the skin, the easier it is to damage in assembly... a pneumatic rivet gun can cut right through it if you slip off of the rivet, or it is not properly backed on the tail when driven.

    Since it is a static model, will they be driven rivets, or will other easier fasteners such as pull 'pop' rivets be used in places?
    Driven rivets are still cheaper, but the $$$ in man-hours for assembly goes way up, just curious what you have decided as a balance for authenticity, money, and labor.

    I love the scan of you standing in the bulkhead. It puts it in perspective so much better than a stock image, I imagine even that much more so for you.
