Our host also realizes that more parts—like the combustion chamber—will have to be made out of metal as well, so through the course of the video, he buys a welder and learns to weld. It doesn’t go great, but nevertheless, his welds hold. Again, we’re not looking for perfect workmanship here, we’re looking for that magical turbojet start-up.
And… it does. It seems like something isn’t quite right with this stubby little engine because the run is only brief and comes after several attempts and a few modifications. However, this home-built turbojet runs for real, in this guy’s attic, and a lot of it is 3D-printed.
We’ve actually covered similar backyard jets before, like one grafted onto a rail car, or another that actually uses two turbochargers for a very interesting effect. Needless to say, if a backyard engineer gets it in their mind that they want a jet engine, they’re going to make a jet engine.
Now I just need to find a safe spot in my apartment to put a fab shop…
