Probably the easiest way of connecting tubes to form a truss, is to belt the end with a hammer (or press), and drill a hole.
Its similarly straightforward with wing construction to use the said tubes spanwise to carry the +ve and -ve loads.
These are methods I think Junkers empoyed in their 'heyday' with the 'J1' etc.
Regardless of modern regs, these aircraft flew ok, didn't they, and if they failed what aspect of these methods was deemed to have contributed to any related failure of which I have no knowledge?
The flattened tube ends were supported by the metal skins, or by something else presumably in other places (but not in all!!) Take a look at the extent that this method was employed on this machine.
I'm not advocating such a method just questioning its validity.
