I'm thinking that I can fabricate one of these with a machined header,
machined ends, and a section of tube. *But it'll all be aluminum, so how

Could you use machine screws to hold the header to the front machined
end? And then run a threaded rod through the tube to hold the
machined ends.

Or use lost wax casting to make it as one piece.
