Anyway, I can see you like the bolts.

It kinda' more in lines with what the Wright brothers would have
used,

In keeping with the way the brothers might have done it - how about
drillining 3 holes in a couple of pieces of wood of the diameter needed
to fit the EMT and the bicycle tube, saw in half and bolt together
clamping the tubes together? Might need 3 sets of blocks to keep
things torsionally rigid.
