Default welding technique for clusters

Stealth,

I know exactly what you're talking about. The clamps that held Wilbur
Wright's test "air plane" and flat plate to the bicycle-wheel-thingy
of the 1901 aerodynamic experiment are made that way (on a much
smaller scale).

For those of you that think airfoils are the subject of University
wind tunnels, Reynolds Numbers, and other such ilk, you may find it
interesting to know that good 'ole Wilbur Wright made his first
aerodynamic studies by mounting them on a bike wheel attached
horizontally to another bike. The apparatus's power source was only
rated at one "Orville", but that was sufficient to determine that
Smeaton's coefficient of air pressure was flawed. The follow-up tests
were run in a wind tunnel made of pine boards.
