lugs are joints that join tubes--
the joint and lug is brazed.
most lugs are larger than the outside
diameter of the tube and thus are thicker.
I've heard of internal lugs working the other
way around--never seen them.
so for metal frames you basically have lugged
construction, fillet brazing and welding.
