Square steel tube is great stuff. A simple mahogany and birch plywood top, a sliding straight edge, a task light and you have the table upon which most of my early design work was accomplished.
Computer aided drafting collapses the boundary between drafting and lofting - an absolutely incredible thing. I could never ever go back - CAD provides absolute accuracy and the amazing suite of productivity tools. And yet it is a meloncolie advance since lofting is one of the really high order activities. Just memories now.
Recently when helping a friend build masts for his 40-ft sailboat I had my hands on some 25-ft sitka spruce lumber. I wanted so to make some long lofting battens . . . but there really is no need, lofting is gone.
