Each fluorescent lamp that illuminates the Worthy project is supported by two pieces of bent 1-½” steel tubing. My test of a single-radius bend looks boring, and so I’m going to try a double-radius bend. But what radii? After some math, I can plug different numbers into r1 and r2 until the curve looks good. Then I’ll compute the limits L1 and L2 for the tubing roller.
