Ever look at the formulas in Damon Rinard's Spocalc spreadsheet? I mean, I do pages-long derivations and proofs just for fun, but that stuff made me blanch. I'm very skeptical of black-box calculators, but Spocalc is one black box I use with gusto (and happily gives correct results).

What about spoke ends poking past the nipple flanges and into the tube? Does this present a puncture hazard, or is the rim tape enough?
