Shroud Calculator
September 9, 2008

I needed a pair of shrouds for my Celestial Navigator rocket, so I looked online for a shroud calculator. The choices I found didn't thrill me (as I don't have a ruler marked out in inches to three or so decimal places) so I wrote my own. Mine accepts not only the measurements of the tubes in question, but also offers pulldowns to choose from standard Estes and Centuri/Semroc sized tubes. Results are presented in decimal inches (to three places), fractional inches (accurate to 32nds of an inch) and millimeters (rounded up).
