Lee Lyrics: There are several parts you need to build a rocket motor A nozzle and a closure and an insulator You shove them in a case and then you fill it up with sludge Don’t eat the sludge (it looks tasty!) The forward closure’s made of 6061-T6 It gets an O-ring then another then a 3rd in case one splits Tap the hole for the transducers That’s how you build a rocket motor! Now it’s time to make a nozzle and that comes in several parts A graphite throat, a carrier, a whole lot of heart These parts go on a lathe and then we make a lot of dust Don’t breathe the dust (I love my lungs!) The pieces go together and you seal them with ketchup Just kidding it’s not ketchup it’s room temperature vulcanizing silicone Now the nozzle part is over That’s how you build a rocket motor! And now it’s time, to make the sludge Delicious sludge, don’t eat the sludge!! (It’s not worth it!) You take HTPB, IDP, aluminum and mix Then add the perchlorates, yum! Now MDI, to cure the mix And then you vacuum degas all the bubbles til the sludge gets thick And when you’re ready pack the tube with 40lbs of cookie dough And then you wait a bit, just a bit sec Finally, remove the core And that’s how you build a rocket motor! Can we be done? No! Now there’s one more step that’s left before we see if this thing works We’ve gotta build a test stand and then work out all the quirks Now we fill the thing with water, and pressurize it hard 69 bar (nice!) The motor passed a hydro-test so now let’s light the match But first we’ll get it polished to ensure that it looks snatched And don’t forget the paint good sir Cause that’s how you build a rocket motor!
