New to hobby (Nov.09), but I've enjoyed making a few of my own scratch builds. My 'Peanut' rocket was one of our first few... https://www.rocketryforum.com/showthread.php?t=9241
I am trying to make (another) NC for it, (it doesn't like being lawndarted ) The first few turned out ok, but I'm trying to find an easier way to make large cardstock cones. I coat the inside with a couple layers of yellow glue, quite sturdy...
I found this... https://mathforum.org/dr.math/faq/formulas/BuildCone.html but I don't have a scientific calculator, and I wouldn't know how to use it anyway.
The 'Peanut' has a ~4" diameter. I have "case 5" where 'r' is 2 and 's' is 8. Can someone help me figure the rest of the equation? What if 's' is 7? 9? Do these equasions figure for overlap (glue strip)? I assume not...
These are going to have to be drawn, not printed, because 8 1/2 x 11 paper is'nt large enough, or am I missing something?
I've tried this https://www.delorie.com/rockets/transitions.html , but, again, the printer paper is too small. I guess to make a cone from a transition, dont cut the inner circle, right?
TIA
