Based on that description, I'll guess that the blue hard cover second from the bottom could be Jackson, "Classical Electromagnetism".
You're on the right track.
Probably way too late but what if you drilled a 1/8th or 3/16th hole from fin tip to root and then glued in a wooden dowel. Kind of like adding rebar.
Definitely not too late. So that would make a fin:
- stiffer, protecting it from a straight on landing.
- a little heavier in the back, so a little heavier rocket overall.
I think I'll be making a list of possibilities, and make a decision later. But I'll surely keep this in mind/on the list.
Using 0.75" boards, I calculate that you'll need 22.53 of them. So, if you use 23, you can sand just a little off the width of each one; that would be 0.015" off of each.
Or, use 24 of them, an even number that makes attaching the fins a lot easier. Then you'd have to remove 0.046" from each one. That's the way I'd go.
Agreed. Excellent plan.
I agree with 22.53, but the figure in fact won't be a circle, but instead perhaps a ... 24-sided polygon. Or as the smurf calls it: an icositetragon.
So I'll be trying "fit-tests" on the tube itself, just to make sure. But yes, 24 sounds like a great idea.
