I'm not actually sure why it would be any easier than the normal one.This one might be within my build skills.
Having completed the solipsistic exercise of creating goonies of my own designs, I will now be focusing on two brand new designs, one sci-fi (I have ideas) and one just a plain sport rocket (nothing in mind yet). Of course I will post any other stupid idea that comes to mind in the meantime.
How about the 220 grit matte finish for the paint followed by satin clear coat?220 roughs it up enough to make it *extremely* matte and emulate the surface feel of an eraser a bit better, but I think the smoother finish will be more durable.
A power tool of some sort is the way to go. Ditch score and snap.My next big obstacle is figuring out how to cut the Lexan fins cleanly.
I guess I'll give it ago with a jigsaw. I don't have one but my Dad does. What do you do with the protective film? Can the saw cut through it without getting fouled? Pre-cutting the film in perfect alignment on both sides seems difficult.
Also I guess you really need to clamp down the sheet.

How to decide how long to microwave a potato.Fly it with the 1/16th. If it breaks you need the 3/32nds........
Yes, I am a smart @ss......
That is my hope. I'll be looking at D and E motors for this thing, probably, LPR-like velocities (this is not the rocket I'll be sticking an F44 into).For low power, I think you'll be fine with 1/16".
Lexan and acrylic are much more rigid than the equivalent thickness of balsa.
Plus no grain.
Fair. In this case though I'm hoping to sponge off the experience of others if possible. At the moment I don't have a piece of 1/16" lexan to test with (anyone know where I could find some at retail?)But seriously, folks. When in doubt, test. And please test responsibly.
How do I determine if 1/16" or 3/32" Lexan is needed? There's a useful weight savings with the 1/16".

Space X Falcon 9 kit, 1/16" clear fins.

Gee, now you got me thinking. I'm not an engineer either, but I would have to amend my statement to say that plastic fins may be more elastic than balsa depending on the direction of the force (i.e. with or against the grain).Although I went to an engineering school, my degree is in biology.
Is rigidity equivalent to durability, in this case?
So what is Young's modulus for balsa wood?You can look up Young's modulus for most materials you like--steel is around 29000 ksi, and Lexan is around 300 ksi.
