With the help of our friends in
mid-power, and Mr. Flis' super handy downsizing scaling factors, I came up with this:
___________________________ BT-50_____________ BT-3
Ball Diameter_______________4.875"_____________1.872
Overall Length_____________15.75"_____________6.048
BT Length__________________14.75"_____________5.664
Length of BT inside Ball____3.875"_____________1.488
Fin Root Length_____________1.9375"____________0.744
Fin Tip Length______________1.1875"____________0.456
Fin Semi-Span_______________3.6875"____________1.416
Fin Sweep Length____________0.75"______________0.288
Fin Thickness_______________0.125"_____________0.048
I'll probably start with 1/32" balsa and paper it to get to 0.048 though in my opinion that is really the least of my concerns.
I ran down to the local Michael's and found some 2" styrofoam balls - 6 for $5. They don't register on my gram scale so I'm guessing they are pretty light. The biggest problem is the texture - its that open, flaky blown foam stuff -- not at all like a Death Star. If you saw a styrofoam ball the size of a small moon, I doubt if you'd feel much terror...
As an experiment, remember I have a few to sacrifice, I caked it with Elmer's filler with the hope that after a little light sanding and some good primer it might possibly cause fear in the colonies of ants at the field.
I'll post pics of this experiment after it dries. If it didn't work I'll edit the thread and we can all pretend it didn't happen.
I have a few minor problems....
I don't really know how to cut it accurately into quarters. I'm certain the razor saw is the tool of choice, but how do I mark the lines?
Also, the only piece of BT-3 I have lying around is nicely packaged in one of Mr. Flis' Tog kits. I can use it for marking, cutting and experimenting with the Death Star, but it's way too short to actually use.
