Email Wrap-up

Larry S.:
"Hey Guys,  Thanks to everyone who was able to make are meeting Sunday.  I think we got alot done.  Here are some highlights.
-  I had no idea that Neil was able to draw so well.  ( Joe should have pictures posted soon )
-  We have enough griblies and 1/32 scale figures to do the next 5 projects.
-  Ken has taken the job of making us some 1/32 scale railing.
-  John Lester has donated some
Rebel-Bomber engines to the group to use as we see fit.  ( Thanks John. )
We had a pretty productive meeting.  We were able to I.D. most of the problem areas with this project.  One major problem is at 1/32 scale this thing could end up being huge.  So we will have to change the set up in order to make this project happen.  The group does seem pretty committed to keeping this baby at 1/32 scale, and to having an overhead crane.  We agreed to meet on a Sunday prior to the next club meeting.  No specific date has been set as of today.  So please keep posted.

Thanks Larry Senior.

Sparky:
Quick note for helping figure the sizes of the column's feet.  From geometry/trig, there's a saying. stub your toe?  Go Soak-a-Toea, SOHCAHTOA.
Sine = Opposite over Hypotenuse
Cosine = Adjacent over Hypotenuse.
Tangent = Opposite over Adjacent
So if you know the height to where the sloped edge will go, say 20 inches, and the angle that looks good is 30, then pullup your computer's calculator switch it's view to scientific and find 20 / Tangent of 30, its 34.64 inches.
This is how much base you'll need sticking out from the main column on the side with the long angle, add 11.54 inches for the side with the 60 degree slope, and don't forget the width of the column itself. Now you can figure the foot print of the leg or hill side right on the concept sketch page
