[ATM] Plop Flop II The Sequel

[Jay Kirkland <jaykirk2@compusmart.ab.ca>]

I think I already have from Plop a really nice cell design. The thing is: I
have no idea how to read it. It's a 27 point cell with varying angles. I
chose 27 only because I'm going to stick the mirror to the support points
and this being the first time I've done this, I am totally paranoid. I'd
really prefer to attach it at 108 points, even tho 18, even 9 will probably
be strong enough and also supply great support. I figure 27 will be as easy
to make as any. In the end, I'll probably go 18 and astatic.
	But I still need to be able to know how to read Plop. 
	The radii are obviously radii of the support points. On a 20" mirror, my
radii are 3.43, 8.18, 7.76, 6.22, and 7.67". The angles are obviously the
angles that the support points are located. But when you go to parts
dimensions, what are those #s about??? For example, Part 4. This is the
triangle that supports the other 3 triangles. There are three corners to
the triangle. In inches, they are roughly x=0/y=0, x=1.9/y=4.2, and
x=4.6/y=0. The center of the triangle is marked x=.9/y=1.4. The COG of Part
4 is x=2.6, y=4.6, R=5.2, Angle =60.
	If you lay out Part 4 in a full size drawing using the radii and angles
specified, you end up with a triangle roughly 5"x5"x8". I'm assuming R4 is
one vertex, altho that's not totally clear either.
	No matter how I mix and match the numbers from the parts dimension
drawing, what multiples or combinations I use, where I start measuring
from, I just don't see anywhere where the #s from the parts dimension
graphic fit anything on the part. 
	I've tried this with 9 and 18 point examples as well and it's the same. 
	Hellllp! 
	Can anyone share the #s for the 3 corners/center/COG off a parts graphic
they've used (or for part 4 above)  and explain how those #s dimension out
into a real world triangle? 
	And thanks for the advice I've already received. Your suggestions are
always good and I do appreciate them and already I'm contemplating changing
a few things. . 

Dyslexically yours,
Jay
