Ok, it's fairly obvious I wasn't clear enough (I can't even figure out what I
meant <grin>) so here is a second attempt. The part I am using as the major
component of my foot design is the (aucZILLA designation)1x4/2x2 corner-connect
plate hinges. Using 1, 2, and 3 to represent stud locations from the three
hinge-plates, I will attempt a clearer ASCII drawing. 'x' represents the
equilateral triangle formed by the three sides - hence the original title of my
post. The '/' are there because LUGnet tried to interpret this as a .dat file
without them.
/ 1 3 3 2
/ 1 3 3 2
/ x
/ 1 2
/ 1 2
Essentially, a perfect 120 "y".
That still doesn't quite get the angles right, but I think it gets the point
across. I have connected the hinges together with 2x2 plates over each of the
three 'sides' so there is no freedom of motion in the hinges (alternating these
layers makes for a very solid structure), and am trying to figure out a way to
anchor a single larger plate to all three orientations.
My original question still stands - does anyone have a solution for me?
