Sam,post pics of the S1 in current state!
How's it going Sam, this jigger must be about finished by now! :lol:

What he said :D

Btw - this may be of some use:

And if you want to design the springs you want - rather than just bolting stuff together to see what happens ;) The leaf spring rate equation is ( from a post on AULRO):

k = 8.E.n.w.t^3 / 3.L^3 * SF

Where:
k = spring rate (lb/in)
w = width of leaves = 2.5" for all SII/IIA/SIII
n = number of leaves
t = thickness of leaves (when spring packs have different thicknesses - need to calculate a few times for each group of leaves of the same thickness)
L = length of MAIN LEAF - eye to eye, with the main leaf completely flat (See SIII manual a page or two back for those values)
SF = stiffness factor (basically a fudge factor to get the equation to fit real results) - for square cut leaf ends SF = 1.08 for Series FRONT springs and 1.13 for HD and Xtra HD REARS.
E = young's modulus. Which for steel is:
3.05x10^7 lb.in^-2 or 2.1x10^11 N.m^-2

Any hope to see anything before I fly down in 2009 to visit Ben
:finger: :D

I guess Sam went beyond simple leaves dimension already and fitted his own antigravitational devices instead...

He's probably orbiting over Oz at the mo trying to find the right setup...
