Why the Pi Divider don't work right.........

z' is less than z by

the thickness of one

cane

n= number of canes

x= diameter of cane

y= nx= Πz

z'= Diameter of inner circle,

or moil diameter

y'= Πz', or perimeter of moil

How many canes short should

we set the Pi Divider?

y=Πz, so

z=y/Π

z'= z-x

y'= Πz'

= Π(z-x)

= Π(y/Π-x)

=y-Πx

Since y=nx,

y'=nx-Πx

so, distance short to set the Pi Divider, d, is

y-y'

y=nx

y'= nx-Πx

d =nx-(nx-Πx)

d=Πx

x= diameter of one cane, so set the Pi Divider a bit more than three canes short
EVERY TIME, EVERY LENGTH, EVERY THICKNESS
(theoretically).

If you are picking up a slab, or murini setup, set the Pi Divider short by
Π times the thickness of your pickup
