Overthinking things much? Just find a spiral on google images, open in photoshop, print, then I think edit, flip horizontally.

 

if you want to over think the spiral then here are some mathmatics to ponder you need to pick your spiral

Logarithmic Spiral
The logarithmic spiral is a spiral whose polar equation is given by r==ae^(btheta), where r is the distance from the origin, theta is the angle from the x-axis, and a and b are arbitrary constants. The logarithmic spiral is also known as the growth spiral, equiangular spiral, and spira mirabilis. It can b

Cornu Spiral
A plot in the complex plane of the points B(t)==S(t)+iC(t), where S(t) and C(t) are the Fresnel integrals (von Seggern 1993, p. 210; Gray 1997, p. 65). The Cornu spiral is also known as the clothoid or Euler's spiral. It was probably first studied by Johann Bernoulli around 1696 (Bernoulli 1967, pp. 1084-

Archimedes' Spiral
Archimedes' spiral is an Archimedean spiral with polar equation r==atheta. This spiral was studied by Conon, and later by Archimedes in On Spirals about 225 BC. Archimedes was able to work out the lengths of various tangents to the spiral.The curvature of Archimedes' spiral is kappa(theta)==(2+theta^2)/(a

Archimedean Spiral
An Archimedean spiral is a spiral with polar equation r==atheta^(1/n), where r is the radial distance, theta is the polar angle, and n is a constant which determines how tightly the spiral is "wrapped."Values of n corresponding to particular special named spirals are summarized in the following table, tog

Fermat's Spiral
Fermat's spiral, also known as the parabolic spiral, is an Archimedean spiral with m==2 having polar equation r^2==a^2theta. This curve was discussed by Fermat in 1636 (MacTutor Archive). For any given positive value of theta, there are two corresponding values of r of opposite signs. The left plot above

Natural Equation
A natural equation is an equation which specifies a curve independent of any choice of coordinates or parameterization. The study of natural equations began with the following problem: given two functions of one parameter, find the space curve for which the functions are the curvature and torsion.Euler ga

Hyperbolic Spiral
An Archimedean spiral with polar equation r==a/theta. The hyperbolic spiral, also called the inverse spiral (Whittaker 1944, p. 83), originated with Pierre Varignon in 1704 and was studied by Johann Bernoulli between 1710 and 1713, as well as by Cotes in 1722 (MacTutor Archive).It is also a special case o

Logarithmic Spiral Evolute

Nielsen's Spiral
Nielsen's spiral, also called the sici spiral (von Seggern 1993) is the spiral with parametric equationswhere ci(t) is the cosine integral and si(t) is the sine integral.The arc length and curvature are given bywhere the arc length is measured from t==1.This gives the Cesŕro equation as kappa==(e^(s/a))/

Superellipse
A superellipse is a curve with Cartesian equation |x/a|^r+|y/b|^r==1, first discussed in 1818 by Lamé. A superellipse may be described parametrically bySuperellipses with a==b are also known as Lamé curves or Lamé ovals. The restriction to r>2 is sometimes also made. A range of superellipses are shown

^^ Damn rep for all that - looks like logarithmic is the easiest to plot.

93ex, I need a formula to tell me where to drill holes on a grid to make them all appear to be in a perfectly straight line. I tried tracing but the finished product will always be slightly imperfect from a trace unless you plot the exact spot to drill each hole.

 

If you were to draw it in cad, then someone with a CNC could make them exactly the same everytime.

Fixed.

 

did camron paint your bumper?

 

no some crackhead did it for some ketchup packets.

i pmed you toby...

 

haha. i was gonna say he woulda took the bumper off the car and detrimmed it to paint it. cheaper painters like macco just tape shit off and get over spray everywhere.

 

yep, it was teh weak sauce paintjob. but my bumper is shiny and white so im happy.

I'm really starting to feel the spiral thing. If toby can cut the shape them I think im sold on it.
