Iggy, I bet many (like myself) wouldn't know how to run this script or input

I have no real need as I know enough trig
(Some Old Horse Caught Another Horse Taking Oats Away)
to quickly sketch it out and run an excel speadsheet for the calcs.

For those running Windows and don't know what to do with a
Perl script check out Marv Klotz's Utilities:

http://www.myvirtualnetwork.com/mklotz/#shop

He has two versions (maybe more) for doing a similar calc
for bolt circles:

"BOLTCIRC.ZIP (~31 Kbytes) 10/04/05
It's often easier and more accurate to lay out holes on a
boltcircle with x-y coordinates than to scribe and step off
the circle, especially if the number of holes is an unusual
number. This program does the work and generates a table
which you can print and carry to the drill press for
reference. See also CHORD."

"CHORD.ZIP (~19 Kbytes) 02/24/00
For those who insist on marking out subdivisions of a circle
the old-fashioned way and don't want to use BOLTCIRC, this
tool will compute the chord length needed to divide a circle
of input diameter into any number of parts. See also
BOLTCIRC."
