Just a few suggestions:

1a) Take a good, sharp close-up photo, making sure that the camera is
square with the gear. Blow it up to several times actual size and take
your measurements off the print. You can help this along by including a
ruler in the photo for scale (or scribing some lines on the gear).

If you have a scanner, put the gear flat in the middle of the
scanner's plate, and scan it. That will probably be as good an image as
you can get, and will make sure that the "camera" is square with the
gear.

Use the highest resolution (maximum DPI setting) on the scanner.

You can possibl even use a sub-program in an image processing
software package (e.g. GIMP or PhotoShop -- whichever you have) to get
an outline of the gear -- better to work on importing that to a CAD
program.

Good Luck,
DoN.
