Hey thanks Eric, actually not too hard at all.  It helps to have templates on file of 8, 10, 12, 14, 16 and 18 tooth gears, then print out as needed.

Next, glue it to a piece of wood.  Drill out all the hollows as close as possible. 

Cut the outer perimeter on the bandsaw, then it’s just a matter of cutting in towards the valleys.   

I love the paper as I can cut close, then sand half the black line off for a damn near perfect gear.  

All too much fun if ya have a need, ha!
