Probably o.k. here if it's more of a manufacturing issue. There is a Gear and Pulley engineering sub-forum in the Mechanical Engineers forum. I'd use that if the question is more about engineering the gear.
What Im trying to make is 2 identical gears with 2.25 center distance, number of teeth doesnt matter, speed is slow for a hand crank.
I have 3 gear cutters marked as such.
Thanks
