how do you measure out the teeth positioning? Or is that lump on the left a dividing head?
Yes it's a dividing head. I make 2 gears, 65 teeth and 68 teeth. The head is 40:1 ratio so I use a 39 hole plate and index every 20 holes for the 65 and a 17 hole plate and index every 10 holes for the 68.
What you don't (or shouldn't) do is try to cut 68 teeth in a 65 tooth blank coz that makes you very angry
