Oh but there is... Remember the old style differential? I don't have one, but it
defenitely has 28 teeth. Perfect for getting a 2:1 ratio with a turntable. I
doubt the chain will fit over the crown teeth, but I might have to try.
Otherwise, the gear could mesh directly with the turntable with a 0.5 stud
offset like the 16t gear requires.
Anyone want to give/loan/sell a couple of these to me?
