Hand crank arm to handwheel ration
[ATTACH=CONFIG]578459[/ATTACH]SteveH and I got to discussing gear ratios for hand cranks. This German Kohler machine spins the balance wheel 2.1 times per revolution of the hand wheel.
[ATTACH=CONFIG]578457[/ATTACH] Davis spins 3:1
[ATTACH=CONFIG]578458[/ATTACH]Singer and reproduction singers spin 3:1
If one puts a steering wheel knob on a balance wheel (like I have), it is direct drive 1:1
Does anyone have others to check?
if you can see the attached Kohler shot please ignore. I was trying to delete it.
