I was thinking of have the timing slow so that in late game it is ether impractical or used only as power backup for the windmill during storms.
(Always wanted to make a backup system using the storm detector, turntable and a gear box rather than turning it off)
Pottery would take longer to do on the turn table.
It could be used with the turn table as a form of down gear for slower turning times due to the power turning on and off. Similar to one turntable slowing another.
Hoppers would fill up in fast systems like mob grinders.
Bellows would take too long and the fire would die down.
Saws would take longer to cut things but it would work for some harvesting applications or cutting wood.
The pulley would never work.
In the early game levels it would be enough just to not stand next to the hand crank. 36 Hemp Leaves, 1 Hide and 9 cuts on the saw take a bit of just clicking. With the water scoop it would take longer but you wouldn't have to stand next to it. After getting higher in the tech tree it would work for special applications but otherwise it would just be aesthetic much like the wind mill becomes
