How can this turntable be made more solid?
He knows that both the crank and the rocker have axles, and the friction between the axle and the outer hole must be particularly high.
If powered by water, this device might wear out very quickly.
He could make this equipment with wood or steel.
He has plenty of steel, so he thought he could try using steel.
The animal-driven device should be quite similar to the water-driven one.
He could have a few animals turn a larger turntable, similar to how a millstone is turned, which would have a crank and rocker to drive a blower.
Ma Lin thought that a blower made of sheepskin bags, like an accordion, would generate more wind power than a bellows.
The movement cycle could be adjusted using a gear system.
The large gear meshes with the small gear, and the small gear would definitely rotate faster than the large gear.
