I have some of the modifications that I'm working on. I'm hopefully improving the alignment of the axles and the bearings. The bearings are in the stand itself and not the wheel.
I'll need to make 2 roller assemblies tomorrow so I can connect both levers so I can have maximum force. Once I have the wheel back on it's stand, then the bellows will be the only thing left so I am trying to finish this quickly.
What doing the torque demonstration did was let me know that if both of my levers work together, they will generate the same amount of force as the pressure head will have resisting the opening of the bellow. And by adding 2 ounces of weight to each 1 lb. weight, I'll have enough force to open my bellows.
At the same time, I'll have a bout 3 in. lbs. of torque to rotate my wheel with. It won't be much. But as Bessler himself said, with one set of tongs, his wheel rotated slowly. Still, I guess engineering isn't for everyone and Scott doesn't have a section in the forum for discussing it and how it relates to work.
