Hi Slunnie
If you build one you need to build some sort of clutch mechanism into it.It needs to be easy to pull but needs to clutch as you slow down on the pull,if not it will over-run and give you an instant birdsnest.
I would look at a GOOD working jenny closely then copy it,wouldnt try re-inventing the wheel.Havent seen one using bearings,I feel it would spin too fast!!!
Another tip if you are doing a plain wire fence.Sit the jenny in the middle of the fence,run the wires each way to the strainer and use those gripples,they are the bees knees



Enjoy,once you build a good fence you will want to fence veverything
