Questions about Ball Mounted Pillow Block Bearings

I thought of that, but I would somehow have to marry that to a shaft that would allow me to mount timing gears of various sizes. My research down that road didn’t get too far before it looked like the barriers were getting too big.
Also, partly in the spirit of the V1 ethos and partly because of the fact that I’m frugal, I want to keep the cost to a minimum.
I would like to think that others may want to build this and wouldn’t want cost to be a barrier. (I learned that from my buddy, Ryan)
