Good stuff Javery! I know what you mean with mounting the 2nd side to the bearing.. ran into that as well on mine. I think the three inch bearing was a better choice over the twelve for less play. Did you have to do anything fancy to allow room for the VESA mount, since the three inch bearing essentially covers the space the VESA mounting holes were spaced for, or did I miss that in the pics above? Do make sure you get your Secret Motor driver working, and see if that motor is strong enough to turn your unit also, before declaring success
You might also want to pic up a can of that plastic spray "Dip" coating stuff, depending on the friction you get. I've got a can on reserve just in case.
I was messing with it this morning, and I'm pretty sure I have about 1/4" play in my bearing.. booo!! Stay away from the twelves!
The good news on my front, is that I'm stocking up parts for Good Friday, when I have off work. I have everything I need to mount my monitor, and I'm pretty sure this method is going to be way better then my old one.
