Mine is on the way from Penn tool, I have a few light Modifications to do when it gets here, then hope to post a video of my Peanut Rider doing work.
Do the black upright bearing towers have oiling holes?
Nice photography BTW
No, but it would be very easy for you to file them flat, turn up some oil cups and mount them 
That IS my plan! Everyone seems to make there oil cups from brass....so mine will be turned from solid copper, because I have a bunch of copper and because....I am just "that guy"
