1) Square up the plate on a drill press.
2) Drill out the bearing with an appropriate bit (in this case, a #12 bit, .1890 inch diameter).
3) Press bushing into place. Secure with ACC or epoxy glue.
Maybe I am over thinking this.
Getting the drill bit square with the brush plate is no big deal. positioning the hole is what I was thinking about. I guess one would assume that centered on the worn hole is the correct position?
Oilite bearing are oil impregnated, will glue stick?
I saw some .125 ID flanged oilite bushing on EBay. As was pointed out earlier, they might not fit between the brush holders.
Some time ago I thought somebody wrote about using brass eyelets.
Machining my own parts is not possible for me, and I suspect for many other folks. I don't have any machine tools.
