Back to the brushplate bearing topic:
Something I do that nobody has mentioned yet - I take brass tubing with 0.125 ID. I crimp the end to make a small flange on the press. Insert it snug tight with cyanoacrylate, with the flange on the inside face. I make the brass tube length slightly longer than the armature shaft. Then, I wedge a felt wick down into the tube up against the tip of the armature shaft and soak it with oil. I have a few engines, even a 313 bascule bridge that run as smooth as can motors now, and rarely need any attention.
