Balanced Rotor and Spring Grease

[Tom Wesenberg]

I had a PM about balancing the distributor rotor, but the thread I found also has a picture of greasing the Model A spring, so I included that in the title.

To balance the rotor, I've tried a couple of ways, but removing the excess Bakelite and adding a couple screws is the easiest I think. I used my Dremel to remove the excess Bakelite from the circle, then used the Dremel to grind a couple holes for the two screws and nuts. It was basically just guess work, but the balance turned out great.

I used the same balancer that I used for the fans. You can also just use a couple of thin metal pieces to let the shaft roll on, such as a pair of razor blades. The small ball bearings I use have such low rolling friction that they work fine. If I spin the ball bearings against the wire wheel, that will limber them up for even less friction. I'd bet you could even rest the shaft on an ice cube to do the balancing. That should be low friction.
